CO2 Concentration Transmitter w/Two Relay Outputs
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 the 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 to pollution and provides maintenance-free operation and excellent long-term stability.
Applications
- Building HVAC management
- Climate technology
- Schools, universities
- Meeting rooms, hospitals, cinemas, theatres
- Weather stations
Regulator Mounting and Connection
Regulators are designed for wall mounting. Device must be mounted on the plane surface to prevent its deformation. Mounting holes and connection terminals are accessible after demounting four screws in the corners of the box and removing the lid. There is recommended to use screws with a half-round head with cross-recessed screw ST 3.9 (DIN 7981). Lace the lead-in cable with an outer diameter of 3 to 6.5 mm through the glands at the case wall and connect them according to schematic below. Terminals are self-clamping and can be opened by a suitable screwdriver. For the opening, insert the screwdriver to a smaller terminal hole and lever by him. Do not forget to tighten glands and case lid with inserted packing after cables connect. Insert the attached plug in to unused cable glands too. Do NOT connect the regulator under voltage.
