描述
HAWK Diaphragm Pressure Gauge use a diaphragm as its sensing element which can be welded or bonded or clamped to the upper and lower housing.The diaphragm deflects upward or downward when subjecting or release to pressure.This variation is converted into the rotary motion of the pointer by a movement and a connecting rod.It is a alternative to a liquid filled actuated system ( pressure gauge and diaphragm seal assembly ).
HAWK type 81L diaphragm process gauges with phenolic case are widely used for petrochemical and chemical processing industries.There is a solid wall between pressure sensing element and the window.This design provides better safety for monitoring the gauges in the event of the gauge failure.
