The improved Easidew two-wire transmitter is a low-cost, rugged dewpoint transmitter for continuous measurement in compressed air or process gas. The transmitter now has the ability to be connected in a two-wire, loop-powered configuration, while maintaining complete backward compatibility with all existing three-wire installations. It also offers an output that is configurable in ppmv moisture content (0–100, 0–1,000 and 0–3000 ppmv ranges). Other enhancements include a new 10-mm HDPE sensor guard designed to show contamination for service ease, and improved software and firmware to protect calibration from the most severe levels of EMI. The Easidew transmitter has a dewpoint measurement range from –148°F to 68°F and an accuracy of ±3.6°F. The instrument also features a field adjustable 4–20-mA linear analog output, resettable failure modes for over-range, under-range and sensor-fault conditions, and temperature compensation.
