Vertrieb durch DKS GmbH 01900 Großröhrsdorf Radeberger Str. 21 Model AMT-Ex Intrinsically Safe 4-20mA Dewpoint Transmitter Model AMT-Ex Dew-point Transmitter is a 3-wire 4-20mA transmitter, used for continuous measurement of humidity in dry process gases or dry compressed air. The Model AMT-Ex transmitter can also be factory configured to output a linear 4-20mA signal for any other moisture unit e.g. ppm(v), ppm(w), g/m3 and lb/MMSCF etc. Fast Response - Stable - Reliable - Accurate - Easy to Install. The long lasting sensing element offers excellent sensitivity, repeatability and speed of response. Each unit is supplied with a Certificate of Calibration, traceable to International Humidity Standards. FEATURES • 3 Wire Intrinsically Safe Dewpoint Transmitter • II 1GD Ex ia IIC T4 Ex iaD 20 T1350C (-20°C ≤ Ta ≤ +60°C) • Overall Range: -120°C to +20°C Dewpoint • Accuracy ± 2°C Dewpoint • INTEGRATED AUTOMATIC CALIBRATION Model AMT-Ex is ATEX certified and provides an Intrinsically Safe Dew Point Transmitter for hazardous area use when installed with the appropriate isolator. See Illustration oposite and additional information on pages 2 and 4. Measuring instrument conforms with EN 61326 • Can be configured for Linear 4-20mA signal in: °C & °F Dewpoint, ppm(v), g/m3, lb/MMSCF • Fault Diagnostics • Long Term Stability • Fast Response time • IP66 / NEMA4X Protection Hazardous and Zoned Areas This online dew point transmitter also incorporates an Automatic Calibration (AUTOCAL) feature that allows the user to carry out a field calibration / span check. The AUTOCAL feature is operated by two small button switches built within the transmitter enclosure. Safe Control Area Hygrometer Display See wiring options on pages 3 & 4 Up to 1km The integral RISC microprocessor circuitry of the Model AMT-Ex transmitter allows high resolution with advanced self diagnostics for fault conditions. It also enables periodic re-calibration of the moisture sensor, storing calibration data within the fully self contained unit. The mechanics of the Model AMT-Ex transmitter have been designed to cope with extreme environmental conditions. The rugged stainless steel construction offers protection to IP66 (NEMA4X), with the transmitter electrical connections made via a secure industrial connector. Model AMT-Ex transmitter can withstand 35,000 kPa (350bar) maximum pressure and by employing a low resistance cable, the transmitter can be located at significant distances in excess of 1000 metres from the control room. The Model AMT-Ex transmitter is supplied with a Certificate of Calibration, an instruction manual and 2m connecting cable. Dew-point Sampling Systems available - see www.amsystems.co.uk for mo
