Dewpoint Transmitter

By July 19, 2017Uncategorised

The SHAW Model SDT and Model SDT-Ex dewpoint transmitters are designed to meet the stringent demands of industrial applications and extreme environmental conditions.

Both the Model SDT and SDT-Ex dewpoint transmitters utilise the industry standard, ultra high capacitance SHAW moisture sensing technology. Various dewpoint ranges are available covering an overall range from -100 °C to +20 °C dewpoint (-148 °F to +68 °F). The dewpoint transmitters’ 4 – 20 mA output is configurable in °C dewpoint, °F dewpoint, ppm(v), g/m³ and lbs/MMscf.

Incorporating advanced electronics, power can be derived from 7 -28 V DC non isolated power source and configured to output a linear, isolated, 4 -20 mA signal for distances up to 1,000 metres. The mechanics of the Model SDT and SDT-Ex dewpoint transmitter have been designed to cope with extreme environmental conditions.

The Model SDT-Ex dewpoint transmitter is certified intrinsically safe to ATEX standards for use in hazardous areas using a signal isolator.

Designed with the operator in mind, for reliable and accurate measurements, the SHAW dewpoint transmitters are extremely easy to install and operate, requiring little or no maintenance.
