About Capsuhelic Differential Pressure Gage

Capsuhelic Differential Pressure Gage

Series 4000 Capsuhelic® Differential Pressure Gage

Measures Pressure, Vacuum or Differential, Suitable for Internal Pressures to 500 psig

The SERIES 4000 Capsuhelic® Gage is designed to give fast, accurate indication of differential pressures. The gage may be used as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and many other applications involving pressure, vacuum or differential pressure. The pressure being measured is held within a capsule which is an integral part of the gage. This containment of the pressure permits the use of the gage on system pressures of up to 500 psig, even when differentials to be read are less than 0.1 in w.c.

Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Product Applications

Fluid flow
Liquid storage tanks
Filter pressure drops
Vacuum or differential pressure
