  • Stainless steel Schaeffer diaphragm gauge
  • Models ST / SCH
  • According to BS EN 837-3
  • Nominal sizes, 100 and 160 mm
  • Accuracy: Class 1,6
Construction:

These heavy duty industrial gauges, are manufactured with either a steel case and bezel, [black-epoxy coated], or with a stainless steel case and bezel. General construction is with a heavy duty fully adjustable rotary geared movement, in stainless steel with an upper flange and block in 304 ST.ST and a lower process chamber in 316 ST.ST. Mounting connection is either threaded or flanged.

Operation:

A convoluted diaphragm is clamped between two flanges. One side is pressurized by the process fluid, which deflects the diaphragm in proportion to the pressure. On the other side, a ball joint is fixed to the diaphragm and connected to the movement via a push rod, this transfers the diaphragm deflection to a pointer on the dial.
