AMT露点变送器

Model AMT Dewpoint Transmitter is a two wire 4-20mA loop powered unit, used for continuous measurement of moisture levels in gases and compressed air, which will output a linear 4-20mA signal corresponding to the dewpoint temperature. The Model AMT dew-point transmitter can also be factory configured to output a 4-20mA linear signal for any other moisture unit for example, ppm(v), ppm(w), g/m3 or lb/MMSCF.

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 to ±2oC dewpoint.

The built in Automatic Calibration (AUTOCAL) feature comes as standard on all the Model AMT range, this allows the us英国阿尔法DS1200露点分析仪

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 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.

To avoid tamper, the switches are locked in normal use and can only be activated by following a certain routine.

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 as standard.
