Concentration Transmitter with two Relay Outputs ((0 to 10000ppm)
The CO2 - carbon dioxide level is recently regarded as an important parameter that substantially determines the quality of the interior climate. Especially in buildings where many people gather, such meeting rooms, hospitals, schools, cinemas, theatres and care centres. With the help of CO2 sensor engineers, technical advisors, environmental experts and health specialists can optimize the ventilation for creation of a healthy interior climate.
Method of CO2sensor multipoint calibration leads to an excellent accuracy measurements of CO2in 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.
|The Sensor measures:||CO₂ (Carbon Dioxide)|
|Power Supply:||9-30 Vdc|
Transmitter is equipped with two relay outputs for alarm indication or control of external devices. For each relay setting of delay, hysteresis, audible alarm is enabled.
Parameters are easy adjustable from regulator keyboard or from the computer.
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.
