Description

Technical Field

[0002] Electrical contact pressure gauges are widely used in petroleum, chemical, metallurgical, power plant, and machinery industries, or in the installation of electromechanical equipment, to measure the pressure of various non-explosive fluid media. Typically, when used with appropriate electrical components (such as relays and frequency converters), the instrument can automatically control and send signals (alarms) for various gaseous and liquid media under measured (controlled) pressure. An electrical contact pressure gauge consists of a measuring system, an indicating system, a magnetically assisted electrical contact device, a housing, an adjusting device, and a junction box (plug socket). General electrical contact pressure gauges are used to measure the positive and negative pressure of gaseous and liquid media that do not corrode copper and copper alloys. Stainless steel electrical contact pressure gauges are used to measure the positive and negative pressure of gaseous and liquid media that do not corrode stainless steel and send a signal when the pressure reaches a predetermined value, connecting the control circuit to achieve automatic control and alarm purposes. A molten diaphragm electrical contact pressure gauge is a pressure measuring device that combines molten diaphragm and electrical contact technology.
