P600 SERIES Low Pressure Diaphragm Gauge

Capsule type pressure gauges are applied to measure low and extremely low positive or negative pressure, in particular of gaseous fluid, and the use with liquid fluid is limited. the capsule is a modification of diaphragm element with two convoluted membranes, leakproof soldered around the circumference to form the capsule.

Low range may require several capslues which conbine to form a bellows-capsule. In general, the capsule is mounted vertically (in parallel with the dial) but for some special purpose instruments are different. The Ranges from 10" wc to 10psi are available in bottom or back connection.
