Pressure Ranges
0-0.16 to 0-2 bar
0-2.4 to 0-30 psi
In the Hirlekar Precision Model DX 20, the movement of the diaphragm, hence that of the corresponding piston magnet, 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 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.
Model DX 20 is also available in a bar/psi dual scale.
