The Edgetech Instruments AcuDew Moisture Transmitter is a two wire, loop powered moisture transmitter with linear 4 to 20 mA output corresponding to the measured moisture content. Its high capacitance aluminum oxide sensing element provides outstanding sensitivity, especially at low moisture content, as well as high speed of response and repeatability. The advanced electronic design of the AcuDew uses modern, high speed, high resolution hardware and software techniques for superior performance. The AcuDew 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 optionally available. The Field Span Verification (FSV) feature of the AcuDew allows the user to ensure accuracy of the transmitter between annual factory recalibrations.
