Due to their hygienic process connection, the WIKA 990.24 sterile connection diaphragm seals are particularly well suited for food production. With this diaphragm seal, pressure measuring instruments can be integrated, dead-space free, into a pipeline using a VARINLINE® access unit or in tanks using a connecting flange for VARINLINE® access units. The diaphragm seals can withstand the cleaning vapour temperatures occurring in the CIP and SIP processes and thus ensure a sterile connection between the medium to be measured and the diaphragm seal. 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 electropolished.

The SIKA Type P digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA Type P digital pressure gauge can be used as a reference to explain the checking, adjustment and calibration of other pressure measurement devices directly on-site. Linearisation Multi-point adjustment can be performed if it is necessary to adjust the indicated values at different test points. Two-point adjustment is available for setting the zero point and slope of the measuring cell curve. Type P digital pressure gauges allow up to six offset values to be programmed to shift the characteristic curve to meet the most stringent customer expectations. 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.

The Danfoss KP pressure switches are used for regulating, monitoring and alarm systems in the industry. The KP pressure switches provide automatic limit protection or manual reset limit protection for pressure systems. The KP switches can be used with steam, air, gaseous and liquid media. The pressure switches are fitted with a single-pole changeover switch (SPDT). The position of the switch depends on the setting of the pressure switch and the pressure in the connector.
