The ever-increasing need for more and better data has led to rapid growth in wireless monitoring. Big data is king today. And since modern control systems and decision-making are driven by data, it’s not surprising that the oil and gas industry is investing heavily in wireless monitoring systems for remote installations. Wireless monitoring in remote areas comes with its own challenges, however. Most notably is the limited power supply. Conserving power is essential to ensure the pressure reading gets to the controller or monitor and that’s where low-power pressure transmitters can help.
Low-Power Pressure Transmitters for Wireless Monitoring
The new WIKA E-10 Eco explosion-proof pressure transmitter is sealed to withstand long-term exposure to the elements, and is available in a low-power 1–5 V configuration (6–30 VDC) that is ideal for wireless monitoring of drilling platforms, wellheads, pipelines, tanks, hydraulic systems, and gas compressors. The E-10 Eco can run on battery or a solar cell power supply. Even with near-continuous monitoring, given a startup/settling time of ≤2ms, the transmitter can be expected to run for several years on a single battery.
Safety Comes First With the Explosion-Proof Transmitter
Safety is the utmost priority in the oil and gas industry, and the WIKA E-10 Eco pressure transmitter is approved as explosion-proof for Class I, II, III Div. 1 hazardous areas based on FM and CSA standards. This transmitter is completely sealed, so it can be used in areas where flammable gases might be generated.
Pressure Transmitter Designed to Withstand Stress
The E-10 Eco transmitter reliably provides pressure readings at an accuracy of 0.5% of span, and can take just about anything. For example, this device features an extremely high resistance to vibration, pressure spikes, and moisture ingress (meets IP 67—NEMA 4x—ingress protection standards). It can also handle the harshest field conditions, making E-10 Eco an ideal transmitter for many applications in the O&G industry and related upstream sectors.
Specs and Features of the WIKA E-10 Eco
While extreme accuracy in instrument readings is required for some applications in the oil and gas industry, a reasonably accurate pressure gauge or transmitter is adequate for most. That’s where the WIKA E-10 Eco is ideal. This device was specifically developed for tasks such as wireless monitoring, where reliability and low-power draw are more critical than near-absolute accuracy. Note that this kind of application-specific design means the E-10 Eco costs notably less than other general-purpose explosion-proof transmitters. You can order the E-10 Eco with output analog signals from 4 to 20 mA, or in a low-power version with DC 1–5 V. Users can count on accuracy 0.5% of span under the standard temperature, atmospheric pressure, and humidity reference conditions (including non-linearity, hysteresis, zero offset, and end value deviation—measured error per IEC 61298-2). The E-10 Eco also offers a non-linearity (per IEC 61298-2) of ≤0.2% of span (BFSL) and a non-repeatability of ≤0.1% of span. The temperature error in the range 0 … 80°C (32 … 176°F) is: Mean temperature coefficient of zero point: ≤0.2% of span/10 K; mean temperature coefficient of span: ≤0.2% of span/10 K. The WIKA E-10 Eco can run on battery or a solar cell power supply. Even with near-continuous monitoring, given a startup/settling time of ≤2ms, the transmitter can be expected to run for several years on a single battery. Whether it’s on a drilling platform in the Gulf of Mexico or on a pipeline along the Alaska North Slope, you can count on the tough, explosion-proof WIKA E-10 or E-10 Eco to get you the pressure data you need – 24 hours a day, seven days a week. Our knowledgeable technical staff are happy to answer any questions you have about the latest addition to WIKA’s industry-leading line of pressure transmitters.
