Pressure Ranges
0-0.075 to 0-4 bar
0-1 to 0-60 psi
In the Hirlekar Precision Model 320 DGC, the movement of the diaphragm is converted into appropriate calibrated rotary movement of the pointer through a magnetic connection. This type of diaphragm model is used in applications where no migration of the media from high pressure side (HP) to low pressure side (LP) is permitted.
