The WIKA E-10 and E-11 flameproof pressure transmitters have been designed specifically for the high demands of industrial oil and gas applications. These pressure transmitters can be delivered with various analogue signals from 4 … 20 mA to a low-power version with DC 1 … 5 V. They feature exceptionally high resistance to vibration, pressure spikes and moisture ingress. Furthermore, these pressure transmitters fulfil IP 67 (NEMA 4x) ingress protection. On each instrument, comprehensive quality control and calibration is performed, so that an accuracy of 0.5 % can be ensured. Temperature compensation guarantees accuracy and long-term stability, even with strong fluctuations in the ambient temperature. The WIKA E-10 and E-11 are suitable for sour gas applications and feature particularly high resistance against sulphide stress cracking when in contact with sulphurous gases. The pressure transmitters are approved as œexplosion-proof for class I, II, III, div. 1 hazardous areas to FM and CSA as well as œflameproof for II 2 G Ex d II C to ATEX.

Wherever very low pressures have to be indicated locally and, at the same time, a signal transmission to the central control or remote centre is desired, the WIKA PGT63HP.100 / PGT63HP.160 pressure gauge intelliGAUGE® (patent, property right: e.g. DE 202007019025) can be used. The robust capsule measuring system has an overload safety of up to 50 times the full-scale value. An electronic angle encoder, proven in safety-critical automotive applications, determines the position of the pointer shaft “ it is a non-contact sensor and therefore completely free from wear and friction. From this, the electrical output signal proportional to the pressure, e.g. 4 … 20 mA, is produced. The measuring span (electrical output signal) is adjusted automatically along with the mechanical display, i.e. the scale over the full display range corresponds to 4 … 20 mA. The electrical zero point can also be set manually. The electronic WIKA sensor, integrated into the high-quality capsule pressure gauge, combines the advantages of electrical signal transmission with a local mechanical display that remains readable during a power failure. An additional measuring point for mechanical pressure display can thus be saved.
