High Accuracy RH/T Transmitter

High Accuracy RH/Temperature/Dew point HTX1R/HTX1W/CPX1R/CPX1W/FLPHT Series Transmitters measures relative humidity and dry-bulb temperature by default with field programmable setup option for analog or network communication output. The transmitter provides an efficient environmental monitoring and control solution for HVAC and building automation applications. Configurable measurement values include Relative Humidity, Absolute Humidity, Dry-Bulb Temperature, Wet-Bulb Temperature, Dew Point Temperature, and Enthalpy. Adjustable output ranges and network accessible data points provide maximum application flexibility. The transmitter come with Wall mount and Remote probe options.

The CPX1R/CPX1W Series include an additional Pt1000 sensor input for monitoring cooling pipe temperature. The transmitter continuously compares the measured pipe temperature with the calculated dew point derived from ambient dry-bulb temperature and relative humidity. When the pipe temperature falls to or below the configured condensation threshold (Dew Point + Condensation Differential), the relay output is activated. This functionality provides reliable condensation detection and alarm generation, helping to prevent moisture related damage in critical environments.

The HTX1R/HTX1W/FLPHT Series include an additional digital input for monitoring external alarm or status signals from third-party equipment. The input accepts a potential-free (dry contact) signal and continuously monitors contact status. The digital input can be configured to activate the relay output.
