Fits industrial dew-point measurement where you need a Michell Easidew EA2 2-wire transmitter with ceramic metal-oxide sensor and −110 to +20 °Cdp class range.
Key advantages
- Range — −110 to +20 °C dew point (−166 to +68 °Fdp); ppmV moisture scaling class
- Accuracy — ±2 °Cdp (±3.6 °Fdp)
- Output — 2-wire 4–20 mA loop-powered; dew point or ppmV
- Sensor — Michell ceramic metal-oxide moisture sensor; 316 SS wetted parts
- Pressure — High-performance barrier to 525 bar class
Typical applications
- Compressed air and dryer dew-point monitoring.
- Glove-box and process gas moisture with KF40 or threaded connections.
- Loop-powered moisture points into PLC/DCS.
Selection guide
- Connection — 5/8" UNF, 3/4" UNF, G1/2", or KF40
- Electrical — MiniDIN 43650 vs M12
- Scaling — Dew point vs ppmV on 4–20 mA
- I.S. — Easidew I.S. options (ATEX/IECEx/cQPSus/UKCA) if required
Common mistakes
- Mounting in wet liquid service — Easidew is for gases/moisture in gas.
- Ignoring sample pressure when converting to ppmV.
- Skipping I.S. version in classified areas.
When to RFQ / what to tell us
- Dew-point span, gas, and pressure.
- Process/electrical connection; I.S. yes/no.
- Quantity and ship-to.
