The WIKA 990.40 diaphragm seal with threaded connection in threaded design is suitable for versatile application areas. A replacement of the lower body is possible without modifications on the diaphragm seal system. With this diaphragm seal, low-pressure ranges can be covered ” the large diameter of the diaphragm affects a lower deviation at the measuring instrument when the temperature changes. Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection, for high temperatures via a cooling element or via a flexible capillary. For the material selection, WIKA offers a variety of solutions, in which the upper body of the diaphragm seal and the wetted parts can be made of identical or different materials. The wetted parts can, as an alternative, be coated.

Thanks to its flush process connection, the WIKA 990.17 diaphragm seal is optimally suited for installation in storage tanks. With a suitable welding flange, this diaphragm seal can be integrated into any type of tank or vessel. Level measurement with diaphragm seals also works with media that, due to the process, are under pressure and have high or low viscosity. The WIKA 990.17 diaphragm seal is particularly suitable for CIP cleaning processes as it meets the requirements for elevated temperatures and chemical resistance to cleaning solutions. Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection, for high temperatures via a cooling element or via a flexible capillary. For the material selection, WIKA offers a variety of solutions, in which the diaphragm seal and the wetted parts can be made of identical or different materials. The wetted parts can, as an alternative, be electropolished.

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 L-Ex digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA L-Ex digital pressure gauge can be used as a reference to explain the checking, adjustment and calibration of other pressure measurement devices directly on-site. High accuracy in the signal acquisition is achieved by using high-performance measuring cells with electronic linearisation of the characteristic curve. Suitable instruments are available for a wide variety of measurement tasks. Ease of use is assured by innovative design and advanced technology. All essential functions for everyday use can be selected conveniently at the press of a button. Excellent protection against dust and moisture is provided by a membrane keypad or rubber buttons. Integrated supplementary functions make our digital pressure gauges true all-rounders. 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. A 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.
