Single Channel Dew Point Hygrometer Ranges available between -120°C to +20°C (-166°F to +68°F) dewpoint User friendly solution for continuous on-line dewpoint measurement in dry process gases and dry compressed air, offering powerful functionality and simple interface through advanced digital technology. Fast Response - Stable - Reliable - Accurate - Easy to Install. 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 ⅛ 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. FEATURES • User Friendly & Advanced Functionality • Factory set in either °C or °F Dewpoint, ppm(v), ppb(v), g/m3 or lbs/MMSCF • 22V – 253V AC or DC Operation • Linear 4-20mA Retransmission Signal • 2 Independent, Fully Programmable Alarm Relays “AUTOCAL” CALIBRATION FEATURE Fast Response Long Term Stability IP66 / NEMA4 Weatherproof Protection Calibration traceable to National & International Standards Combination of advanced digital technology of the display electronics and the transmitter, 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. Model DS1200-AMT Dewpoint Hygrometer is fully configured to the customer's specifications. The instrument offers two fully programmable alarm relays, which can be independently set across the full operating range. 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 dewpoint transmitters, 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 transmitter allow calibration data to be stored within its memory, making transmitters completely field interchangeable. Each transmitter 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 unit to be sited in excess of 1000m from the transmitter, connected by a simp

Alpha Moisture Systems Model DS1200-AMT Application Wiring Diagrams Model DS1200 Display Connection Details Corrosive Gases: The Sensor should not be exposed to corrosive gases (or corrosive contaminants in the gas sample) as these can chemically attack the sensor, impairing calibration accuracy and/or damaging it beyond economic repair. Examples of such gases are mercury (Hg), ammonia (NH3), chlorine (Cl2) etc. Strong oxidising agents such as ozone (O3) should also be prevented from coming into contact with the sensor.
