Shaw Moisture Meters intrinsically safe dewpoint transmitter, the Model SDT-Ex, is designed to meet the stringent demands of industrial applications.
Compact, 3 wire, 4 – 20 mA , the Model SDT-Ex is certified intrinsically safe to ATEX: Ex II 1 GD Ex ia IIC T4 Ga (-20 °C ≤ Ta ≤ +60 °C) and IECEx: Ex ia IIIC T200135 °C Da (-20 °C ≤ Ta ≤ +60 °C) for use in hazardous areas using a signal isolator.
Incorporating advanced electronics, this intrinsically safe dewpoint transmitter derives its power from 7 – 28 V DC non-isolated power source and is configured to output a linear, isolated, 4 – 20 mA signal for distances up to 1,000 metres (3,280 ft).
Utilising the ultra high capacitance SHAW sensor technology, various dewpoint ranges are available covering an overall range from -100 °C to +20 °C (-148 °F to +68 °F) dewpoint. The 4 – 20 mA output is configurable in °C dewpoint, °F dewpoint, ppm(v), g/m³ and lb/MMSCF.
Fully self contained within a robust housing and providing weatherproof protection to IP66/NEMA 4X. The Model SDT-Ex intrinsically safe dewpoint transmitter is supplied ready to use with a Calibration Certificate traceable to National & International Humidity Standards, instruction manual and two metres (6.56 ft) of cable.
