Level, Spill, Leak, Moisture Detectors By JOLA GmbH (for Hazardous Areas):

LEVEL MONITORING:

JOLA Floating Switches and Immersion Probes:
Mercury-free floating switches and immersion probes Controlling devices
with ball-operated micro-switch, for signalling or control of liquid levels

JOLA Float Switches SM Ex:
SM… float switches Control units with rod operated micro switch
for liquid level indication or control of liquid levels for electrical systems
and for pneumatic systems

JOLA Immersion Probes TSR Ex:
For signalling or control of liquid levels. For use in low viscosity, nonadhesive liquids that are free of solids and do not attack the component
materials

JOLA Magnetic Switches and level indication with TAPS:
Magnetic switches, level indicators with taps and level controllers with builtin magnetic switches for level control in tanks

JOLA Continuous Level Measurement (Float Method):
Continuous liquid level measurement with TSQ 4-20/… and TSK 4-20/…
liquid level indicators for remote transmission of liquid levels using
the float method
JOLA Continuous Level Measurement (Bubbler method):
PKG 4-20 Liquid Level Transmitter for continuous level measurement
for remote transmission of liquid levels using the air bubbler method
Due to the force of gravity and as a function of the specific gravity of the
liquid, the pressure at the bottom of a tank is proportional to the liquid level
in the tank. The pressure corresponding to the liquid level is measured by
means of an immersion bell mounted just above the bottom of the tank or
an immersion tube which is open at the end and suspended slightly above
the bottom of the tank. An air pump integrated in the liquid level
Transmitter pumps air into the bell or tube via a hose for 10 seconds every
50 seconds. The air pressure at the bottom edge of the immersion bell or at
the end of the immersion tube following the injection of air is equal to the
pressure generated by the liquid. The air pressure in the immersion bell or
immersion tube is measured by a pressure sensor integrated in the liquid
level transmitter and converted into a load-independent current signal of
between 4 and 20 mA via an integrated current loop transmitter.

JOLA Conductive controlling devices (water, acids etc):
For automatic control, regulation and signalling of liquid levels Electrode
controls are used for the automatic control of pumps or electromagnetic
valves as well as overflow or run-dry protection in wells or tanks with
conductive liquids. The liquid levels are monitored by electrodes which give
switching commands to the electronic relay if they come into contact with
the liquid.
JOLA Capacitive Level Controllers (water, acids, oils, solvents):
For automatic control, regulation and signalling of levels of conductive and
non-conductive liquids or pourable bulk goods The function of the proximity sensors is based on the change in capacity of the electrode located in the active surface of the proximity sensor. This change in capacity is generated by proximity or contact of the liquid/pourable bulk good
to/with the active surface of the proximity sensor.

JOLA Protection and Alarm Relays:
Protection relays: for connection of binary sensors (e.g. Jola floating
switches or Jola immersion probes) or for connection of Namur-sensors
(e.g. inductive or capacitive proximity sensors)
Alarm relays: for connection of several relays to one alarm relay or
for connection of binary sensors (e.g. Jola floating switches or Jola
immersion probes)
JOLA Liquid Leaks or Spills:

JOLA Leakage Detector Leckstar (Conductive e.g water, acids):
For use in conductive liquids like water, acids. Utilises plate electrodes,
rod electrodes, suspension electrodes with cable breakage monitoring. As
soon as a trace of a conductive liquid creates a conductive path between
the two electrode plates, a control current flows from the corresponding
electrode relay. The latter is then energized and a contact is made via the JOLA Leckstar 101 Relay.

JOLA Leakage Detectors Leckmaster (Capacitive e.g for oils, solvents,
fuels):
For conductive and non-conductive liquids; can basically be used for the
detection of all low-viscosity liquids for such tasks as signalling the
presence of fuel oil on the floor of a tank room or in a collection tub
located underneath a fuel oil burner. The COW/L and OWE 2/C sensors
are designed for connection to the Leckmaster 101relay.

