​​The Shaw Moisture Meters Model AcuDew Dewpoint Transmitteris a compact, 2 wire, 4-20 mA loop powered transmitter, used for tracemoisture measurement of process gases and dry compressed air.Utilising the Ultra High Capacitance SHAW DewpointSensor, the AcuDew is a robust and reliabledewpoint transmitter, offering excellentsensitivity, repeatability and speed of response.The AcuDew transmitter also incorporatesthe SHAW AutoCal feature to ensure accuracybetween laboratory calibrations.The AcuDew dewpoint transmitter provides a linear 4-20 mA signal over the chosen measurement range, loop poweredby a 7-28 V DC source. Various dewpoint ranges are available covering an overall range from -120 °C to +20 °C dewpoint(-148 °F to +68 °F). The output is configurable in °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m3 and lb/MMSCF.The rugged stainless-steel construction and industrial M12 connector provide IP66 (NEMA 4X)protection and can withstand extreme environmental conditions across a wide range of industrialapplications. The AcuDew dewpoint transmitter has been tested to withstand pressures up to35,000kPA (350 bar) for direct connection in to pipelines.Easy to install and operate, requiring little or no maintenance, the AcuDew offers reliable andaccurate measurements. The microprocessor circuitry of the AcuDew dewpoint transmitter drives itshigh resolution to provide advanced self-diagnostics for fault conditions. When installed in remotelocations, the 4-20 mA signal can be transmitted to a control system over distances up to 1000meters (3280 feet).The AcuDew is fully compatible with the Acu range of single channel displays: the AcuLoop pluginsignal indicator for local display; the panel mount AcuVu with 4-20 mA retransmission and fullyprogrammable alarms; and the AcuTrak with additional on-board pressure dewpoint calculationsand RS485 communications.The Model Acudew is supplied ready to use, with a Certificate of Calibration traceable to Nationaland International Humidity Standards, instruction manual and two metres of cable.
