Diaphragm seal pressure gauges

What is a diaphragm seal?

A diaphragm seal is a stretchy covering that seals and separates an enclosure. The flexible character of this seal enables pressure results to cross the hurdle, but not the objects being contained. General uses for diaphragm seals are to defend pressure gauges from the liquid whose pressure is being calculated.

What is a diaphragm seal pressure gauge ?

A diaphragm seal pressure gauge is a tool consisting of a diaphragm firmly clamped or welded between two appropriate flanges to put off leakage of gas or liquid. The diaphragm is a separating membrane or thin divider that operates as a barrier to a gas or liquid that may block or decay the sensing element of a pressure gauge. A diaphragm seal pressure gauge is suitable for the measurement of high viscosity liquid, highly corrosive liquid, fluid which includes solid materials or fluid to be effortlessly solidified.

Features

Since the high-rust resistant diaphragm can be employed at the pressure receiving part, the diaphragm seal pressure gauge can be employed for the measurement of highly acidic measuring liquid.

For a diaphragm seal pressure gauge in which a diaphragm is fixed by welding, the diaphragm surface can be effortlessly cleaned by loosening the casing locks.

A zero-adjusting needle has been used in a diaphragm seal pressure gauge, so necessary calibration owing to errors of elevation, temperature, etc. can be effortlessly preformed.

By means of the application of a welded diaphragm the application for seepage of the filling fluid has been reduced.

Dampener

When the diaphragm seal pressure gauge is subjected to surge pressure or high pulsating pressure, it is better to install the dampener to defend the gauge. The dampener includes a variable throttle, which can be attuned consistent with pressure difference. When installed in a diaphragm seal pressure gauge, the dampener chokes only the filled fluid, eliminating the hazard of clogging attributable to foreign matter. Additionally, the stable throttling effect is guaranteed, due to the outstanding feature of filling fluid where viscosity barely changes with temperature.

Radiation tube

For a middle heat diaphragm seal pressure gauge or direct mounting type, or when the heat of sensing part turn out to be 180g or more, it is safe to use the radiation tube to lessen the power of temperature on the warning part.
