CO2 Concentration Transmitter with 0-10V Output, External Carbon Dioxide Probe, Cable 1m
A multiple-point CO2 and temperature adjustment procedure lead to excellent CO2 measurement accuracy over the entire temperature working range; this is a must for process control and outdoor applications. The dual wavelength NDIR CO2 sensing procedure compensates automatically for aging effects.
The CO2 module is highly resistant to pollution and offers maintenance-free operation and outstanding long-term stability. Measured values can be read in "SLOW mode" (filtered, averaged) or in "FAST mode" (current values without averaging). SLOW mode has advantages in applications like climate control because of filtering short time peaks. As an example exhaled air from an employee passing the sensor could affect the climate control negatively with a short response time because the control would trigger a change of the ventilation based on this one-time measurement. On the contrary in "FAST mode" no software filter is used for calculating the output value. This fact adds a noise of typ. ±30ppm which has to be considered in terms of accuracy. Of principle measurement is the measured value of CO 2 concentration depends on the value of air pressure - altitude at the installation site. For this reason, it is suitable for accurate measurement to set the altitude of the installation site by TSensor software.
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 against the pollution and provides maintenance-free operation and excellent long-term stability.