JOLA Leakage Detectors Leckwatcher (Conductive e.g water, acids):

JOLA Types of detectors:
Point sensors: leakage detectors which can detect leakage at a specific point: plate electrodes, wall-mounted electrodes, rod electrodes, suspension electrodes
Line sensors: leakage detectors which can detect a leakage over the entire length of their electrode leads having cable electrodes or tape electrodes
Surface sensors: leakage detectors which can detect a leakage over the entire surface area of a network of interconnected electrode leads:
– sleeve electrodes

JOLA Leakage Detectors Leckwatcher (Capacitive e.g oils, solvents, fuels):
JOLA Types of Detectors:
JOLA Capacitive suspension sensors with stainless steel housing
JOLA Capacitive suspension sensors with plastic housing
JOLA Capacitive plate sensors with plastic housing
JOLA Leakage Detectors Liqui-Switch (Conductive e.g water, acids)
Designed to signal the presence of a conductive liquid caused, for example, by burst pipes. Plate electrodes should only be used in normally dry environments. They must be installed on the floor in such a way that the sensor side faces downwards and the label side upwards.
JOLA Leakage Detectors Liqui-Switch (Capacitive) for oils, fuels, solvents:
For signalling the presence of a non-conductive or conductive liquid. Can in principle be used for all low-viscosity media – e.g. for signalling the presence of heating oil on the floor of a tank room or in a collection tub located underneath a heating oil burner. Capacitive suspension sensors should only be used in normally dry environments.
JOLA Leakage Detector L-Pointer (Conductive):
The conductive leakage detectors can only be used for the detection of leakage of conductive liquids like water, caustic soda, hydrochloric acid, nitric acid, ferric chloride, and similar liquids.

JOLA Leakage Detector L-Pointer (Capacitive):
For oils, fuels, solvents for extra low voltage SELV or PELV, for connection to NAMUR isolation amplifier or NAMUR fieldbus terminal. The capacitive leakage detectors are primarily designed for the detection of leakage of nonconductive liquids but can also be used for the detection of conductive liquids.
JOLA Floating Electrodes for Oil in Water:
For detection of a thin layer of non-conductive liquids with a lower specific gravity on top of conductive liquids with a higher specific gravity. Floating electrodes are designed for use only in pits, reservoirs, and pump shafts, separator plants for light liquids or similar areas.

 

OTHERS:
JOLA Moisture or Condensation Detector (cooling ceilings):
FTS/KO-1 film sensor for cooling ceiling controller. The FTS/KO-1 film
sensor is a PCB film which can be stuck to a copper pipe or an even
metal surface. The back of the film sensor is coated with an adhesive
agent and a protective film. The film sensor is equipped with parallelrouted
printed conductors (sensitive surface) which are gold-plated for
improved surface protection. The sensor acts as a conductivity measuring
cell. The conductivity is measured using alternating current in order to
prevent corrosion and polarisation effects. The sensor is available with
connected 3-metre long thin white wire. Other connecting line
lengths are available on request
The film sensor should be installed at the point in the cooling ceiling
system where moisture is most probably expected to occur.
JOLA Limit Switches with ball operated micro-switch(RK, RAT-Ex):
The limit switches RAT/./E/Ex-1G are recommended for use wherever the
use of conventional flameproof encapsulated limit switches is difficult due
to demanding ambient conditions. Such conditions include, for example,
wet or soiled environments. The specific limit switch RAT/./E/Ex-1G is
mounted via a continuous borehole in the head section of the unit.
The limit switches RAT/./E/Ex-1G are fitted with a micro-switch
(changeover contact) as electrical switching element, and this element is
activated by an internal metal ball. Switchover takes place when the limit
switch is positioned approx. 17° +/- 8° above or approx. 3° +/- 3° below
the horizontal plane. The model RK is external mountable limit switch.
The limit switches are not suitable for use on rotating shafts.

