Differential pressure gauge, stainless steel Typ: DR20
Accuracy class 1,6
NG 100 and 160
without liquid filling
Service intended:
Measurement of pressure differential of 2 pressuresapplied. Suitable for gaseous and liquid, non-crystallizing media that will not obstruct the pressure system. Scale range must be selected in consideration of the highest static pressure applied. When ordering please state both, the static pressure applied and the pressure differential.
Fields of application:
● pneumatics, hydraulics
● heating and air conditioning technology
● Filter measurements
