Differential Pressure Gauges
with vertical diaphragm /
measuring membrane
Class 2.5 NCS 100 ModelDiPsPH
Application
Differential pressure gauges model DiPsPH are suitable for overpressure, underpressure- and differential pressure measurement in the field of industrial measurement technique.
Typical special applications are differential pressure measurements between flow and return flow in heating systems, monitoring of filters, aerators and compressors.
Measuring units and measuring chambers are available as different materials. An adaption of the instruments to different requirements is possible with this.
Construction and Measuring Principle
A robust, non-sensitive membrane, resp. for 10 bar and above a diaphragm measuring system is provided as measuring cell.
In rest position the strengths, that effect the measuring membrane/ diaphragm (5) are equalised both-sided. An one-sided strength, which switches the measuring membrane/diaphragm in one direction up to the compensation of the elastic force, arises by the measured pressure or differential pressure.
If overload occurs, the measuring membrane/diaphragm reinforces against metallic installation surfaces. A centrically ordered ram transfers the motion of the measuring membrane/diaphragm on to the movement.
Nominal case size 100 (4")
Accuracy class 2.5 according to EN 837-3
