Beth-El’s differential pressure gauges indicate the differential pressure between two separate compartments within a shelter. The overpressure disparity between inside and outside the shelter can also be measured and the gauge is accurate within 2% of full scale, suiting precise needs.
Low, positive, negative (vacuum), or differential pressure, is quickly indicated on an analogue display using simple, frictionless movement. The gauge is designed to resist shock, vibration, and the effects of overpressure. Requiring no manometer fluid, the gauge does not experience problems with fluid evaporation, freezing, toxicity, or difficulties involving levelling.
Differential pressure transmitters by Beth-El are designed to measure pressure and to convert that pressure into a standard two-wire 4-20 mA signal. The transmitter is used in shelters to indicate the overpressure disparity between the shelter and the outside area or the differential pressure between different areas within a shelter.
The converted electrical signal can be transmitted to a computer terminal and the transmitter is guaranteed to be accurate within 2% of full scale, suiting precise needs. The transmitter’s metal housing is designed to resist shock, vibration, and the effects of overpressure.
