Product details
TC-YDB (wall mounted) electrostatic dust concentration monitor
1Product Overview
In the production process of modern industry, due to process requirements, the application of dust meters is becoming increasingly widespread, and the performance requirements for them are also increasing.
TC-YDB(Wall mounted)The series dust concentration detector adopts imported high-precision anti-aging sensors, intrinsic safety explosion-proof structure, and wall mounted stainless steel box design. It is suitable for various working environments that generate dust, such as production workshops, material storage warehouses, material yards, offices, belts, and wind power feeding. The two-wire 4-20mA output signal can be easily integrated into the user's automation management system. Real time online monitoring of dust environmental conditions, timely alarm or activation of dust removal and reduction equipment, to control the dust content in the environment within the standard range and reduce the damage of dust to human health and the environment. Dust concentration detectors are playing an increasingly important role in the energy-saving and efficiency enhancing processes implemented by enterprises.
It can be widely used in various industrial applications, such as ironmaking, power generation, pharmaceutical machinery, chemical industry, building materials processing, cement manufacturing, etc. This includes monitoring the emissions of office dust, production workshop dust, process transportation dust, material yard dust, and other generated dust.
2、 Working principle
TC-YDB(Wall mounted)The series dust concentration detector adopts accurate and reliable AC electrostatic measurement technology. Under the action of the airflow generated by the auxiliary gas source, the dust particles in the measured environmentEntrance of dust concentration detectorImport via electrostatic sensor toDust concentration detector outletThe weak current generated by dust particles in this motion is collected by sensors and transmitted to transmitters. After being filtered and amplified by the transmitter, it is processed into a 4-20mA standard output value that is linearly related to the dust content.
3、 Characteristic advantages
1TC-YDB(Wall mounted) seriesThe dust concentration detector is a compact wall mounted box structure composed of a sensor unit, a transmitter unit, an auxiliary airflow generator, and a stainless steel box.
2. The dedicated sensor is a passive type without electronic circuits. High sensitivity, unaffected by vibration, no dust contamination, high reliability, and long lifespan.
3. The current signal output by the transmitter is electrically isolated from the sensor unit, achieving interference free transmission of the output current signal.
4. Two wire (4-20mA) current signal generation and output, strong anti-interference ability, easy to transmit over long distances, and no special requirements for transmission wires. The output current is linearly related to the dust concentration, which facilitates subsequent PLC data processing.
5. Modular design allows for individual replacement of sensor units and transmitter units.
6. Long life design, all metal casing and connectors.

Sensor unit
Specialized sensors cannot be replaced by other alternatives.
Transmitter unit
1 standard two-wire transmitter, 24V circuit power supply, 4-20mA current signal output, aluminum alloy shell is waterproof.
2. Open the sealing cover to see the wiring terminals. The signal cable is fixed to the terminal post through the wiring hole on the transmitter housing (wiring is not positive or negative). Turn the locking screw of the wiring hole to the appropriate position to prevent water from entering, and finally cover the sealing cover for secondary sealing.
