Description
The Shaw Moisture Meters SDT-Ex Intrinsically Safe Dew Point Transmitter is designed to meet the stringent demands of industrial applications. Suitable for the continuous measurement of trace moisture in dry compressed air and industrial process gases and is ideal for hydrocarbon, petrochemical and hydrogen applications.
Compact, 3 wire, 4-20 mA, loop powered dewpoint transmitter. 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 when using a signal isolator.
The SDT-Ex is configurable to output a linear, isolated, 4-20 mA signal. This intrinsically safe dewpoint transmitter will not suffer any loss of signal when sited up to 3,280 ft away from the display.
Various dewpoint ranges are available, covering an overall range from -148°F to +68°F (-100°C to +20°C) dewpoint. The 4-20 mA output is configurable to display in °C dewpoint, °F dewpoint, ppm(V), g/m³ and lb/MMSCF.
