Differential pressure switch
The Dietz Model 190 differential pressure switch with digital readout from The Henry G. Dietz Co. was designed for cleanroom applications to measure and control low differential air pressures. The Model 190 has an accuracy of 0.5 percent and is available in differential pressure ranges down to 0.5-in. W.C. with a resolution of 0.001-in. W.C. This model features repeatability, low hysteresis and operation over a broad temperature range.
It can be used as a switch, gauge, switch/gauge, manometer, air filter gauge, velocity air pressure gauge, flowmeter and as a transducer. It can detect low air velocities and low differential pressure to determine the ventilation of cleanrooms.
