Easidew EA2 Dew-Point Transmitter

Loop-powered ceramic dew-point transmitter for safe and hazardous areas.

ModelEasidew EA2
SKUMI-EASIDEW-EA2
CategoryDew Point & Moisture

Key Features

  • Range −110°Cdp to +20°Cdp (−100°Cdp to +20°Cdp on I.S. variant)
  • 2-wire loop-powered, 4-20 mA current source
  • Accuracy ±2°Cdp
  • Traceable 13-point calibration certificate
  • 316 stainless-steel sensor and sample block, 525 bar pressure rating
  • ATEX / UKCA / IECEx / cQPSus approved (I.S. variant)
  • 5/8" UNF, 3/4" UNF, G1/2" BSP or KF40 glove-box process connections
  • MiniDIN 43650 or M12 5-pin electrical connectors

Overview

The Easidew EA2 is a 2-wire loop-powered dew-point and moisture transmitter using Michell’s ceramic metal-oxide sensor technology. One stocked unit covers Class 1 to Class 6 compressed-air dryers and a wide range of industrial gas-quality duties, with an intrinsically safe (I.S.) variant available for hazardous-area installation.

Working Principle

A ceramic metal-oxide sensor element changes capacitance in proportion to adsorbed water vapour. Onboard microcontroller electronics linearise and temperature-compensate the signal, outputting a 4-20 mA current loop scaled to dew point or ppmV moisture content (M12 variant additionally supports Modbus RTU over RS-485).

Benefits

  • Single stocked product covers all compressed-air dryer classes
  • Sensor / recalibration exchange program minimises process downtime
  • Hazardous-area (I.S.) variant available without changing sensor technology
  • Optional enriched-oxygen cleaning for O2 purity applications
