European sizes (shows temperature in °C)US sizes, both display and non-display Multi Measurement Display versions scroll between % Relative Humidity and Temperature (°C or °F).. Unsurpassed Sensor Performance Telaire T8700 utilizes a rugged capacitive sensor that provides full-scale 0-100% RH measurement with unsurpassed response times, linearity and stability. Recovery to condensation and chemicals is excellent and an integrated filter helps ensure long life. All sensors undergo intensive digital calibration, certified against a primary **NIST reference standard. NIST certificate is available at additional cost (part no. 3PTCERT). Maximum Flexibility Telaire T8700 is designed to be highly configurable in the field or in your warehouse. By minimizing the necessary number of configurations, Telaire reduces distributor inventory costs and provides maximum flexibility to the installer. All versions feature field- selectable outputs (0 to 5V, 0 to 10V, 4 to 20mA) and a passive and 10K Type II thermistor. Signal-conditioned temperature is scaled from 32°F to 122°F (0°C to 50°C) and Relative Humidity is scaled over 0-100%. Rugged, Attractive Enclosures All Telaire T8700 feature rugged flame retardant, UL-94V ABS plastic. Special care has been taken in the design of the wall mount enclosure to provide enhanced airflow, increasing sensor response time and virtually eliminating the potential of "self-heating" by transmitter electronics that can lead to decreased accuracy measurements. Simple, Fast Installation All Telaire T8700 models feature a two piece enclosure with the back plate including terminal blocks eliminating the need to wire in a confined space and allow the unit to be pre-wired separate from the electronics. This is an especially attractive feature in unfinished construction, where exposed sensors and electronics could be damaged by moisture, drywall dust and paint. Lowest Cost of Ownership With a two-year warranty*, simplified inventory management, reduced installation times and field- serviceability, Telaire T8700 is a standard in reduced cost of ownership and performance-to-price ratio. *Transmitter only, one year warranty on replaceable sensor. *NIST/NPL certificate available on complete transmitter at extra cost.

European wall mount dimensions Telaire T8700 is fast and simple to install; the wiring diagram label shown is fixed to the inside of the back plate, making it easy to read and reducing the risk of miswiring. After wiring is complete, the front part of the enclosure, including the electronics, can be simply snapped on and held with a single safety screw. US wall mount dimensions

  • 0 to 10 V (100 W output impedance) and
  • 4 to 20mA (R L maximum 500 W) available simultaneously
  • Digital to Analog Error ±1% Enhanced Field Serviceability The T8700 series features a field-replaceable Relative Humidity (RH) sensor tip module that allows the end user to replace the sensor on-site while maintaining ±2.5% RH accuracy. The user simply powers off the unit, installs the new sensor module and powers back the unit. This virtually eliminates the need for time consuming and costly factory calibration, while reducing downtime during service intervals to near zero. Replaceable,humidity sensor. Specially designed hydrophobic filter to prolong sensor calibration life. AAS-920-543C-03/2014 www.amphenol-sensors.com © 2014 Amphenol Corporation. All Rights Reserved.
