The RHT Climate transmitter has an integrated temperature and relative humidity sensor on the wall mounted housing, or at the end of a duct mounted probe. The Stainless Steel probe is available in 150, 250 and 400mm length probes. All RHT Climate transmitters are available with 2 analogue outputs configurable by the NXperience software with options for 4-20mA or 0-10V outputs. Unit with the backlit LCD display can also be configured using the buttons on the unit. A Modbus option with additional psychrometric data is available for networking units via an RS485 connection and can also be collected via a USB connection for configuration. The RHT Climate is more precise, versatile and provides more psychrometric information than the other RHT transmitters.
RHT Climate Transmitters Wall Mount (WM) and Duct Mount (DM) models incorporate high-precision, stable sensors for measuring temperature and relative humidity. Because they are microprocessed device, they can be fully configured via a USB or RS485 interface, using command Modbus RTU. NXperience allows for configuring all transmitter outputs and ranges.
Apart from the temperature and relative humidity values, which are read directly from the sensor, the transmitter calculates the value of the following psychrometric properties
Any variable read by the sensor, or calculated by the device, can be transmitted via one of the two available analog outputs as a 0-10V or 4-20mA output. The user is also allowed to configure the electrical operating level of each output. Two digital outputs with alarm or control functions can be related to any variable read or calculated by RHT Climate Transmitter. The following options are also available:
