Data sheet Pressure transducers DeltaFox DMU 21 D Version for differential pressure measurement

Benefits

LED display and open collector switching output
Turn down up to a maximum of 1:10 through customer
Min./Max. value storage
Housing can be rotated by 330° and pressure connections by 300°

Application

For electronic differential pressure measurement which requires a local display in addition to the analogue output, for example for monitoring filters and fans. The differential pressure transducer can be used with all liquid and gaseous, corrosive media which a not highly viscous and which do not crystallize.

Description

The DeltaFox^®DMU 21 D pressure transducers feature two oil-immersed piezo-resistive stainless steel measuring cells and a 4-digit, red LED display. When pressure is applied, the pressure difference between the positive pressure side and the negative pressure side is converted into a current signal which is proportional to the differential pressure. A menu and two keys allow for displaying the measured values and for configuring the individual parameters.
