Does the Duct-Mounted Humidity Sensor Have an RS-485 Modbus Output?
The RHT Climate duct-mounted humidity sensor is available with an RS-485 Modbus output option. For the duct-mounted humidity transmitter, we generally keep the fully equipped version in stock, featuring 2 analog outputs, 2 digital ON/OFF outputs for alarm control, and an RS-485 Modbus output.
The duct-mounted humidity sensor is available in both display and non-display versions with 3 different probe length options: 150 mm, 250 mm and 400 mm.
Our company offers a wide range of humidity sensors and humidity transmitters. We can help you select the most suitable solution for your application and recommend the right humidity sensor product.
Can We Configure the Desired Scale for the Analog Outputs of the Duct-Mounted Humidity Sensor?
The analog outputs of the RHT Climate duct-mounted humidity sensor can be scaled as required. For example, you can configure the sensor so that the 4-20 mA output represents a range of 10-90% RH, or configure the 0-10 VDC output to represent a temperature range of 0-80 ºC.
What Is the Operating Temperature Range of the Probe for the Duct-Mounted Humidity Sensor?
The RHT Climate duct-mounted humidity sensor can operate between -40 and +100 ºC and can measure humidity within this temperature range. This is the operating temperature range of the humidity sensor probe. The operating temperature range of the electronic housing located outside the duct is -40...+60 ºC.
