PHB-A
Suitable for Pressure Measurement of LPG/LNG Tanks and Gas or Steam Turbines
PHB-A series is designed for pressure measurement from low to high temperatures. The sensor surface is made by stainless steel diaphragm and inert gas is filled in to increase reliability.
?? Usable at both high and low temperatures
?? Corrosion resistant
?? Hermetically-sealed structure with inert gas filled in
?? Highly reliable

* Do not use PHB-A-20MP to PHB-A-50MP for endurace/fatigue tests.
* Avoid using for a long-term measurement of gas pressure if much importance is attached to the stability of output in a minute range. For such application, we can manufacture models with no air vent.
