Description
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 Certification for use in potentially explosive atmospheres.
The system incorporates an “Automatic Calibration (AutoCal)” function and encompasses measurement needs from -120 °C to +20 °C (-184 °F to +68 °F) dewpoint. The AMT-Ex Transmitter is highly sensitive and has been designed and conditioned for long term stability and accuracy.
Additionally, the transmitter is ATEX certified 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 functions to gain rapid access to set alarms trip points and choice of displayed engineering units. These functions 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 versatility required for any application. A digital communication channel is provided via a RS485 serial connection for remote interrogation of measured values and status of alarms and instrument.
