Electric contact pressure gauges MANOTHERM PCh, PChG, PChOe, PSChG, etc.

Electrocontact pressure gauges or so-called signaling pressure gauges have the ability to adjust the pressure of the measured medium, due to the presence of an electrocontact mechanism. They are available with several versions of the contact group. Designed to measure the excess and vacuum pressure of non-crystallizing liquids, steam and gas, non-aggressive to the materials of parts in contact with the measured medium, and discrete control of the electrical circuits of auxiliary and regulating devices (if the setpoint value is exceeded, the electrical circuit is closed or opened). Explosion-proof versions of electric contact pressure gauges are available. The explosion protection of the devices is ensured by the fulfillment of the general technical requirements for explosion-proof electrical equipment.

Models: PCh, PChOe, PSCh, PSChOe.

• Electric contact pressure gauges (signaling pressure gauges). Technical description.

Absolute pressure gauges. They have a stainless steel case with a diameter of 100 or 160 mm with a bayonet ring. Designed to work with liquid and gaseous media to be measured. Open flange pressure gauges are also used for viscous measuring media and media containing solid particles. The devices are equipped with vacuum chambers, separated from the process by a membrane, and allowing to measure the absolute pressure. A duratherm plate spring serves as a membrane, the difference of which is minimal hysteresis and a long service life.

Models: APCh, APSChG.
