From 400 mbar depending on diameter of diaphragm, -1...1000 bar - -1...3 bar__0...700 bar

The WIKA 990.26 diaphragm seal is ideally suited for applications with small process connections. Due to the internal diaphragm, low measuring ranges can be realised ” 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. Applications Chemical process industry Petrochemical industry Suitable for corrosive, highly viscous, crystallising or hot pressure media For small flanged process connections

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 SIKA D2 digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA D2 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.

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. Display The large illuminated digital local display shows the measured pressure and indicates the current status of the digital pressure gauge, even under poor lighting conditions. This eliminates the difficult task of reading a dial gauge and avoiding parallax errors. Needle jitter due to vibration or pressure fluctuations is eliminated. Display damping or averaging can be configured directly using display filters. This ensures easy, tireless readout. Protection class High IP protection classes (IP67 (front) / IP67) are available to minimise dust and water sensitivity. Rugged, impact-resistant digital pressure gauges are fitted with rubber caps for protection during transport and field use. Battery operation / Auto-Off Power is supplied by long-life batteries (ordinary or rechargeable). An external AC adapter can also be used. To increase battery operating time, a Programmable Auto-Off function switches off the power to the instrument after prolonged inactivity. The electronics are designed for extremely low power consumption, which enables battery life of significantly more than 1500 hours.
