“Precise data on humidity and temperature is vital for efficient and safe HVAC control,” says Chris Ranwell, Global Product manager for the Advanced Sensors business, “Condensation can lead to mold and associated building decay and health risks. Moreover, considerable energy savings can be made by closely controlling the relative humidity, as this can prevent unnecessary air cooling. The new Telaire T8700 complements our line of award winning Ventostat’s for CO2 demand control ventilation and give customers simple low cost options for humidity control.”
The new transmitter uses GE's 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 eliminating the need to replace or return the complete transmitter for recalibration. The transmitter has an accuracy of +/- 2.5% and has standard analog outputs, including 0-5V and 4-20mA, that are all user selectable. Temperature measurements can be made by the active signal conditioned output as well as the standard passive 10K Type II thermistor.
The T8700 is available in two sizes to suit the European and US markets and is offered in display and non-display options. All models are easy to install, through a two-piece enclosure and simple terminal blocks.
