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). 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.
