Standard Duct
Humidity Sensors
DESCRIPTION
HED Standard Series duct mount humidity transmitters offer high performance
in an easy to install housing at an affordable price. The thin-film capacitive sensor
element provides high accuracy and performance, great long-term stability, and
full recovery from saturation. Temperature sensing options are also available.
The duct-mounted HED includes a rugged all plastic housing with a tool-less
gasketed entry lid, large cage clamp terminal blocks, and sturdy ABS material. All
Standard models come with a standard one-year warranty.
APPLICATIONS
● HVAC economizer control
● Managing energy systems
● Facilitating ASHRAE standards for environmental control
2%, 3%, and 5% Accuracies
