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.
The comprehensive range of accessories comprises valves and protective devices (e.g. pressure gauge valves, pressure gauge cocks and pressure gauge syphons), mounting accessories and electrical accessories.
Our dial thermometers work on the bimetal, expansion or gas actuation principle. This enables scale ranges of -200 to +700 °C in different class accuracies, response times and resilience to environmental influences.
For demanding operating conditions, the thermowells / protection tubes from WIKA are available both in solid-machined and fabricated designs. The variants offered differ mainly in their designs; with flanges, with threads or for welding. Furthermore, thermowells are available in Van Stone design and with connections for sanitary applications.
The range of services comprises the calibration of measuring instruments in WIKA's own accredited DKD/DAkkS calibration laboratories and a mobile service to calibrate your instruments on site.
