HW group: RTU-HTemp T3411

Temperature and humidity sensor with LCD and Modbus RTU

The RTU-HTemp T3411 is based on the T3411 transmitter from COMET SYSTEM. It measures temperature from −30 to +80 °C and relative humidity from 0 to 100% RH. Its integral probe measures the ambient conditions at the installation point, while the LCD displays readings locally.

RS485 with Modbus RTU connects the sensor to a compatible monitoring system such as a Perseus unit. It also calculates values including dew point from temperature and humidity. Power is supplied at 9–30 V DC. The electronics enclosure is rated IP65 and the probe IP40; outdoor installation therefore requires suitable protection of the probe from water.
