Dwyer Series 4000 Capsuhelic Differential Pressure Gages
The Dwyer Series 4000 Capsuhelic Differential Pressure Gages are designed to give fast, accurate indication of differential pressures. The Capsuhelic® Differential Pressure 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.
The Dwyer Series 4000 Capsuhelic Differential Pressure Gages may be used with hydrogen where pressures are less than 35 psi, and should be ordered with a Buna-N diaphragm. The Series 4000 Capsuhelic gages are available with optional forged brass housing for water or water based fluids, adjustable signal flags, NIST traceable calibration certificate, and red, green, mirrored or combination scale overlays.
