TASSERON EuroSeries Duct Carbon Dioxide Transmitter Sensors Installation
Guide

GENERAL
High quality duct mounted CO2 sensor with options for Relative Humidity (RH) and Temperature (T) outputs in the NEMA 4X Euro enclosure, equipped with hinged cover and tool-free Quick Connect wire terminals.
These sensors are designed as a CO2 & temperature or as a combination sensor with available CO2/RH/Temp measurements. Available with 0-10V standard output(s), with additional option for passive temperature NTC or RTD elements.
Dual channel technology and a solid state infrared source ensures long lifetime, excellent accuracy and repeatability with low drift and quick start up
NOTE: Rough handling and shipping reduces the accuracy of the sensor. Full accuracy is restored after the device is powered up for 250 hours non- stop.
Avoid strong mechanical stress and improper handling. The cable gland and housing cover must be screwed tightly against gas penetration, to avoid incorrect measurements

DISPOSAL
At the end of their useful life the packaging and product should be disposed of according to local waste guidelines.
| wiring run | maximum length |
|---|---|
| sensor to controller | 200 m (660 ft) |
NOTE: Installation of the sensor near high EMI-emitting devices may
lead to faulty measurements. Use shielded wiring in areas with high EMI. Keep
15 cm (5.9’’) min. distance between sensor lines and 230 Vac power lines.
Use two transformers: one for sensors and actuators and one for the controlle

MPORTANT: For failure-free operation and performance according to specifications, it is essential that the supply GND and the measurement GND be wired separately!
Shown with optional mounting flange and without 1/2” NPT conduit adapter
