4-20mA LCD Display Temp Humidity Transmitter For Greenhouse
4-20mA LCD Display Temp Humidity Transmitter For Greenhouse
Description
KTH500 temperature and humidity transmitters mostly uses the temperature and humidity integrated probe as the temperature measuring element, collects the temperature and humidity signals, and undergoes voltage stabilization filtering, operational amplification, nonlinear correction, V/I conversion, constant current and reverse protection, etc. After the circuit is processed, it is converted into a current signal or a voltage signal output that has a linear relationship with temperature and humidity, and it can also be output directly through the main control chip through the 485 interface.
