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.

The mechanical WIKA PSM-700 pressure switch is designed for control and monitoring applications. The measuring element is a fully welded bellow made of stainless steel 316L. This corrosion-resistant pressure switch is suitable for a broad range of media used in the process industry. The case consists of a high-grade aluminium alloy with which the pressure switch can withstand the harsh operating conditions of the process industry. The WIKA PSM-700 pressure switch is equipped with UL listed micro switches to ensure high endurance with the durable operation and long service life. The WIKA PSM-700 pressure switch has a high switch point repeatability of 0.5 %, which enables reliable switching. Adjustable switch differential to a wide range of up to 60 % of the setting range to realise flexible on/off controls This wide setting range is often needed for the on/off control mode of cyclic applications. The switch point can be specified on site. With the tamper-proofing, which is available as an option, unauthorised adjustment of the switch point can be prevented.
