Amphenol Advanced Sensors T8700 Relative Humidity & Temperature Transmitters

Amphenol Advanced Sensors Telaire T8700 Relative Humidity and Temperature Transmitters are engineered for HVAC control applications and use an Amphenol ChipCap Sensor that provides quick and simple field replacement. The sensor bypasses the need to return the complete transmitter for recalibration. Amphenol Advanced Sensors Telaire T8700 Relative Humidity and Temperature Transmitters offer ±2.5% accuracy and user-selectable standard analog outputs. The series offers 0 to 5V, 0 to 10V, and 4mA to 20mA versions. The user can make temperature measurements via the active signal conditioned output as well as the standard passive 10K Type II thermistor. These transmitters come in two sizes to suit the European and US markets and include display and non-display options.
