Data sheet process monitoring device PUC 28 / PUC 28 K - 2

Measurement of differential pressure is useful in a broad range of applications. It is used in ventilation and air-conditioning technology but also in many areas of air handling process technology. The next pages show a number of these. You can find more information about our pressure sensor technology on p. 6. halstrup-walcher offers a wide range of products for stationary measurement of differential pressure: Process monitoring for clean-rooms (Pa, ° C, % rH), with stainless steel front Process monitoring panel aluminium, anodised (optional: with calibration port) (Pa, ° C, % rH) High...
