More About Duct Humidity
Air ducts are an unfriendly environment for control sensors. You need an air duct humidity sensor strong enough to withstand these dangers and sensitive enough to measure the humidity.
We offer 117 different control sensors to measure the humidity in your air ducts.
Without specific sensors monitoring the moisture and debris in your air ducts, you could find pollutants and mold growing in them. To ensure you do not have these problems, we work with top-rated manufacturers such as ACI, Belimo, Mamac, and Veris.
Working with these companies, we can maintain an accuracy of ±3% for the temperature and relative humidity of your air duct.
Additionally, we carry a Belimo air duct sensor with a BACnet or Modbus communication system. These communication protocols connect your HVAC to your network.
Belimo also manufactures 14 sensors with a plastic box housing. While metal is the standard material used in a duct, plastics are often less susceptible to rusting. Rusting air duct sensors are not uncommon.
Finally, our air duct sensors rely on two types of temperature & humidity signals.
The first is the Resistance Temperature Detector (RTD). The RTD uses a thin wire to detect humidity in the air duct. It then transfers the amount of moisture to a small electrical signal with a charge that ranges from either 0-10 VDC or 4-20 mA.
The second option is the thermistor. The device uses the same technique, except has a different metal to measure the humidity. The thermistor also sends an output signal to the HVAC system through a 0-10 VDC or 4-20 mA charge.