Level controllers for rainwater utilisation systems

ALVI Automation (India) Pvt Ltd in association with ALVI Technologies brings to you the state of the art German Technology based Level controllers for rainwater utilization systems by JOLA GmbH.

rain water

Level controllers for rainwater utilization systems, FNR range

Operating principle
The components of the FNR range are an FNR fresh water refill controller and one or more suspension electrodes. The FNR 5 and FNR 7 fresh water refill controllers operate according to the conductive measuring principle.
In combination with an LWZ suspension electrode, the FNR 5 is used for purposes such as the controlled refilling of fresh water into a rainwater tank. If the level in the rainwater tank falls below the minimum fill level, a relay output activates refilling of fresh water (e.g. via a solenoid valve). Once the minimum fill level has been reached again, the switching status of the relay output is maintained for the duration of the delay time of approx. 10 seconds (standard) and the refill function is then switched off again. This time delay serves to suppress multiple switching actions in the event of wave motion and results in a level hysteresis whose magnitude depends on the tank dimensions and the strength of liquid inflow.
If, during the refilling cycle, the minimum fill level is not reached again within the monitoring time of approx. 30 seconds (standard), the relay output for refilling is switched off, and a second relay output is activated to issue an alarm due to timeout. This feature is designed to prevent uncontrolled refilling in the event of tank rupture or inflow defects, as well as in the case of electrode cable break, if ther is ice on the electrode or if the electrode has been removed. The various switching statuses are indicated by LEDs. In addition to the features described above, the version FNR 7 is also equipped with 4 LEDs to indicate the tank fill level, and these LEDs are individually controlled via 4 EH or EHK suspension electrode.

Lithium- Ion Battery Fires – Hydrogen Fluoride Detector

Gas Safety Risks: Lithium- Ion Battery Fires – HF (Hydrogen Fluoride Monitoring Systems)

Li-Ion batteries are now widely  used in mobile phones, electric vehicles, laptops including MW range of Renewable Energy Storage plants, aircrafts, submarines, mine-shafts and spacecrafts.

Gas Safety risks  in Li-Ion battery charging rooms:

  • Li-Ion batteries when overcharged or short circuited are overheated and catch fires
  • Li-Ion battery fires have caused great concern because of risks due to spontaneous fires and intense heat generated by such fires
  • As a result of the above-said a lethal amount of toxic Hydrogen Fluoride Gas, HF is generated.
  • HF from Li-Ion battery fires can pose severe gas safety risks in confined spaces like battery charging rooms, renewable energy storage plants in solar or wind power plants
  • The electrolyte in Li-Ion battery is flammable and generally contains Lithium Hexa- fluoro -phosphate (LiPF6)
  • In the event of overheating due to overcharging or short circuiting  and backed by high temperature, the electrolyte in Li-Ion batteries will vaporise liberating toxic gases like CO, CO2, HF (hydrogen fluoride)
  • The moisture and humidity will further exacerbate the situation generating more HF (reaction of LiPF6 with water or humidity)
  • Typical HF concentration expected can be as high as 20-200 ppm of HF (NIOSH/USA Safety limit , TWA:3 ppm HF, STEL: 6 ppm HF)

Solutions:

  • Continuous monitoring of HF, Hydrogen Fluoride in toxic range of NIOSH/USA : 0-10 ppm
  • Continuous monitoring of other toxic gases like CO, CO2 (gases generated due to  combustion fires)
  • Continues monitoring of humidity and temperature
  • VEFSA (Very early fire and smoke alarm)

Typical Systems:

  • Single Point stand alone gas controller for HF, CO, CO2, Temperature, Humidity
  • 1-4 channel HF, CO, CO2 Sensor/Transmitters with 4 channel Gas / PLC controller
  • Warning alarm to plant people including GSM Alarm dialler capability to mobile phones
  • DIGITAL MULTI-CHANNEL system for Renewable Energy Storage Plants for HF, CO, CO2, Temperature, Humidity
  • Save 60-80 % costs on cable, cabling, installation with our DIGITAL SYSTEM

VEFSA: Very Early Fire and Smoke Alarm: For very early fire detection in electrical cabinets, switchgear rooms. Our sensing system is designed to pick up enhanced gas radicals which are liberated during overheating of PCBs, electrical insulation breakdown due to short circuit or earth fault, transformer insulation breakdown, again due to short circuit or earth fault. Please note  by the time the conventional fire detection system like VESDA or conventional smoke sensors  pick up the smoke, it is already too late. Our VEFSA Gas Radical Sensing System can detect the gas radicals and shut off the mains/power supply thus protecting millions of dollars of assets
