The WIKA 990.31 diaphragm seal with threaded connection in a plastic version is suitable for versatile application areas in the water supply and wastewater treatment industries. Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection or a flexible capillary. The WIKA 990.31 diaphragm seal is used successfully in chemical plant construction, electroplating and wastewater treatment applications.

The Trafag EXPD 920/924/932 ex differential pressostat electromechanical pressure switches provide high vibration resistance and switch point precision in combination with an extremely robust and durable design. This results in switches that can be operated for decades without requiring maintenance, even under harsh conditions. Various designs with bellows, membrane and piston sensors cover a wide variety of pressure ranges, media and load profiles for many different applications.

The SIKA Type J digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA Type J digital pressure gauge can be used as a reference to explain the checking, adjustment and calibration of other pressure measurement devices directly on-site. PC connection and software Many digital pressure gauges have a serial interface port to allow measurement values and stored data to be transferred directly to a PC and documented. An inexpensive measurement data acquisition system can easily be assembled with suitable software and an interface converter. Processes can be readily monitored and analysed using the recorded and visualised measurements, and all data can be exported using standard programs such as Microsoft Excel. Remote control is also possible. Various software packages with extensive recording and display functions, logger and alarm evaluation as well as for calibration are available. Analogue output An electrical output signal enables remote display on a control console or in a control room as well as the connection of external recorders and indicating instruments. Relay output Digital pressure gauges allow limit contacts to be closed even at low pressures. There is no need for high actuation forces for magnetic spring or inductive contacts, which makes it easier to signal critical equipment conditions and perform supplementary control tasks.
