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 user to carry
out a field calibration, span check. The AUTOCAL feature is
operated by means of two small button switches on the side of the
transmitter enclosure (see picture). 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.
