Michell Instruments Easidew EA2 Dew Point Transmitter

Overview

The Michell Instruments Easidew EA2 dew point transmitter is a compact, loop-powered instrument for measuring trace moisture content in compressed air and industrial gas systems, covering a wide dew point range from −110°C up to +20°C. Built around Michell’s proven ceramic moisture sensor technology, the Easidew EA2 delivers stable, drift-resistant dew point measurement with a simple 2-wire 4…20 mA output, making it straightforward to integrate into existing process control and building management systems.

For compressed air systems, natural gas processing, and industrial drying applications across Oman and the wider GCC, the Easidew EA2 provides reliable moisture monitoring that protects downstream equipment and processes from the damaging effects of condensation, corrosion, and hydrate formation. Seven Star LLC supplies the Michell Instruments Easidew EA2 dew point transmitter to customers across Muscat, Sohar, Salalah, and the Sultanate of Oman as an authorized Michell Instruments distribution partner, providing genuine factory-sourced instruments with full documentation and technical support.

Measurement and Operating Principle

The Easidew EA2 uses a ceramic capacitive moisture sensor to measure the dew point temperature of the sample gas directly, avoiding the drift and contamination issues associated with chilled-mirror and other mechanical dew point measurement methods. The sensor responds to changes in ambient moisture within approximately 5 minutes to T95 when moving from dry to wet conditions, giving process operators timely visibility into moisture excursions before they cause downstream equipment damage or product quality issues.

The transmitter provides a 2-wire, loop-powered 4…20 mA output that can be user-configured to represent either dew point directly (scaled from −110°C up to +20°C) or moisture content in ppmV (scaled from 0 to 3000 ppmV), giving flexibility to match the output to the host system’s preferred engineering units. Accuracy is specified at ±2°C dew point with repeatability of 0.5°C dew point, and each unit ships with a traceable 13-point calibration certificate documenting performance across the measurement range.

Engineering Design of the Michell Easidew EA2

The Easidew EA2 features a 316 stainless steel sensor housing and sample block, cleaned for oxygen service, making it suitable for use in oxygen-enriched gas streams where material compatibility and cleanliness are critical safety considerations. Process connection options include G1/2 inch BSP, 3/4 inch UNF, and 5/8 inch UNF threads as standard, with additional adapter options available to interface with a wide range of existing sample system fittings. The transmitter is rated to NEMA 4 / IP66 and operates across an ambient temperature range of −40°C to +60°C, supporting installation in both indoor process areas and outdoor sample cabinets.

Factory-programmed diagnostics continuously monitor for sensor fault conditions, under-range dew point, and over-range dew point, alerting operators to abnormal readings that may indicate sensor contamination or measurement outside the calibrated range. Michell’s sensor exchange program allows operators to replace the sensing element ahead of the recalibration due date, minimizing instrument downtime and keeping the overall cost of ownership low compared to instruments requiring full unit replacement or extended off-site recalibration.

Industrial Applications

The Easidew EA2 is widely used for moisture monitoring in compressed air systems, natural gas processing and transmission, instrument air quality verification, and industrial drying and dehydration processes. Its wide measurement range and oxygen-service-cleaned construction make it equally suitable for cryogenic gas applications and oxygen-enriched process streams where standard dew point instruments are unsuitable.

Across Oman’s oil, gas, and industrial sectors, including facilities supporting the Sohar and Salalah economic zones, the Easidew EA2 gives plant operators a reliable, cost-effective solution for protecting compressed air and process gas systems from moisture-related damage and product quality issues. As an authorized Michell Instruments partner, Seven Star LLC supports these projects throughout the Sultanate of Oman with genuine factory-sourced transmitters, sensor exchange services, and after-sales support.
