Overview

The TITAN TPVRCO2T range of room sensors provide CO2 measurement using NDIR technology for a range of 400 to 2000ppm and can be supplied with a 0-10V or thermistor temperature output.

There is also an option for a 0-10V Humidity output

Optional LED's can be added to provide status indication of the measured CO2 concentration levels.

The CO2 sensor employs Automatic Background Calibration (ABC Logic) to continuously adjust the calibration base to correct for changes in the background concentration levels and sensor drift.

The CO2 sensor calibration algorithm starts after the first 24hrs of operation and continuously monitors and automatically adjusts the sensor calibration over the life time of the product.

The ABC Logic self-calibration takes place over a 24 hour period of operation when the space being monitored is subjected to an unoccupied period and the background CO2 concentration is subjected to the prevailing external level.

The CO2 sensors use a silicon based technology to provide excellent stability and reliability. The sensors require very little maintenance with a recommended calibration interval of 5 years in normal HVAC applications.
