Superdew 3 Hygrometer The Superdew 3 from Shaw Moisture Meters is a single channel inline hygrometer designed to measure dewpoint in process gases and compressed air. The panel mounted enclosure provides panel protection to IP54. The combination of the highly accurate, repeatable SHAW dewpoint sensor and advanced digital electronics, make this the instrument of choice for a wide range of applications where precise measurement, control and monitoring is critical. Each dewpoint sensor is calibrated to provide overall system accuracy of better than ±2 °C (±3.6 °F) dewpoint and supplied with a calibration certificate traceable to international standards. The Superdew 3 can be user configured to display in °C, °F, ppm(V) or lb/MMSCF on an easy to read five character LED display. The instrument offers two fully programmable alarm relays, which can be independently set across the full operating range of the sensor. Set points can be viewed and adjusted from the front panel keypad. An isolated 4 - 20 mA analogue output is supplied as standard. The span of this output can be configured across the range of the dewpoint sensor. The system allows for the Superdew 3 inline instrument to be sited in excess of 1,000 metres from the dewpoint sensor. The Superdew Dewpoint Hygrometer Package is fully configured according to the customer’s specifications and consists of the Superdew inline dewpoint analyser, SHAW dewpoint sensor, sensor holder and two metres of sensor cable. User selectable digital indication in °C, °F, ppm(V) or lb/MMSCF Linear isolated 4 - 20 mA retransmission signal, adjustable span Two alarms (view/adjust setpoints from front panel) Various ranges: overall range -100 °C to +20 °C (-148 °F to +68 °F) dewpoint Fully interchangeable SHAW dewpoint sensors and ranges Universal input: 90 V to 250 V AC (24 V DC option available) Two years guarantee on dewpoint meter and dewpoint sensor AutoCal (automatic calibration) feature User friendly and advanced functionality Large clear digital display with back light IP54 rated front panel Supplied with a Certificate of Calibration traceable to National
