DS4000-Exd-AMT-Ex Dewpoint Hygrometers For Ex Hazardous Areas. Features and Benefits GUBH Flameproof Enclosure Ex II 2 G D Designed for installa on in to Ex Hazardous areas. Flameproof to ATEX and IECEx cer fica on for use in poten ally explosive atmospheres Offered with either DS4000 Advanced Display or DS1200 Standard Display Indicators and AMT-Ex Intrinsically Safe Dewpoint Transmi er Transmitter and Enclosure. IP66 Rating. Incorporates Signal Isola on within the enclosure Heat-resistant toughened glass observa on window Range of enclosures available DS4000-Exd-AMT-Ex is a single channel, online hygrometer with built-in isolator designed to accurately measure trace moisture in process gases u lising a range of dedicated, ultra high capacitance, field mountable AMT-Ex Dewpoint Transmi er. The DS4000-Exd-AMT-Ex Dewpoint Hygrometer is located in the Hazardous Zone. The GUBH Flameproof Enclosure Ex II 2 G D is flameproof to ATEX and IECEx Cer fica on for use in poten ally explosive atmospheres. The system incorporates an “Automa c Calibra on (AutoCal)” func on and encompasses measurement needs from -120 °C to +20 °C (-184 °F to +68 °F) dewpoint. The AMT-Ex Transmi er is highly sensi ve and has been designed and condi oned for long term stability and accuracy. Addi onally, the transmi er is ATEX cer fied for intrinsic safety so can be used in hazardous environments with the isolator housed within the DS4000-Exd Unit. There are three Hot Key front panel key func ons to gain rapid access to set alarms trip points and choice of displayed engineering units. These func ons can be locked to prevent unauthorised tampering. Users may choose to view the trace moisture levels in °C or °F dewpoint, ppm(v), ppm(w), g/m³ or lb/MMSCF on the 5 digit, seven segment red LED display. DS4000-Exd-AMT-Ex contains two independent, fully user programmable alarm contacts to provide all the versa lity required for any applica on. A digital communica on channel is provided via a RS485 serial connec on for remote interroga on of measured values and status of alarms and instrument.
