The dust concentration detector is designed for high temperature and high pressure resistance and is suitable for various industrial production environments. The integrated, two-wire structure makes installation and use extremely simple and easy to access to the user's automated management system. Monitor the working conditions of the upstream equipment in real time, realize early warning, and facilitate the maintenance and repair of upstream equipment to avoid waste and unnecessary damage to downstream equipment. The application of the dust concentration detector can play an auxiliary role in the energy-saving and efficiency-enhancing process implemented by the enterprise.
working principle
The dust concentration detector uses the most reliable electrostatic measurement technology. When the airflow containing dust particles in the pipe passes through a fixed sensor, the weak current generated by the dust particles during the movement is collected by the sensor and transmitted to the transmitter. Filtered, amplified, and processed by the transmitter to become a standard output value that is linear with dust content.
Feature advantages
1. The dust concentration detector consists of an integrated structure consisting of a sensor unit and a transmitter unit.
2. The dedicated sensor is a non-electronic circuit, passive passive type. High sensitivity, free from vibration, no dust, high reliability and long life.
3. The current signal output by the transmitter is electrically isolated from the sensor unit to achieve interference-free transmission of the output current signal.
4. Two-wire system (4-20mA) current signal output, strong anti-interference ability, easy to transmit over long distance, no special requirements for transmission wires. The output current is linear with the dust concentration to facilitate subsequent PLC data processing.
5. Modular design, sensor unit and transmitter unit can be replaced separately.
Flame Retardant Science and Technology is to meet social security needs of production and life, to prevent fires and protect lives and property and developed a science. Flame retardant technology is the application in real life, it is a flammable material used to improve the combustion properties of flammable special chemical additives, are widely used in various types of flame-retardant decoration materials processing. Processed through the flame retardant material, fire in an attack by the outside world, can effectively prevent, delay or terminate the spread of fire to achieve the flame retardant effect. According to different criteria for the classification can be flame retardant into the following categories: according to fire-retardant elements contained in sub- Element can be contained by fire retardant into halogen flame retardant, phosphorus flame retardants, flame retardant nitrogen and phosphorus - halogen flame retardant, phosphorus - nitrogen flame retardants and other categories.
