Differential Pressure Switch for Water Chiller Plant & Industries

The differential pressure switch type DS34 is
suitable for all non aggressive gases and fluids, as they are: service water, heating water, neutral gas, oil, oily water…!
Applications can be named in:
• filtration systems
• process technique
• machine building
Function
The differential pressure switch is build
around a rugged, reliable membrane sensing
system.
It is suitable to detect vacuum, over pressure
and differential pressure.
In every application the switch is working on
the same principle. The pressure or differential
pressure to be measured generates a force
on the membrane. This force moves the
membrane in one direction against the
measuring range spring. A plunger fitted to
the membrane operates a microswitch when
attempting the adjusted switch point.
The switch point is adjusted by means of an
indicating dial.
Technical Data DS34
Pressure range 0 – 0,6 bis 0 – 6 bar
Max. operating pressure 16 bar (overpressure and vacuum proof up to 16 bar)
Max. environmental temperature -10…70°C
Max. medium temperature + 80°C
Pressure chamber Grivory
Membrane Stainless steel ANSI 301
Pressure connections Thread G1/8 female; other see ordering code
Mounting Mounting base upon request
Electrical connection pre-wired cable 3×0,5mm²

Digital differential pressure transmitter with 4-digit colour change LCD – DE39

ALVI – India in association with ALVI – Australia takes pride to offer Display and switching device for Differential pressure of gaseous and fluid media.
Typical applications
• Differential pressure measurements in heavily soiled media
• Filter monitoring
• simple pump control systems
• Pump, compressor monitoring
Design and mode of operation
The device is based on an electronic evaluation circuit that analyses the measuring signals P+ and P- of two integrated ceramic pressure transmitters. The signals are digitalised and sent to the analysis unit for further processing. Both signals can be shown separately.
The main feature is the calculation of the differential pressure. The analysis allows two independent switch points to be set and makes two programmable output signals available. The first output signal (channel 1) is proportional to the differential pres-sure and can be influenced by means of rooting or a table. The second output signal (channel 2) is proportional to the pressure and can be assigned optionally to the signal P+ or P-.
The nominal pressures of the integrated sensors and the differential pressure measuring range are set permanently ex-works and stated on the  type plate.

Liquid Level Detection – Well Probe.

ALVI India in association with ALVI Australia takes pride to offer Fischer – NB10 Well probe for liquid level detection.

Application

Measuring probes for hydrostatic measurement of fluid fill-levels. Some examples of typical applications are water or fluid fill-level measurements in
• Wells
• Drill holes
• Wastewater systems and
• Containers
Most Important Features
• High measuring accuracy
• Low hystersis
• Corrosion-resistant materials
• Integrated measurement converter
• Measured values stable over time

Design and Principle of Operation
This measuring probe is designed around a highly sensitive pressure sensor with a silicon membrane-measuring element.
A DMS resistance bridge is attached to the rear of this membrane using a thin-film method. The well probe is equipped with an indirect hydraulic pressure sensor in order to guarantee the system-inherent dead space latitude. The pressure sensor is isolated by an elastic membrane from the medium to be measured. The volume between the membrane and the pressure sensor is filled completely with a transfer fluid. When pressure is applied this silicon membrane deforms in the elastic region, altering the resistance of the resistance bridge in a response linear to the measuring pressure. These changes in resistance are converted by electronics built into the device into standardized electrical signals.
