E-10 Explosion-Proof Pressure Transmitter Maintains Control and Maximizes Performance

Improved monitoring and continuous control of wellheads is a critical concern in energy production and transport industries. Monitoring of oil and gas wellheads to improve well production output has become standard procedure. WIKA has developed a product specifically with a closed-loop automated production capability to help.

The WIKA E-10 explosion-proof pressure transmitter is designed for applications in the oil and gas production industry including casing and tubing pressure, wellhead monitoring, refining, pipeline transport, and natural gas compressors. The explosion-proof pressure transmitter works on the principle of containment. The pressure transmitter is enclosed in a housing that is designed to contain, control, cool, and vent any possible ignition.

WIKA’s explosion-proof pressure transmitters contain any explosions within an enclosure to prevent electrical or thermal energy from reaching the volatile atmosphere. Several methods of explosion-proofing are available, including filling the containment enclosure with oil or surrounding the electrical apparatus with molding resin or potting compound.

In the petrochemical and process industries, a high temperature pressure transmitter or pressure transducer may be subjected to uncompromising environmental conditions such as aggressive media, temperature extremes, vibration, and pulsation. The E-10 is consistently reliable, making it ideal for detecting problems or abnormal conditions in the network of tanks, vessels, pipes, and control systems that must be monitored and maintained within optimum operating tolerances.

E-10 Pressure Transmitter Features

• FM-approved explosion proof for Class I Division 1 hazardous locations
• Available with 4…20 mA, 2-wire or 1…5 V, 3-wire output signals
• Engineered to withstand harsh environments
• NACE MR-01-75 compliant
• NEMA 4X (IP67) ingress protection
• Can be retrofitted to many existing oil and gas applications

E-10 Approved for Installation in Hazardous Areas

• FM approved
• CSA certified

The E-10 pressure transmitter features an NPT process connection with an all-welded stainless steel measuring cell for media compatibility, specifically designed with no internal soft sealing materials that may react with the media or deteriorate over time.

The pressure transmitter is FM-approved for Class I, Division 1 explosion-proof protection for installation in hazardous environments. Each pressure transmitter undergoes extensive quality control testing and calibration to achieve a linearity of < 0.2% full scale. In addition, each high temperature pressure transmitter is temperature compensated to assure accuracy and long-term stability even when exposed to severe ambient temperature variations.
