Description
The GS-CD-T51 series is a cost effective, high performing, wall-mount CO2 transmitter (optional Temperature Sensor) for the building controls industry. The "L" option adds a multi-coloured LED indicator of CO2 thresholds to displayair quality in enclosed spaces (i.e. school classrooms, offices, gymnasiums, theatres etc.). The unit comes complete with“Automatic Background Calibration” software to reduce drift to better than +/- 20ppm per year.
This sensor is compatible with the large majority of our Data Logger and Data Acquisition system ranges.
This is the Dual Analogue Output version (CO2+Temperature), with LED Indicator's.
Features
- 0-10Vdc or 4-20mA output for Co2
- Thermistor or Analogue output for Temperature
- Mounting plate with 2 piece terminal blocks
- 15 year calibration interval
- 5 Coloured LED on T51-EL version
- Wall mounting
- Monitors CO2 over range 0 to 2,000 ppm
- EL version (temperature 0-50'C)
- 24Vac/dc Power supply
- Digital UIP interface (RS-232 TTL Level)
