Tunnel Carbon monoxide/Visibility detector sensor

1.Product

Tunnel CO/VI detectors are designed to effectively monitor tunnel visibility and CO concentration around the clock so that fans can be started in a timely manner for forced ventilation and other corresponding measures to provide decision-making basis for tunnel ventilation and safe road traffic.

2.Options

1) Free software platform for data management.

2) Provide multiple communication options. Supports standard RS485/4~20mA communication and is compatible with standard MODBUS communication protocol.

3) The nitrogen oxide detection function can be expanded according to specific needs.

4.Performance

The tunnel COVI detector works according to the transmission principle. The transmitter/receiver and reflector are installed relative to each other. After being fixed and aligned using a bracket, the highly focused beam emitted by the optical component becomes a detection beam. The installation distance is 3 meters apart (double optical path to and from, actual detection The optical path is 6 meters). After the attenuation of the optical signal by the atmospheric channel, the signal obtained by the receiver is processed by the processor and becomes the measurement value.

The intelligent detector has a built-in compensation function. When the optical lens is contaminated, it can automatically perform gain compensation, thereby ensuring a long maintenance cycle.

5.Feature

1) The detector has a built-in compensation function, which can automatically perform gain compensation when the optical lens is contaminated, thereby ensuring a longer maintenance cycle.

2) Visibility (VI) and carbon dioxide (CO) can be measured simultaneously or separately.

3) High-resolution visibility measurement, the measurement is completely unaffected by other stray light sources.

4) Rugged appearance, designed for the harsh environment of tunnels, effectively preventing environmental or vibration factors from being impossible to measure.

5) The instrument comes with status display, fault alarm and data storage functions to facilitate debugging and equipment maintenance.

6) Using microprocessor technology, it operates completely digitally.
