application

The transmission signal of the transmitter is compatible with electronic analog control, DDC/PLC control, and system automatic control. Meet the control requirements of the ventilation system and comply with ASHRAE62-1989

introduce

The CDD carbon dioxide transmitter uses infrared technology to monitor CO ₂ content. The monitoring range is 0-2000ppm and outputs a linear proportional signal, 4-20mA or 0-5VDC. Optional LCD display, relay, and 0-10VDC voltage output. It is very convenient to program and configure control parameters using the keyboard. Note that the high and low ranges of the output signal can be arranged. If 4-20mA is used to represent other contents such as 800-1000ppm, it can be achieved by changing the parameter settings.

Installation Introduction

Indoor detectors can be directly installed in standard electrical burial boxes. The installation position should be 5 inches away from the ground. It is best not to install sensors in doorways, windows, air switches, or other places that anticipate air interference. The duct type sensor can be installed outside the return air duct and inserted into the duct through a sampling tube for sampling and monitoring. In order to prevent reading errors caused by gas entering the control box due to wiring reasons, foam plugs are provided at the wire interface of the housing. Install sensors on straight sections of the pipeline, at least 5 inches away from corners and interference caused by air. Do not place the sensor in a place that is shaking or experiencing sudden changes in temperature.
