Safety Pressure Gauges “Solid-Front”

PBPSF115

These Solid-Front instruments are built in accordance with safety specifications of ASME B40.1.
The safety construction consists of a stainless steel solid-front safety cell placed behind the scale, which welding to socket gives to instrument an exceptional strength. Whenever, due to leaks, the internal pressure is created or the elastic element is broken the safety cell protects the front and sides, meanwhile the blow out back is released from the case. These instruments are designed for use in food, beverage, pharmaceutical, cryogenics, chemical and petrochemical processing industries, and in conventional and nuclear power plants. They are built to resist the most severe operating conditions created by the ambient environment and the process medium.
