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 SIKA E2 digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA E2 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 a 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 a 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 SIKA Type J digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA Type J digital pressure gauge can be used as a reference to explain the checking, adjustment and calibration of other pressure measurement devices directly on-site. 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 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.
