Comet T8148 – CO2 Concentration and Temperature Transmitter with 4-20mA Outputs, Built-in Sensors

• CO2 concentration
• Temperature transmitter
• Built-in sensor 0 to 2000ppm
• 4-20mA Outputs
• The sensor is resistant against pollution and provides maintenance-free operation and excellent long-term stability
• With this sensor is the device able to meet the demanding requirements for outdoor use

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 as 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 CO2 sensor multipoint calibration leads to excellent accuracy measurements of CO2 in the entire 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 the aging of the sensor. The sensor is resistant against pollution and provides maintenance-free operation and excellent long-term stability.

Transmitter contains a microprocessor-based control circuitry in an ABS plastic case with connection terminals.

The CO2 concentration and temperature sensors are 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 and temperature values are converted to 4-20mA current outputs.

Applications

• Weather stations
• Schools, universities
• Building HVAC Management
• Climate technology
• Meeting rooms, hospitals, cinemas, theatres
