Dew Point
The dew point is defined as the lower temperature to which air must be cooled in order for condensation to occur. The dew point is dependent on the concentration of water vapor present, and therefore on the relative humidity.

Dewsmart Sensor 
The model DS1200 is an on-line hygrometer designed to measure moisture in process gases and dry compressed air. The panel mounted display and AMT sensor are both rated for NEMA 4 service. The DS1200 with AMT ultra-high capacitance sensors provide excellent performance and accurate trace moisture measurement. The combination of advanced digital technology of the display electronics and sensor, makes this the system of choice for a wide range of applications where precise indication, control and monitoring is critical.

The model DS1200-AMT system can be factory configured to read out in °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m³ or lbs/ MMSCF. The measured value is displayed on a large 4 digit, 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 4-20 ma signal, linear with the measurement units, is also provided.

The model DS1200-AMT can be supplied with one of three different sensor ranges.

The long lifetime sensor offers excellent low end sensitivity, repeatability and response speed - especially on dry down. Integrated electronics in each sensor allow calibration data to be stored within its memory, making sensors completely field interchangeable. Each sensor is calibrated to provide an accuracy of better than ±2°C dewpoint and is supplied with a certificate traceable to NIST or other standards.

The “ AUTOCAL” feature provideds for easy field verification of the system response, without the need for additional equipment.
The DS1200-AMT display can be remotely mounted over 1/2 mile (3280 feet) from the sensor, connected by
a simple twisted pair cable.
