Vertrieb durch DKS GmbH 01900 Großröhrsdorf Radeberger Str. 21 Model AMT Dewpoint Transmitter 4-20mA. Ranges available between -1200C to +200C (-1840F to +680F) dewpoint Model AMT Dewpoint Transmitter is a two wire 4-20mA loop powered transmitter, used for continuous measurement of moisture in dry process gases or dry compressed air, which will output a linear 4-20mA signal corresponding to the dewpoint temperature. The Model AMT transmitter can also be factory configured to output a 4-20mA linear signal for any other moisture unit e.g. ppm(v), ppm(w), g/m3, lb/MMSCF etc. ACTUAL Fast Response - Stable - Reliable - Accurate SIZE* Easy to Install. The Ultra High Capacitance sensing element is long lasting and offers excellent sensitivity, repeatability and response speed. Each unit is supplied with a Certificate of Calibration, traceable to International Humidity Standards, validating accuracy better than ±20C dewpoint. FEATURES • 2 Wire Loop Powered Dewpoint Transmitter • Overall Range: -1200C to +200C Dewpoint • Accuracy better than ± 20C Dewpoint • INTEGRATED AUTOMATIC CALIBRATION • Can be configured for linear 4-20mA signal in: 0C & 0F Dewpoint, ppm(v), ppb(v), g/m3, lb/MMSCF Measuring instrument conforms with EN 61326 * when printed at 100% on A4 format Temperature Compensation Failure Diagnostics Long Term Stability Fast Response Time IP66 / NEMA4X Protection The transmitter also incorporates an Automatic Calibration (AUTOCAL) feature, which 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. To avoid tamper, the switches are locked in normal use and can only be activated by following a specific routine from the manual. The integral RISC microprocessor circuitry of the Model AMT 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. Loop powered by a 7V to 28V dc source, the Model AMT transmitter will provide a linear 4-20mA signal over the chosen range. The mechanics of the Model AMT 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 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. Designed with the operator in mind for reliable and accurate measurements, the Model AMT transmitter is extremely easy to install and operate, requiring little or no maintenance. The Model AMT transmitter is supplied with a Certificate of Calibration, an instruction manual and 2m connecting cable. Note: The Model AMT is not suitable for Ammonia (NH3), Chlorine (CI) and Hydrogen Chloride (HCI). SF6 can be monitored with no effect to the sensor element. Sulphur Dioxide (SO2) can be monitored if the moisture content is low, less than 100ppm(
