T6615 Telaire - Dual Channel CO2 Sensor Module for Environmental Monitoring in Buildings





Press Release

MORE Gas Modules

Willow Technologies Limited introduces the Amphenol Telaire T6615 dual-channel CO2 module, designed to meet the volume, cost and delivery expectations of original equipment manufacturers (OEMs).

As a vital part of building monitoring systems, the T6615 module allows building owners and managers to quickly, easily and efficiently monitor air quality and stay within regulation.

Said Martin Pearce, Marketing Director, Willow Technologies Limited, “The T6615 module is a truly unique solution, one of the only dual channel small modules on the market, the design is based on 15 years of manufacturing and engineering expertise and provides an accurate, cost effective solution for OEMs.”

The T6615 is a dual channel Non Dispersive Infrared (NDIR) module, with a CO2 channel that measures gas concentration and a reference channel that measures the sensor signal intensity. The reference channel allows the module to recalibrate automatically and is beneficial in applications where CO2 levels do not drop to outdoor levels on a daily basis. The module has a measurement range of up to 50,000ppm, an accuracy of 75ppm or 10% at reading (whichever is greater). Stability over 10 years service life is better than 5% of full scale. It measures 57 x 35 x 15mm.

Applications include monitoring indoor environmental air quality in call centres, 24-hour retailers and any environment where there is no baseline to trigger recalibration. The T6615 is a flexible CO2 sensor platform designed to interact with other microprocessor devices and may be field calibrated. It performs periodic self-calibrations using the reference channel. The self-calibrations are approximately every 24 hours but can be initiated manually.

“The dual-channel optical system and three-point calibration process allow for enhanced stability, accuracy and reliability” concluded Pearce.
