General

The duct humidity transmitter uses a highly accurate and reliable Thermoset Polymer based capacitance humidity sensor and state-of-the-art digital linearization and temperature compensated circuitry to monitor humidity levels. The sensor is encapsulated in a 228.60 mm (9”) long by 12.7 mm (0.5”) diameter 304 S/S probe. An 60 micron HDPE filter protects the sensor for contaminants. A compact ABS enclosure with a hinged and gasketed cover is provided for ease of installation. An optional integrated temperature sensor is also are available.

Features
