Our pressure gauges (mechanical pressure measuring instruments) 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. The pressure gauges cover scale ranges from 0 … 0.5 mbar to 0 … 7,000 bar and indication accuracies of up to 0.1 %. For the various requirements in industrial and process instrumentation there are pressure elements from copper alloys, stainless steel or special materials available.

A pressure sensor (often also referred to as a pressure transmitter) converts the physical quantity 'pressure' into an industry-standard signal. Our portfolio covers a wide spectrum of pressure sensors for general industrial applications. For refrigeration and air-conditioning applications, for the food industry, mobile working machines, medical gases and the semiconductor industry, special versions are available.

The pressure sensors offer accuracies from 0.05 %, measuring ranges from 0.05 bar up to 15,000 bar, digital interfaces such as CANopen and IO-Link and also various international approvals, including for hazardous areas.

For each application the right pressure switch

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.

Pressure switches are used in a variety of industrial and technical processes − in the broad WIKA selection you will find the right version for each application.

Diaphragm seals

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. The optimal diaphragm seal designs, materials and filling media are available for each application.

Via cocks, shut-off valves, valve manifolds or monoflanges, pressure measuring instruments can be securely separated from the process during commissioning, maintenance or calibration. Protective devices, such as syphons, overpressure protectors and snubbers, increase the service life and extend the application spectrum of pressure measuring instruments. Alongside the extensive selection of instrumentation valves and accessories, WIKA also offers qualified assembly of different individual components into a complete measuring arrangement (“hook-up”).

A digital pressure gauge displays the acting pressure in an integrated digital display. WIKA offers digital pressure gauges for general industrial applications and also for use in the field of testing and calibration. The indicator cases of our digital pressure gauges are rotatable if required and thus always ensure a good readability. In addition, intrinsically safe versions and instruments with wireless interface are available.

Process transmitters differentiate themselves from pressure sensors through their increased range of functionality: They feature integrated displays, offer high measuring accuracies and freely scalable measuring ranges, communicate via digital bus signals and can be delivered with a multitude of case variants and also worldwide Ex approvals. Through connection to diaphragm seals, they are also suitable for the harshest operating conditions.

Adapters are, together with seals, used for the installation of pressure measuring instruments, stopcocks, shut-off valves, syphons, snubbers and other accessory components. Protection caps protect the pressure gauges from shocks, impacts, corrosion and weathering effects. Instrument mounting brackets serve for the wall or pipe mounting of pressure measuring instruments.
