Fire & Smoke Detection with MSR Germany Sensor.

Gas Alarm offers world-class solutions and products for earliest and accurate fire and smoke monitoring, without giving any false alarms. These products offer warning signals better and earlier than costliest system like VESDA, optical sensors etc.
Very Early Fire & Smoke Detector, Gas Alarm offer one of the best smoke & fire detector which can be installed at any environment eg. coal mines, flour mills, pharma, clean rooms, oil & gas, etc. Early Fire detector / transmitter (VEFSA) is designed for detection of earliest sign of smoke & fire, and hence thereby offering better warning detection system, better than VESDA. Using unique detection technology and method, VEFSA offer best fire & smoke detection, without false alarm. These can be implemented at any location with quite easy. VEFSA is compatible for integration to any fire panel and alarm system, be to Siemens, Honeywell, GE etc. VEFSA works in environment and application where none of the conventional smoke & fire detection can work. VEFSA, though being more effective than some of the expensive solutions, it even more easy to implement and integrate, without having much design knowledge.

As VEFSA provide earliest signs of smoke & fire, it buy the critical time needed to investigate an alarm and initiate an appropriate response to prevent injury, property damage or business disruption. VEFSA offer various levels of integrity monitoring to ensure an alert is raised at any time, depending upon criticality of the application and environment. This is not the case with passive devices that are generally only electrically monitored with no ability to determine if smoke can actually reach the detection element. VEFSA offer dual level of alarms which are configurable. This VEFSA to provide very early warning of an event, prompting investigation at the earliest smouldering stage of a fire when it is easily addressed. Other alarm levels may be configured to provide fire alarm inputs to fire systems as well as releasing suppression systems. VEFSa alarm sensitivities are configurable and can be programmed to levels ranging from thousands of times more sensitive than a conventional detector, to much less sensitive.

VEFSA can be implemented across a wide (all) range of industries and applications, with no effect of dust, moisture, vibration, temperature, weather, pressure etc:

FISCHER – DA55 – ABSOLUTE PRESSURE GUAGE

Product Description

Gas Warning Systems for Maximum Safety

ALVI Automation in association with MSR-Electronic Germany  provides reliable sensors, controllers and warning devices for refrigeration systems. The product line PolyGard®2 ensures reliable monitoring of leakages at all times and thus protects not only the health of persons but also the operation of the refrigeration systems. The simple Plug & Play sensor technology (X-Change) also allows you to save time and costs for maintenance significantly. The sensors are available for all common refrigerants.

Advantages when using the certified gas warning systems from MSR-Electronic:

 Compliant with EN 378-1 and many more

 SIL2 compliant according to IEC 61508

 Suitable for large and small systems

 The X-Change exchangeable sensor makes calibration of the sensors easier

 Alarm thresholds and interfaces freely selectable

The door-entry modules provide maximum safety in addition: If the gas concentration increases in closed buildings, for example in cooling rooms, the doors can only be opened in one direction: from the inside to the outside. This ensures that people can only move out of the hazardous area, but they can never move in.

The Bavarian company MSR-Electronic, headquartered in Pocking, develops and produces perfectly matched sensors, controllers and warning devices, which can be combined in many ways into high quality gas warning systems. Optimum protection for people and installation is thus ensured in enclosed areas in critical situations. Due to the individual configuration and the flexible integration, solutions from MSR Electronic are used worldwide in a variety of applications.

On our homepage (www.alviautomation.com) you will find details about all products.

Industrial Gas Detection for Safe Protection in Hazardous Conditions

Most of the manufacturing industries  in the world, be it food & beverage production, mining or automotive, pharma industry, Oil & Gas, Refineries and Petroleum  industries  use processes that can produce dangerous levels of poisonous gases. Some gases are  easily recognized by  their pungent smell, but some are odourless and tasteless, making them particularly difficult to identify. All  around the world, a large number of people die every year as a result of inhaling toxic gases encountered in their various fields of operations and several explosions have occurred due to combustible gas leaks. Basically there are three hazard categories:

• Combustible Gases: Dangers of explosion
• Toxic Gases: Danger of poisoning
• Oxygen: Danger of suffocation due to Oxygen deficiency or fire hazard due to Excess Oxygen

Wherever such hazardous gases are stored, bottled, processed or transported, safety is at risk.

The dangers posed by such toxic and combustible gases are very significant hence there is a  need for gas detection  to keep the work-place and the workers safe.

Custom Built FISCHER Differential Pressure Switch model no DS1302VAYYYD0064

ALVI  Automation – India (http://www.alviautomation.com) offers Custom Built FISCHER/Germany Differential Pressure Switch model no DS1302VAYYYD0064

Principles of Operation

This differential pressure instrument is based on a rugged and uncomplicated diaphragm movement, suitable for overpressure, partial vacuum and differential pressure measurements. The system’s operating principle is identical for all applications of this type. In a state of balance, forces of springs on both sides of diaphragm are balanced. The Pressure or differential pressure to be measured creates an unbalanced force of springs for measuring range until a new balance is reached. When subjected to excessive pressure, the diaphragm rests on metal supporting plates. A centre-mounted tappet transfers motion of the diaphragm system to indicator movement and to initiating elements of the microswitches.

Indoor Air Quality Sensor transmitter -IAQ

The most important aspect of air quality in closed rooms like homes, schools, recreational buildings, restaurants, public buildings, offices is the purity of air.

Stale or impure air reduces well-being and impairs productivity or efficiency of work procedures and production processes. The quality of air inside a building depends on the concentrations of contaminants and it is essential to monitor indoor air quality (IAQ) for occupant’s health, productivity and comfort.

Level Measurement for Fuel Oil Tank

Why measure Fuel Oil Level?

Precise control of level measurement for fuel oil tank is crucial in many applications. In process plants fuel oil is delivered to the storage tanks and then is transferred to process or may be a smaller day tank. It is very important to know the fuel oil level either in the storage tank or in a day tank for day-to-day operations of the plants.

The main aspect for level measurement for fuel oil tank is to keep track of inventory in terms of volume. Keeping good control over your inventory has become increasingly important over the last several years. Level measurement is one key component for reliable and accurate inventory control. Many processes require a steady supply of inputs . A storage tank between the supply and process acts as a buffer and maintains steady and consistent supply for the process. For a maximum process efficiency the tanks need to be filled to full capacity at all times.
