Description
HAWK type 15L and 15B are solid front process gauges supplied with an Aluminum front flange safety case with a black enamel finish. The stainless steel polished ring makes these gauge well suited for panel board applications. The front screw lets users open the window and permits easy panel installation. 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

Specifications
Operating
Steady: 100%*full scale value
Pulsation: 90%*full scale value
Sudden: 130%*full scale value
The appropriate operating range falls in the middle half of the gauge (25%to 75% of full scale). If you choose the unsuitable range, the fatigue of bourdon tube may be resulted. HAWK Supplies a wide selection of range from vacuum to 20,000 PSI including compound range.
