Superdew 3 WP Dewpoint Hygrometer Datasheet-1

Superdew 3 WP Dewpoint Hygrometer The Superdew 3 WP from Shaw Moisture Meters is a robust, single-channel inline dewpoint hygrometer engineered to deliver accurate dewpoint measurements in process gases and compressed air. Housed in a wall mount, weatherproof enclosure with IP65 (NEMA 4X) rated panel protection. The Superdew 3 WP is built for reliable performance, even in demanding environments. At its core, the Superdew 3 WP combines the proven precision and repeatability of the SHAW dewpoint sensor with advanced digital electronics, making it the preferred choice for applications that demand accurate trace moisture measurement and monitoring. Every sensor is individually calibrated, ensuring an overall system accuracy better than ±2 °C (±3.6 °F) dewpoint. Each unit is supplied with a certificate of calibration traceable to National & International Humidity Standards at NPL, providing complete confidence in your measurements. The Superdew 3 WP is fully user configurable, allowing readings to be displayed in °C, °F, ppm(V) or lb/MMSCF on a bright, five-character LED display. It features two fully programmable alarm relays, each independently adjustable across the sensor’s full operating range. Set points can be conveniently viewed and adjusted using the intuitive front panel keypad. Standard features include an isolated 4–20 mA analogue output, with a span customisable to the sensor’s range. For added flexibility, the system allows the Superdew 3 WP instrument to be installed over 1,000 metres from the dewpoint sensor, enabling convenient placement in your facility. Supplied as a complete package, the Superdew 3 WP dewpoint hygrometer includes the dewpoint hygrometer, wall mount brackets, SHAW dewpoint sensor, sensor holder and two metres of sensor cable and configured to your exact requirements. Large clear digital display with back light Two alarms (view/adjust setpoints from front panel) Various ranges: overall range -100 °C to +20 °C (-148 °F to +68 °F) dewpoint Two years guarantee on dewpoint hygrometer and dewpoint sensor User friendly and advanced functionality Wall mount enclosure Universal input: 90 V to 250 V AC (24 V DC option available) AutoCal (automatic calibration) feature Weatherproof rating - IP65 (NEMA 4X) User selectable digital indication in °C, °F, ppm(V) or lb/MMSCF Linear isolated 4-20 mA retransmission signal, adjustable span Fully interchangeable SHAW dewpoint sensors and ranges Supplied with a Certificate of Calibration traceable to Nat
