Specially designed for HVAC, the HT-1300 duct mount humidity sensor is a cost effective, highly accurate and reliable solution for measuring relative air humidity and temperature. The enclosure minimizes installation cost and provides outstanding protection against contamination and condensation, thus ensuring flawless operation. The HT-130x-UD1 employs the new humidity/temperature sensor with excellent long-term stability and resistance to pollutants. Long term performance is granted by the PTFE membrane fitted to the standard protection cap, suitable for most common HVAC applications. The standard protection cap can be replaced with a series of alternative protection caps specially designed for harsh environments. Features Power supply 15...35 VDC / 24 VAC ±20% Humidity range 0...100% Humidity output 0...10 VDC Humidity accuracy 2,5% from 10 to 95% RH Temperature outputs 0...10 VDC or Pt 100, Pt1000 or NTC 2k2 Duct probes length 200 mm Protection class: IP65 Protection caps for harsh environment application Protection class: IP65 Inspection Certificate according EN 10204:2004
