Differential pressure switch

DDS 50/1

Pressure sensors

Description
Technical data
This differential pressure switch measures the difference in pressure
between main feed lines 1 and 2 A signal is sent to the electrical Function principle differential pressure switch
control unit when a differential pressure of p = 50 bar is reached Operating temperature –25 to +80 °C, –13 to +176 °F
Operating pressure
max 400 bar, max 5 800 psi
This non-adjustable differential pressure provides a high degree of Differential pressure 50 bar, 725 psi
