The WIKA E-10 and E-11 explosion-proof pressure transmitters are engineered to meet Class I, Division 1 explosion-proof protection for installation in hazardous environments. Featuring rugged design and NEMA 4X (IP67) ingress protection, the E-10 and E-11 have been specifically designed to meet the durability and performance requirements of oil and gas pressure monitoring applications.
The WIKA E-10 and E-11 pressure transmitters feature an industry standard 4-20mA 2-wire or 1-5V 3-wire low power signal output. They are extremely resistant to pressure spikes, vibration and moisture intrusion. NACE MR- 01-75 compliant wetted parts provides extra resistance against sulfide stress cracking when exposed to media containing sulfur. Both are available with a factory sealed epoxy flying lead assembly for easier installation.
The E-10 features an NPT process connection with an all-welded stainless steel measuring cell for media compatibility while the E-11 features a flush diaphragm process connection. This flat sensing surface is specifically designed for the measurement of viscous fluids or media containing solids that may clog the NPT process connection. There are no internal soft sealing materials that may react with the media or deteriorate over time.
Each transmitter undergoes extensive quality control testing and calibration to achieve a linearity of ±0.25% full scale. In addition, each pressure transmitter is temperature compensated to assure accuracy and long-term stability even when exposed to severe ambient temperature variations.
