Differential Pressure Gauges and Pressure Sensors

Cost Effective and High Performing Pressure Gauges and Sensors by Beth-El Industries

Beth El Industries' differential pressure gauges show the differential pressure between two rooms. They are used in shelters to indicate the overpressure disparity between the shelter and the outside area or the differential pressure between the different areas inside the shelter.

Guaranteed to be accurate within 2% (of full scale), Beth-El is able to suit precise customer needs. Low air pressure, positive, negative (vacuum), or differential, are quickly indicated on an analogue display, using simple, frictionless movement. Beth-El pressure gauges are designed to resist shock, vibration, and overpressure and can withstand a blast pressure of 40 bar at an impulse of 70 bar ms. The lack of manometer fluid alleviates the problems of fluid evaporation, freezing, toxicity, or levelling difficulties. The gauges are tested and certified for compliance to the Israeli and Singaporean standards.

Beth-El's differential pressure transmitter is designed to measure pressure and to convert that measurement into a standard two-wire 4-20 mA signal. It is used in shelters to indicate the overpressure disparity between the shelter and the outside area or the differential pressure between the different areas inside the shelter. The converted electrical signal can be transmitted to a computer terminal.

The pressure sensor is a very important element of the Beth-El NBC protection system for vehicles and also is designed for the air cleaner system for vehicles. It monitors the system and provides a signal of the achieved overpressure in the protected space or the barrier / safety filter and gives an alarm / warning when set minimum values are not present. It provides an indirect answer that the NBC system or air cleaner is working and the systems are operating properly. The pressure sensor design was created to meet the harshest MIL working conditions and to provide continuous data.
