The AcuDew two-wire, loop-powered moisture transmitter has a linear 4- to 20-mA output corresponding to the measured moisture content. Its high-capacitance aluminum oxide sensing element provides excellent sensitivity, especially at low moisture content, as well as high speed of response and repeatability. The transmitter can be factory-configured to provide an output corresponding to various moisture parameters, including dew/frost point temperature, parts per million by volume or parts per billion by volume. Locally and remotely mounted display and power supply devices are available. The field span verification (FSV) feature allows users to ensure the transmitter’ accuracy between annual factory recalibrations.
