DS1500-Exd Dewpoint Hygrometer For Ex Hazardous Area Zones. Features and Benefits GUBH Flameproof Enclosure Ex II 2 G D Designed for installa on in Ex Hazardous area Zones. Flameproof to ATEX and IECEx cer fica on for use in poten ally explosive atmospheres Offered with the DS1500 Advanced Display. Used with the AMT-Ex Intrinsically Safe Dewpoint Transmi er (Ordered Seperately) Incorporates Signal Isola on within the Exd enclosure Enclosure: IP66 Rating. Heat-resistant toughened glass observa on window DS1500-Exd is a single channel, online hygrometer with built-in isolator designed to accurately measure trace moisture (dewpoint) in process gases u lising a range of dedicated, ultra high capacitance, field mountable AMT-Ex Dewpoint Transmi ers. The DS1500-Exd 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. DS1500-Exd is connected to the Alpha Moisture Systems’ AMT-Ex Dewpoint Tranmi er. The AMT-Ex 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. DS1500-Exd contains four independent, fully user programmable alarm contacts accessed by means of five Hot Keys on the front panel of the display to provide all the versa lity required for any applica on. A digital communica on channel is provided via a RS485 (MODBUS RTU Communica on Protocol) serial connec on for remote interroga on of measured values and status of alarms and instrument.
