Telaire T8700 Relative Humidity & Temperature Transmitter

Telaire T8700 Relative Humidity Transmitter

Relative Humidity and Temperature transmitters for building automation control.

Control of Relative Humidity can help prevent condensation in the building envelope and mechanical systems. Relative humidity can be used to increase comfort levels and save energy by reducing the need to heat or cool the air by a few degrees.

The new transmitter uses Advanced Sensors’ own ChipCap sensor that has very fast response times and long-term stability. The plug in ChipCap sensor module also allows quick and simple field replacement negating the need to replace or return the complete transmitter for recalibration. The transmitter has an accuracy of +/- 2.5% and has standard analog outputs that are all user selectable, they include 0-5 v, 0-10v, and 4-20mA. Temperature measurements can be made by the active signal conditioned output as well as the standard passive 10K Type II thermistor.

The T8700 relative humidity transmitter is available in two sizes to suit the European and US markets as well as display and non-display options. All models are easy to install, through a two-piece enclosure and simple terminal blocks
