E-10 (E-11) Hazardous Area Pressure Transmitter
Brand: WIKA Alexander Wiegand SE & Co. KGThe E-10 and E-11 explosion-proof pressure transmitters are specifically designed to meet the durability and performance requirements of oil and gas pressure monitoring applications.
These pressure transmitters feature an industry standard 4-20 mA 2-wire or 1-5V 3-wire low power signal output and NEMA 4X (IP67) ingress protection.
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 sulphur. 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-weld- ed stainless steel measuring cell for media compatibility.
There are no internal soft sealing materials that may react with the media or deteriorate over time.
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.
The transmitters are engineered to meet Class I, Division 1 explosion-proof protection for installation in hazardous environments.
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.
