370 DGC

At a Glance

In the Hirlekar Precision Model 370 DGC, the movement of the convoluted 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.
In case of condensation: New EP series engineering polymer case is a standard case with this product. In operating condition with frequent temperature fluctuations, condensation may occur on the glass affecting visibility. Hirlekar Precision’s EP Series Engineering polymer cases can be easily opened and cleaned on site.
