Due to their hygienic process connection, the WIKA 990.22, 990.52 and 990.53 diaphragm seals with sterile connection are particularly well suited for food production, pharmaceutical and biotechnology applications. The diaphragm seals can withstand the cleaning vapour temperatures occurring in the 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 WIKA CPC7000 pneumatic high-pressure controller always provides a suitable calibration solution on account of its accuracy class. Its outstanding control performance is particularly impressive thanks to special valve technology and the high-accuracy pressure sensor as a measuring unit. With this the WIKA CPC7000 pneumatic high-pressure controller is suitable as a factory or working standard for the testing or calibration of any type of pressure measuring instrument. The WIKA CPC7000 pneumatic high-pressure controller is available as a desktop instrument or as a 19″ rack-mounting kit. The sensors can be changed via the front, without having to take out the complete controller, e.g. out of a calibration rig (plug-and-play). The touchscreen, through its intuitive user interface, delivers ease of use. A large number of menu languages adds to its user-friendliness. In addition to specifying a specific pressure set point, either by entering it via touchscreen or sending it via a remote interface, the pressure can be changed in defined, programmable steps by using the STEP buttons. Moreover, the user can also easily create extensive test programs using the instrument menu. Depending on the application, the control rate can be set as a user-defined variable rate. The WIKA-Cal calibration software enables the convenient calibration of pressure measuring instruments and the generation of test certificates. Additionally, the instrument can also be remotely controlled using the serial command formats, the Mensor standard, SCPI or further optional command sets are available. There is an IEEE-488.2, RS-232, USB and an Ethernet interface for communication with other instruments, and thus the instrument can be integrated into existing systems.
