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 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 WIKA CPC2000 portable low pressure controller is used in the areas of heating, ventilation, air conditioning, filtration, clean room, and medical technology as a calibrator or as highly-accurate measurement equipment and/or precise pressure transducer. The WIKA CPC2000 low-pressure controller is a mains or battery-operated pressure controller with internal, automatic pressure generation and pressure reference. The pressure generation is achieved using an integrated, electric pump, which makes a positive and/or negative pressure available on both the tube connections. As soon as the instrument is switched on, a zero-point adjustment is automatically carried out, so that a zero-point drift is eliminated. The subsequent preparation of a calibration requires only a few settings. First, using the MENU button, select one of the stored pressure units and the variable pressure change step in the range of 0 … 50 %. Then, once the full scale has been entered in Control Mode, the pressure can be easily increased or decreased by the defined level using the navigation buttons. To check whether the calibration assembly or the test item has a leak, the LEAK button can be used. With this, the pressure is locked into the test assembly and any pressure drop there might be, as well as the the time this takes, is measured and displayed. The CPC2000 has an RS-232 and USB interface, enabling communication and data exchange with a PC. WIKA-Cal calibration software is available for the CPC2000. WIKA-Cal also offers, over and above PC-supported calibration, the management of the calibration and instrument data in an SQL database. The accuracy of the instrument is certified by a factory calibration certificate.

The WIKA CPC8000-H Precision high-pressure controller is especially suited as a factory or working standard for the automatic testing or calibration of all types of high-pressure measuring instruments, due to its high accuracy and control stability. However, autofrettage applications or cyclic pressure-load tests are also ideal application areas, thanks to its robustness and reliability. For the supply to the controller, other than the voltage supply, only clean dry compressed air for the pneumatic control circuit is needed. As a pressure medium on the output side, hydraulic oil or water (or other media on request) can be used. The CPC8000-H consists of two components, the WIKA CPC8000-HC pressure controller and the WIKA CPC8000-HM hydraulic module with the reference pressure sensors. The hydraulic module is available in two versions, as a low-pressure version with a pressure range of 5 … 700 bar (75 … 10,000 psi) bar and a high-pressure version with a pressure range of 20 … 1,600 bar (290 … 23,000 psi) with each suitable reference pressure sensors. The complete system is available as a 19″ plug-in case or built into a 19″ rack. The sensors can be changed via the front of the hydraulic module, without having to dismantle the complete controller. Through its specialist technology, the desired pressure value from the controller is regulated quickly and simply. Maximum ease-of-use is achieved through a large touchscreen and simple and intuitive menu navigation. In addition, its easy operability is further supported by the availability of a large number of menu languages. On the large touchscreen, all necessary information such as current measured value and set point can be found on a single screen. Optionally, the measured values can be displayed in other pressure units additionally. The pressure controller can be remotely controlled via serial interfaces available. Through these, a wide range of emulation command sets for other pressure controllers are available.
