CTRTA
CO2 and temperature transmitter suitable for wall mounting
Wall sensor
Good long-term stability
RBC algorithm
Very high accuracy
Robust design
The CTRTA transmitter are intended for wall mounting in HVAC systems. The sensors are mounted in the cover part of the casing.
Easy mounting
Cover of the seonsors is easy to detach from the back by means of snap-in grips and detachable terminals. Furthermore, no cables have to be disconnected, simplifying service and replacement.
RCBC algorithm
The transmitter is equipped with a function that can be activated to achieve a more stable CO2 level in a room that is not used for parts of the day.
Automatic Calibration
The transmitters have automatic calibration. This means that manual recalibration is not required during the lifetime of the transmitter.
The carbon dioxide level gives a direct indication of the indoor air quality. This information can be used to control ventilation with high precision and improve the air quality. By increasing the supply air only when necessary, it is possible to minimise energy costs. The transmitter is especially suited for environments such as cinemas, schools, hospitals, conference rooms, assembly halls, etc.
CTRTA wall transmitters combining measurement of CO2 level and temperature in the same casing. Built-in CO2 sensor has working range 0...2000 ppm and output signal 0...10 V, and built-in temperature sensor (working range 0...50°C) has output 0...10 V and PT1000. The transmitter have automatic calibration meaning that manual recalibration is not required during the lifetime of the transmitter. The sensors are mounted in the cover part of the casing and the cover is easy to detach to facilitate easy mounting. No cables have to be disconnected making both servicing and replacement simple.
Model CTRTA-D have an LCD display showing carbon dioxide concentration and temperature in an alternating series.
