200 DPG

At a Glance

In the Hirlekar Precision Model 200 DPG, the movement of the piston is converted into appropriate calibrated rotary movement of the pointer through a magnetic connection. This type of piston model is used in applications where minor 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 recommended. 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.
