Easidew PRO I.S. Intrinsically Safe Dew-Point Transmitter

The Easidew PRO I.S. is a reliable, accurate 2-wire dew-point transmitter widely used for humidity measurement in gases and liquids. Built with Michell's advanced ceramic sensor technology, it delivers long-term stability and fast response for the most demanding industrial applications.

Key Features

• Wide Measurement Range: -110 to +20 °Cdp for both gas and liquid applications
• High Accuracy: ±1 °Cdp (+20 to -60 °C), ±2 °Cdp (-60 to -110 °C)
• Global Hazardous Area Certifications: ATEX, IECEx, CCSAUS (US & Canada), FM, TC TR Ex
• High Pressure Rating: Up to 45 MPa (450 barg)
• Robust Construction: 316 stainless steel housing with IP66 / NEMA 4 protection
• Fast Response: T63 < 5 seconds from dry to wet
• Traceable Calibration: 13-point calibration certificate traceable to NPL and NIST
• 2-Wire 4-20 mA Output: Easy integration into existing control systems

Applications

• Natural gas production and processing
• Pipeline drying and gas metering
• LNG production and receiving terminals
• Petrochemical process liquids
• Catalyst protection
• CNG drying
• Metallurgical furnace protective gas
• Hazardous area compressed air

Gas & Liquid Humidity Measurement

For gas applications, the Easidew PRO I.S. outputs dew point or ppmV (0-3000 ppmV standard). For liquid applications, the Easidew PRO LQ I.S. variant outputs ppmW (0-1000 ppmW) with pre-programmed saturation constants for common liquids including butane, methane, propane, ethylene, and more.

Flexible Installation

Compatible with standard process connections: 5/8" UNF, G1/2", and 3/4" UNF. Optional 316 stainless steel sampling block and sensor mounting bracket available. Electrical connection via M20 x 1.5 mm cable gland.
