The WIKA 990.10 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, high pressure ranges up to 250 bar can be covered. Compared to the WIKA 990.40 diaphragm seal, higher pressure ranges can be covered (smaller diameter of the diaphragm). 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 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 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 CPG-KITP pneumatic service kit is the ideal tool for the pneumatic testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements or for the setting of pressure switches. These and other tests can take place quickly and reliably in the laboratory or workshop, or on-site at the measuring point. With the service kit, service and maintenance are more complete, safer and more flexible. The kit is high-quality finish, handy and robust and is also suitable for service use. Components The service kit consists of a pneumatic hand test pump for the generation of defined test pressure and also a highly accurate WIKA CPG1500 precision digital pressure gauge as a reference instrument. Air is used as the pressure medium. Various connection adapters are also available in the test case. All components are carefully stowed in the case and protected for in-house transport. Simple function If one connects the test item and the WIKA CPG1500 precision digital pressure gauge to the test pump, on actuating the pump, the same pressure will act on both instruments. Using the fine adjustment valve, the test pressure is set precisely. By comparison of the two measured values at any given pressure value, a check of the accuracy and/or adjustment of the pressure measuring instrument under test can be carried out. WIKA-CAL software The collected data from the data logger of the digital pressure gauge can be transmitted wirelessly to the WIKA-CAL calibration software for further evaluation.
