The slip switch and speed detector are a new device used to detect the speed of conveyor belts, which can detect the speed in real time. They have been widely used in conveyor systems and provide a reliable detection method for the safe operation of conveyor belts< Br/>
It needs to be horizontally installed on the conveyor bracket between the upward and downward tapes, so that there is a certain pressure between the contact wheel and the surface of the tape to prevent accidental action caused by contact wheel jumping. When the contact wheel drives the inner pulse disk with the operation of the tape machine, the magnetic stress signal of the sensor is input into the control circuit when the pulse disk rotates, amplified, and then counted. Compare the baseline value with the predicted value to determine the speed of the tape, such as slipping or speeding at normal speed. At the same time, the execution circuit outputs the corresponding switch signal< Br/>




Structural features
This machine is composed of a contact wheel, a pulse disk, an electronic pulse switch, a housing, etc. The contact wheel is made of die cast aluminum, and the surface is milled with grooves for grinding and slipping. The housing color is cast with aluminum, and the connection is equipped with a sealing ring, even if the machine reduces weight and has good waterproof performance< Br/>
The internal switch of this machine adopts a normally closed type. If the speed is lower than 80% of the normal speed, it can trip or stop< Br/>




Technical parameters

Environmental temperature: -30 ℃~+60 ℃

Relative humidity: not more than 80%

Contact capacity: AC220V/500MA

Speed measurement range: 20~999r/min

Switch Open: Normally Closed (or Normally Open)

Weight: 3.5KG

Reliability: 6-power start stop with>10

Applicable Place
The slip switch is suitable for real-time detection of conveyor belt speed in industries such as coal mining, power, and grain


Installation method

1. It can be installed in any position of the tape machine, as long as it can ensure close contact between the contact wheel and the tape

2. Installation should ensure that the axis of the contact wheel is parallel to the tape, and the direction of movement is parallel to the release of the tape during operation
3. Users can configure installation brackets according to their own tape machine size and height, and ensure that the contact wheel and tape surface are within the elastic range during installation< Br/>
