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.
