KCS571

Infrared CO2 Gas Sensor Module

1. Brief Introduction

SW711 is a gas sensor based on the principle of NDIR infrared absorption, suitable for testing the gas concentration of various heteronuclear molecules in industrial applications.

SW711 adopts a patented optical cavity, imported light source and dual-channel detector to achieve dual optical path reference compensation in space. SW711 has good selectivity, no oxygen dependence and long life.

The SW711 has UART, 4 to 20mA outputs, 485 outputs, etc., and provides customers with a manually calibrated MCDL pin. It is convenient for customers to use outdoor free-flowing clean air to calibrate the sensor module relative to zero.

SW711 adopts diffusion ventilation method, and the response time is less than 30 seconds.

The SW711 is available in a variety of packages that can be customized to meet customer needs. There are three common packages: package one, package two (six pins 4-20mA), package three (seven pins 485 interface), of which package two and package three are the same size.

5.Installation instructions

The sensor mounting thread dimensions refer to the block diagram.

6.Matters that should be paid attention to in maintenance

The sensor should be calibrated regularly, it is recommended that it be no more than 3 months, and calibration is not required on the long-term operation side if automatic calibration is turned on

Do not use the sensor for a long time in an environment with a high density of dust

Please use the sensor within the range of the sensor's power supply

7.Ordering instructions

In order to be able to purchase the specific specifications required, please provide the following information

1) Sensor name, 2) Sensor range 3) Sensor measurement accuracy and output mode, etc

For example, SW711, 50000ppm, 4-20mA output

9.Precautions

1 In environments with EMC issues, shielded cables must be used.

2 When the module is cold started, the warm-up time should not be less than 2 minutes.

3 The sensor should be calibrated regularly, not more than 3 months is recommended.

4 Do not use the sensor for a long time in a dusty environment.

5 Please pay attention to the wiring of the positive and negative terminals of the power supply and the signal output terminals. Do not connect backwards.

6 High concentrations of chemical contamination can lead to the destruction of the sensor polymer layer, therefore, the product should be stored and used away from the source of chemical contamination.

7 Please refer to the relevant national product installation standards for the installation process.
