Speed ​​probe CS-1-D-100-02-00,
CS-2-120-03, CS-3-100-04-02
The speed probe CS-1-D-100-02-00 adopts the principle of electromagnetic induction to realize speed measurement. A coil is wound around the front end of the sensor. Its outline drawing is shown in Fig. 1, and its installation is shown in Fig. 2. When the gear rotates, it passes through the sensor coil. The magnetic lines of force change, a periodic voltage is generated in the sensor coil, and the rotation speed of the gear can be measured by counting the voltage processing. The stainless steel sensor housing, the output signal is strong, anti-jamming performance, easy installation and use, can be used in the harsh environment of smoke, oil and gas, water and gas.

working principle
When used, a gear should be mounted on the shaft to be measured (the positive and the helical gears can be placed on the grooved disk), the sensor is mounted on the bracket, and the gap between the sensor and the gear tooth tip is adjusted to about 1 mm.
When the shaft rotates, it drives the gear to rotate. According to the principle of electromagnetic induction, a voltage pulse signal is generated at both ends of the sensor's internal coil. When the shaft rotates for one revolution, Z (number of teeth) voltage pulses are generated. This signal is input to the JX5031 tachometer. Set the number of teeth in the tachometer, the tachometer can reflect the rotation speed of the shaft will be converted into electrical signals for the counter to count the count, non-contact can measure a variety of magnetic materials such as: gear, impeller, with holes (or slots, Screw) Speed ​​and linear speed of the disc (or shaft).
The sensor has the advantages of small size, strong and reliable, long life, no need of power supply, etc., and can be matched with general speed instruments.
CS-2-120-03 Speed ​​probe When the metal tooth passes through the Hall sensor front end, it causes a magnetic field change. The Hall element detects a magnetic field change and converts it into an alternating current signal. The built-in circuit of the sensor amplifies and reshapes the signal. , Output a good rectangular pulse signal, measuring a wider frequency range, the output signal is more accurate and stable, easy to install, oil and waterproof, has been widely used in the field of electric power, automotive, aviation, textile, petrochemical and other speed measurement

Since beginning of 21st century, while global automobile industry flourished, the scrapped amount of used tires has grown rapidly.
The annual output of used tires is 9.5 million tons, and the recycling rate is less than 25%.
At present, China produces 100 million pieces of used tires every year, and recycling rate is only about 15%.
The tires are only 10-15% of the natural loss of rubber from the beginning to the end of use.
However, 90% of the tires and 100% of the tire frame materials are disposed and not recycled, which not only causes a lot of waste of resources, but also causes great harm to the ecological environment.
