More About Duct Humidity Sensors

WHY RELATIVE HUMIDITY SENSORS ARE SO IMPORTANT FOR HVAC CONTROL SYSTEMS?

There are a few key reasons why relative humidity sensors are so important for HVAC control systems, both for residential and industrial applications. First, relative humidity is a key indicator of indoor air quality. If the relative humidity is too high, it can lead to condensation and mold growth. Second, relative humidity can affect the efficiency of heating and cooling systems. If the relative humidity is too low, heat loss can occur. Finally, relative humidity can impact human comfort levels. If the relative humidity is too high, it can cause discomfort and respiratory problems. By monitoring the relative humidity, HVAC controls systems can help to ensure optimal indoor air quality and comfort levels.

WHAT SENSORS DO YOU NEED FOR A COMPLETE HVAC CONTROL SYSTEM?

There are many different types of sensors that can be used in HVAC control systems, but some of the most common ones include a temperature sensor, humidity sensor, pressure sensor, and airflow sensor. Other less common sensors that are sometimes used include air quality sensors, CO2 sensors, and occupancy sensors. In general, the more types of sensor data that a system can collect, the more accurate and effective the system will be at controlling the environment.

MORE ABOUT OUR DUCT HUMIDITY SENSOR SUPPLY

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, each air duct humidity sensor relies 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.
