Dwyer Capsuhelic Differential Pressure

The Capsuhelic gage is designed to give fast, accurate indication of differential pressures. 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.

Consult the attached pdf for full specifications. For technical assistance and a quote contact Teltherm.

The Capsuhelic's frictionless movement permits full scale readings as low as 0.5 in w.c. The pressure being measured is held within a capsule which is an integral part of the gauge. This containment of the pressure permits the use of the gauge on system pressures of up to 500 psig, even when differentials to be read are less than 0.1 in w.c.

The diaphragm-actuated Capsuhelic® gage requires no filling liquid which might limit its outdoor applications. Zero and range adjustments are made from outside the gauge.
Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Accuracy: ±3% of FS at 70°F (21.1°C). (±2% on 4000S models, ±4% on 4200, 4210, 4215, 4220, 4300, 4400, and 4500). Pressure Limits: -0.677 bar to 34.4 bar.
