The HT82 channel temperature and humidity transmitter has a MODBUS/RTU-RS485 serial port. The channel humidity and temperature transmitter is used to measure the temperature (Celsius measurement unit) and ambient humidity (relative humidity in percent) of the air conditioner channel. The channel temperature and humidity measurement device is custom-made with two relay outputs, LCD display, two voltage output channels 0 to 10 volts (0 to 10V) and two current output channels 4 to 20 milliamps (4 to 20mA) (of course, at the same time, you can use used one of the voltage or current outputs). Analog outputs work independently and can be set to a quantity with desired values. Analog output values can be adjusted by software. The temperature and humidity sensor is a digital channel and does not require calibration and is made in Switzerland.
Duct temperature and humidity sensor
- The accuracy of the humidity sensor is ±2% (between 0 and 90 percent), the measurement range is 0 to 99.9 percent.
- The accuracy of the temperature sensor is ± 0.2 degrees Celsius (between 0 and 90 degrees), the measuring range of the sensor is -40 to 80 degrees (pay attention to the environmental conditions of the device)
