The Capsuhelic gauge is designed to give fast, accurate indication of differential pressures. The gauge 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. Using the basic design of Dwyers time-proven Magnehelic gauge, the Capsuhelic gauge contains a simple, frictionless movement that permits full scale readings as low as 0.5 in H2O. 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 H2O. The diaphragm-actuated Capsuhelic gauge requires no filling liquid which might limit its outdoor applications. Zero and range adjustments are made from outside the gauge, and there is no need to disassemble the gauge in normal service. Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.
