infrared carbon dioxide detector KB-502 - pipeline type

infrared carbon dioxide detector KB-502 - pipeline type
Product Detailed
Carbon dioxide detector KB-502 NDIR infrared CO2 sensor CE certificate

Carbon dioxide detector KB-502 is applied to detect the carbon dioxide concentration in industrial, agricultural or dwelling environment, and monitor the interior temperature and humidity. 1~3 ways 0~10V analog quantity and three-way relay electronic contact signals output, can control the controlled devise directly or be  transmitted in to any electronic analog controllers. Autonomous system of DDC/PLC controller or draft apparatus can monitor the draft system based on the detection target value (CO2 concentration, temperature and humidity).

 

KB-502 has RS-485 communication interface which can connect to the computer or other control system with independent addressing, to accomplish the intelligent management for the draft system of each room.

 

Widely be used for ventilation controlling in industrial and agricultural environment (such as workshop, greenhouse, clean room, etc), public place (such as hotel, exhibition hall, hospital, department store, bar, restaurant, airport, railway station, cinema, etc) and other place (villas, office, meeting room, class room, etc).

 

Features

• Real-time monitor the CO2 concentration, detecting range 0~20,000 PPM (0~50,000 PPM is optional);

• USA Telaire sophisticated NDIR infrared self diffusion sensor which has long performance life of 15 years;

• ABC Logic self-setting patented technology, user need not to set it repeatedly during long time usage;

• Microprocessor-based programmable on-site settings with rapid response

• Three-wire system 4~20mA standard signals output and long-distance transmission;

• PC/ABS high quality fire retardant material housing;

• CE standard certificate.
