CO2 concentration transmitter with 4-20 mA output T5145 is detrmined for duct mount. Transmitter contains a microprocessor based control circuitry in a durable plastic case with connection terminals.
The CO2 concentration sensor is built inside the case.
Large dual line LCD is an advantage. Display is possible to switch off. Computerized design ensures maximum long term stability and failure indication.
Measured CO2 concentration values are converted to 4-20mA current output.
Method of CO2 sensor multipoint calibration leads to an excellent accuracy measurements of CO2 in the entire of operating temperature range. With this sensor is the device able to meet the demanding requirements for outdoor use. The measurement principle is based on the NDIR principle with dual wavelength, which automatically compensates for aging of the sensor. The sensor is resistant against the pollution and provides maintenance-free operation and excellent long-term stability.
