Our mechanical pressure gauges for gauge, absolute and differential pressure have been proven millions of times over. For the optimal solution for the widest range of applications, there is a choice of measuring systems in Bourdon tube, diaphragm element and capsule element technologies. For the various requirements in industrial and process instrumentation there are pressure elements from copper alloys, stainless steel or special materials.

A pressure transmitter converts the physical quantity 'pressure' into an industry-standard signal. Our portfolio covers a wide spectrum of pressure transmitters: for refrigeration and air-conditioning applications, for the food industry, mobile working machines, medical gases and the semiconductor industry, special versions are available

A pressure switch opens or closes a corresponding switch contact as soon as a preset pressure is reached. Depending on the requirement, pressure switches are used with mechanical or electrical switch contacts, with or without displays and with various setting possibilities.

Wherever the process pressure has to be indicated locally and, at the same time, limit values must be monitored, or signal must be transmitted, mechatronic pressure gauges are the perfect solution! 

WIKA diaphragm seals (often also referred to as chemical seals), mounted with pressure gauges, process transmitters, pressure switches etc., are recognised and valued internationally for the most difficult of measuring tasks. By using diaphragm seals, the measuring instruments can be used at extreme temperatures from -90 to +400 °C and with aggressive, corrosive, heterogeneous, abrasive, highly viscous or toxic media

For safe operation of instrument and to improve performance of the instrument, many WIKA accessories are available to serve your application.
