1Online dust detector with switch quantityWorking principle
During the transportation of gas-solid two-phase fluids containing dust particles, the collision and friction between dust particles and dust particles, as well as between dust particles and the inner wall of pipelines, will cause the dust particles to carry charges and form an electrostatic field. When charged dust particles pass through the measuring electrode, positive and negative charges are induced by the measuring electrode, and the charges form a current signal during the transfer motion; The magnitude of this AC signal is directly proportional to the mass content of dust. By further amplifying and processing this electrical signal, the dust concentration (mg/m3) can be measured.
IIOnline dust detector with switch quantityProduct Features
1. Using the principle of charge induction to measure dust concentration, with high measurement accuracy; By setting the upper limit alarm value of dust concentration through software, when the measured value exceeds the upper limit value, the CPU automatically compares and generates a switch signal, which is output to the upper computer for alarm. When the dust concentration recovers, the alarm is automatically released without manual reset.
2. Integrated structure, long current signal transmission distance, strong anti-interference ability.
3. The measuring electrodes are made of imported protective materials, which improve their ability to withstand high temperatures, corrosion, and adhesion, reduce cleaning and maintenance, and extend their service life. Improved product quality.
4. The airtight connection of the sensor body strictly prevents the leakage of the measured gas and the outward impact of the measuring electrode due to pressure, ensuring the safety of the transmitter and staff.
5. DC24V non-polar power supply, using industrial four wire power output, low-power operation, improves the safety of this product and on-site use.
