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 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.
