The basic structure of the air sampler takes you to know it

The air sampler, also known as the aspiratory smoke fire detector or air sampling fire detector, is to analyze the air inhalation detector in the protected area through the air sampling tube to carry out early warning
of fire.

The air sampler system includes detectors and sampling network tubes
.

The detector is composed
of suction pump, filter, laser detection cavity, control circuit, display circuit and so on.

The suction pump continuously collects air samples from the protected area and puts them into the detector
through the sampling pipe network composed of PVC pipe or steel pipe.

The air sample passes through the filter assembly to remove dust particles and enters the detection chamber, which has a stable laser light source
.

Smoke particles scatter the laser, and the scattered light causes the highly sensitive light receiver to produce a signal
.

After systematic analysis, the photoelectric conversion is
completed.

The smoke concentration value and its alarm level are displayed by the
display.

The main machine transmits electrical signals to the fire alarm control center and the centralized display device
through the relay or communication interface.

The main part of the instrument is composed
of diaphragm pump, regulating valve, buffer, flow meter, processor and so on.

The new chip machine is used for circuit timing and power control
.

Its compact structure and stable performance, small size, light weight, easy to carry, wide sampling range, can be matched with a variety of absorption tubes, but also with a variety of absorption tubes, but also with a variety of solid adsorption tubes matching, is a small domestic Guangpu portable atmospheric sampler instrument in the more practical air sampler
