The Shaw Moisture Meters AcuDew Dewpoint Transmitter delivers robust and reliable operation as a 2-wire, 4-20 mA loop-powered device. Using ultra high capacitance moisture sensing technology, the AcuDew ensures high sensitivity, accuracy, repeatability, and speed of response.

The AcuDew features the Shaw AutoCal function, allowing users to check and adjust the instrument’s span to correct for any deviation between annual laboratory calibrations. AutoCal can be performed on dewpoint instruments in situ, without needing skilled personnel or specialised equipment.

AcuDew offers various dewpoint measurement ranges, covering -184°F to +68°F (-120°C to +20°C), with configurable output units in °C dewpoint, °F dewpoint, ppm(V), ppb(V), g/m³ and lb/MMSCF. The stainless-steel design includes an industrial M12 connector, which reduces setup time and simplifies installation and maintenance for wiring systems. AcuDew is is engineered to perform in extreme environmental and industrial conditions, providing an IP66 (NEMA 4X) protection rating.

The AcuDew can be directly installed in the process line or integrated into a sample conditioning system. As a result, the operation is simple, with minimal maintenance required. Shaw tests each dewpoint transmitter to withstand pressures up to 35,000kPa and enables direct pipeline connection. The device requires no user operated controls during use, ensuring long term unattended operation.
