The AE3020 ducted temperature and humidity transmitter is an ideal solution for accurately measuring relative humidity and temperature in HVAC applications at a reasonable price. It is equipped with a sintered filter cap with waterproof and breathable functions that can be used in severely polluted environments. It can be single humidity or temperature humidity integrated, outputting current signals.
The selection of high-quality integrated digital temperature and humidity sensor DHT22 ensures excellent long-term stability, low hysteresis, and strong resistance to chemical pollution of the transmitter. This transmitter has excellent repeatability. The integrated humidity sensor can also be quickly replaced without calibration, and the cost is relatively low.
Typical applications:
Building Automation
Climate and Heating Automatic Control
Climate stations in museums and hotels
Closed loop control in HVAC systems
characteristic:
Excellent performance price ratio, good long-term stability
Moisture resistant, equipped with breathable sintered filter caps that can be used in various harsh environments
Full range temperature compensation, more accurate measurement of high and low temperature humidity
Digital calibration, wide temperature and humidity measurement range, extremely high reliability
Easy to maintain, temperature and humidity sensor probe can be quickly replaced without calibration
