HNT000269, otherwise known as T3 dust sensor, is a kind of dust detection sensor from Carlo Gavazzi. It is designed for air velocity, air temperature and dust concentration measurement and displays relevant statistics. It is widely used for air quality and temperature control in industrial facilities. This paper will focus on its application field and work principle.

Application Field of HNT000269:

The main purpose of HNT000269 is to detect dust concentration in the air, so it can be extensively applied to industrial dust concentration monitoring, in areas such as woodworking, coal handling, chemical manufacturing, paper manufacturing, and food processing etc. It can also be used for particulate laden air volume measurement or air flow velocity monitoring. Moreover, the dust detection result can be used in air quality and temperature control of equipments in an industrial facility and to determine the dust concentration in the exhaust air of workshops.

Working Principle of HNT000269:

The working principle of HNT000269 is based on the optical measurement of dust particles in a specific optical path. Specifically, it uses a combination of a small fan impeller to draw in the air sample along with an infrared emitter and a photo detector which are arranged perpendicularly to each other, with the air sample drawn in by the fan passing along in between them. When the air sample passes through the air gap, it contains dust particles of different sizes which are illuminated by the emitter. This produces a differential shadow pattern on the photo detector which it then analyses for dust counts. Based on the count results from the photo detector, the dust particle concentration in the sampled air is determined.

Advantages of HNT000269:

The advantage of HNT000269 lies in its accuracy level. Its accuracy is much better than traditional measuring methods, which rely only on the detection and calculation of dust particles in the air, so it can give an extremely accurate estimation of the dust level in the air. In addition, it is easy to install compared to other dust detection sensors, as it doesn\'t need any external components or complex setup procedures.

Conclusion:

In summary, HNT000269 is a highly accurate dust detection sensor, which can accurately measure airborne dust concentrations and is suitable for industrial dust concentration monitoring. Its efficient design and installation make it a preferred choice for air quality and temperature control in industrial catering and ventilation applications.
