HS-D Transmitter Series

The HS-D Transmitter Series are duct humidity and temperature transmitters. They use a highly accurate and reliable Thermoset Polymer based capacitance humidity sensor and Platinum RTD temperature sensor along with 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 S/S probe. A 60 micron HDPE filter protects the sensor from contaminants. Excellent long term stability and quick response time combined with temperature compensation make the HS-D Series the ideal choice for the HVAC market. A variety of enclosure types are available. All models are available with RH accuracies of 2%, 3% or 5%.
