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.

The SIKA D-Ex digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA D-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. Tare / Zero-Function User-defined zero point setting at the push of a button makes offset adjustment easy and eliminates the need for tedious mechanical adjustment. Single-point adjustment allows the linear characteristic curve to be shifted in positive or negative direction over the entire measuring range. Selectable pressure units Another feature is the large selection of pressure units. Up to 6 different units are possible “ far more than any complicated dual-scale or multi-scale gauge can offer. The required display unit is selected directly on the digital pressure gauge and is indicated on display. No conversion necessary; the desired value can be read directly. Min / Max Displays and Peak function Experience shows that excess pressure and pressure peaks significantly higher than normal operating pressure occur at some measuring points. Min / max displays and fast peak value measurement cycles in digital pressure gauges assist in system analysis and allow peak values to be determined. This allows incorrect readings and violations of range limits to be detected and helps avoid damage to pressure systems. Preventive service is often less expensive than repairing or replacing defective instruments.

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.
