A speed sensor is a sensor that converts the rotational speed of a rotating object into electrical output. The speed sensor is an indirect measuring device that can be manufactured using mechanical, electrical, magnetic, optical, and hybrid methods. According to the different signal forms, speed sensors can be divided into analog and digital types.

The speed sensor uses a magnetic sensitive resistor as the sensing element and is a new type of speed sensor. The core component uses a magnetic sensitive resistor as the detection element, and then undergoes a brand new signal processing circuit to reduce noise and improve functionality.

The sensing object is a magnetic material or a magnetic conductive material, such as magnetic steel, iron, and electrical steel. When a magnetic or magnetic material with protrusions (or indentations) on the object being measured rotates, the sensor outputs a pulse signal related to the rotation frequency to achieve the purpose of speed measurement or displacement detection.

The Hedeke gear speed sensor has the following characteristics:

-High sensitivity, high reliability, long lifespan, long triggering distance

-Signal triggered by iron (soft) magnetic material

-Capable of achieving long-distance transportation with strong resistance to electromagnetic interference

-Good impact resistance and earthquake resistance

Explanation of parameters for Hedeke speed sensor:

1. Gear size parameters: gear outer diameter: 99.3mm; number of teeth: 60; Modulus: 1.57 (The above dimensions are just one example, modulus can range from 0.5 to 2.)

2. When installing the sensor, make sure that the connection between the tail red LED and the root of the lead wire is perpendicular to the gear plane.

3. The sensor leads are: brown is the power cord; Black is the ground wire; Blue represents the signal output line. Due to its convenient installation and good universality, it has been widely used in various fields. Especially in low-speed or ultra-low speed non-contact detection, there is a characteristic that other sensors cannot achieve, which is that the magnetic electric sensor has a speed measurement range of 50-5000Hz. The detection distance is only 0.5mm, and the proximity switch cannot detect small mold teeth; In non-contact detection at medium and high speeds, it can directly replace Hall switches.

4. Capacitive: Capacitive sensors are available in two types: area change type and dielectric change type. The rate of periodic change in capacitance is the rotational speed. The measurement signal of rotational speed can be obtained through methods such as DC excitation, AC excitation, and using variable capacitors to form the oscillation slot circuit of the oscillator. Dielectric transformation type is composed of embedding a high dielectric constant movable plate between two fixed electrode plates of a capacitor. The movable dielectric plate is connected to the rotating shaft, and as the rotating shaft rotates, the dielectric constant between the capacitor plates undergoes periodic changes, causing periodic changes in capacitance at a rate equal to the rotational speed of the rotating shaft.

5 variable reluctance type: It belongs to the variable reluctance type sensor. The three basic types of variable reluctance sensors, inductive sensors, transformer sensors, and eddy current sensors, can all be made into speed sensors. Inductive speed sensors have a wide range of applications, as they use changes in magnetic flux to generate an induced potential, the magnitude of which depends on the rate of magnetic flux change. This type of sensor can be divided into two types based on their structure: open circuit and closed circuit. The open circuit speed sensor has a relatively simple structure and a small output signal, and is not suitable for use in situations with severe vibration. The inner and outer gears have the same number of teeth. When the rotating shaft is connected to the measured shaft and rotates together, the relative motion of the inner and outer gears causes a change in magnetic resistance, resulting in an alternating induction potential in the coil. By measuring the magnitude of the electric potential, the corresponding speed value can be determined.
