TC-YDG online electrostatic smoke concentration monitor
(Suitable for continuous monitoring of pipeline dust in harsh production environments)
1、 Product Overview(Suitable for continuous monitoring of pipeline dust in harsh production environments)
In the production process of modern industry, due to process requirements, the application of dust meters is becoming increasingly popular, and the performance requirements for them are also increasing.
TC-YDGThe series dust concentration detector adopts a high temperature and high pressure resistant design, suitable for industrial production environments in China. The integrated, two-line structure makes installation and use extremely simple, and can easily connect to users' automated management systems. Real time monitoring of the working conditions of upstream equipment, achieving early alarms, facilitating maintenance and repair of upstream equipment, avoiding waste and unnecessary damage to downstream equipment. The application of dust concentration detectors can play an auxiliary role in the energy-saving and efficiency enhancing process implemented by enterprises.
2、 Working principle
TC-YDGThe series dust concentration detector adopts reliable electrostatic measurement technology. When the airflow containing dust particles in the pipeline passes through a fixed sensor, the weak current generated by the movement of the dust particles is collected by the sensor and transmitted to the transmitter. After being filtered, amplified, and processed by a transmitter, it becomes an output value that is linearly related to the dust content.
3、 Characteristic advantages
1 TC-YDGseriesThe dust concentration detector is an integrated structure composed of a sensor unit and a transmitter unit
The two dedicated sensors are passive and without electronic circuits. High sensitivity, unaffected by vibration, no dust contamination, high reliability, and long lifespan.
The current signal output by the transmitter is electrically isolated from the sensor unit, achieving interference free transmission of the output current signal.
4-wire system (4-20mA) current signal output, strong anti-interference ability, easy to transmit over long distances, 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, capable of replacing sensor units and transmitter units independently.
6. Long life design, all metal casing and connectors.

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. (i) Cover with the sealing cover.
5、 Installation
Special attention should be paid during installation: the direction of fluid movement should be consistent with the direction indicated by the arrow on the sensor.
The sensor needs to be installed on a metal pipeline (please consult the manufacturer for non-metallic pipeline installation).
2 should be installed vertically as much as possible in horizontal pipeline sections, and in case of special circumstances, it can also be installed horizontally.
The installation position should be selected on a straight pipeline section that is 5 times the diameter of the valve or elbow.
Drill a hole on the pipeline (with a size of 120mm) and weld the base onto the pipeline, ensuring no leakage.
The 5 sensors are connected to the base via flanges, and the base and sealing gasket are provided by the manufacturer.
The connecting cable is a 2 * 1mm ² shielded cable, and the shielding layer should be well connected to the transmitter housing.
The external cables should be fixed nearby to prevent wind and rain from swinging back and forth, which may cause mechanical damage to the transmission wires.
6、 Application
TC-YDGThe series can be applied to industrial purposes such as ironmaking, power generation, pharmaceutical machinery, chemical industry, building materials processing, cement manufacturing, etc. Typical applications include detection of bag filter bag damage in bag filters, recovery of powdered materials, monitoring of total process transportation, monitoring of emissions from fuel boilers and other productive particulate matter.
