Model DS1200 from Alpha Moisture Systems is a single channel on-line hygrometer designed to measure dewpoint in process gases and dry compressed air. The panel mounted ? DIN dewpoint meter, providing panel protection to IP65 (NEMA4X), combines with the Model AMT range of ultra high capacitance sensors for accurate trace moisture measurement. Combination of advanced digital technology of the display electronics and the sensor, makes this the system of choice for a wide range of applications where precise indication, control and monitoring is critical. Model DS1200-AMT system can be factory configured to read in °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m³ or lbs/MMSCF. The measured value is displayed on a large 4 digit, 13.8mm high, fourteen segment LED display. The instrument offers two fully programmable alarm relays, which can be independently set across the full operating range of the sensor. An optically isolated analogue signal, linear with the measured unit, is also available to interface with any external device. Model DS1200-AMT can be supplied with any one of a range of sensors, which have all been specially manufactured to provide long term stability, so ensuring a long and trouble free service life. The long lasting sensing element offers excellent sensitivity, repeatability and response speed – especially on dry down. Integrated electronics in each sensor allows calibration data to be stored within its memory, making sensors completely field interchangeable. Each sensor is calibrated to provide overall system accuracy of better than ±2°C dewpoint and supplied with a certificate traceable to international humidity standards. Model DS1200-AMT also incorporates the invaluable “AUTOCAL” feature for easy field verification of the system response, without recourse to any additional equipment. Accidental or unauthorised operation is prevented by a simple initiation routine. The system allows the display console to be sited in excess of 1000m from the sensor, connected by a simple twisted pair cable. Model DS1200-AMT Dewpoint Hygrometer is fully configured according to the customer’s specifications and is supplied complete with 2 metres of connecting cable and user manual. For ease of installation, an optional flow through sample cell can be ordered together with suitable pipe connections.
