MOISTURE METERS AcuDewHigh Performance Dewpoint Transmitter The Shaw Moisture Meters AcuDew Dewpoint Transmitter is a compact, 2 wire, 4-20 mA loop powered transmitter, used for trace moisture measurement of process gases and dry compressed air. Utilising the ultra high capacitance SHAW dewpoint sensor, the AcuDew is a robust and reliable dewpoint transmitter, offering excellent sensitivity, repeatability and speed of response. The AcuDew dewpoint transmitter also incorporates the SHAW AutoCal feature to ensure accuracy between laboratory calibrations. AcuDew provides a linear 4-20 mA signal over the chosen measurement range, loop powered by a 7-28 V DC source. Various dewpoint ranges are available, covering an overall range from -120 °C to +20 °C dewpoint (-184 °F to +68 °F). The output is configurable in °C dewpoint, °F dewpoint, ppm(V), ppb(v), g/m3 and lb/MMSCF. The AcuDew dewpoint transmitter is also available with Modbus RTU Serial Line RS485 digital communication. The rugged stainless-steel construction and industrial M12 connector provide a protection rating of IP66 (NEMA 4X) and can withstand extreme environmental conditions across a wide range of industrial applications. The AcuDew dewpoint transmitter has been tested to withstand pressures up to 35,000kPA (350 bar) for direct connection in to pipelines. Easy to install and operate, requiring little or no maintenance, AcuDew offers reliable and accurate measurements. The microprocessor circuitry of the AcuDew dewpoint transmitter drives its high resolution to provide advanced selfdiagnostics for fault conditions. When installed in remote locations, the 4-20 mA signal can be transmitted to a control system over distances up to 1,000 meters (3,280 feet). The AcuDew is fully compatible with the Acu range of single channel displays: the AcuLoop plug-in signal indicator for local display; the panel mount AcuVu with 4-20 mA retransmission and fully programmable alarms; and the AcuTrak with additional on-board pressure dewpoint calculations and RS485 communications. Each AcuDew transmitter is supplied ready for use with a Certificate of Calibration traceable to National and International Humidity Standards, an instruction manual and 2 m of cable. • 2-wire, loop powered, 4-20 mA dewpoint transmitter • AcuDew available with Modbus RTU Serial Line RS485 digital commumication • Various ranges: overall range -120 °C to +20 °C dewpoint (-184 °F to +68 °F) • AutoCal (automatic calibration) feature • Output configurable in °C dewpoint, °F dewpoint, ppm(V), ppb(v), g/m3 and lb/MMSCF • Open/short circuit detection • Weatherproof rating IP66 (NEMA 4X) • Fully compatible with the single channel displays: AcuLoop, AcuVu, AcuTrak, SU4 sample system and SWS sample sys
