AcuDew, the new addition to the SHAW dewpoint transmitters range.
This is a 2-wire, loop powered transmitter with a linear 4-20 mA signal, which can be transmitted to a control system over distances of up to 1,000 metres (3,280 feet). Various dewpoint ranges are available covering an overall range of -120 °C to +20 °C (-148 °F to +68 °F) dewpoint and the output units are configurable in °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m³ and lb/MMSCF. The AcuDew is built of a robust stainless-steel construction with an industrial M12 connector and provides a protection rating of IP66 (NEMA 4X). This new dewpoint transmitter includes the SHAW AutoCal feature as standard, allowing users to check the span of the instrument and correct for any deviation between annual laboratory calibrations.
AcuDew is fully compatible with the new range of single channel displays: 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 onboard pressure dewpoint calculations and RS485 communications, as well as the existing SU4 sample system.
Easy to install, easy to operate, the reliable and accurate AcuDew dewpoint transmitter requires little or no maintenance.
Various dewpoint ranges are available covering an overall range from -100 °C to +20 °C dewpoint (-148 °F to +68 °F). The 4 – 20 mA output is configurable in °C dewpoint, °F dewpoint, ppm(v), g/m³ and lb/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 SHAW dewpoint transmitters, have been designed to cope with extreme environmental conditions.
Designed, with the operator in mind, for reliable and accurate measurements, the SHAW Model AcuDew and SDT-Ex are extremely easy to install and operate, requiring little or no maintenance.
