GTS gear speed sensor:
An advanced speed sensor for non-contact detection of rotating body speed. The measuring range is from 1 rpm to 20,000 rpm. The output square wave signal can be directly
interfaced with TTL, CMOS and other circuits to form a speed measurement/control system.
GTS The product adopts the waterproof structure of round pipe, has the advantages of waterproof, dustproof and oil proof, and can work reliably in harsh environment, especially suitable for industrial control and military projects.
First, the basic technical performance
1, rated detection distance: 2mm
2, detection frequency response: 1Hz ~ 10KHz
3, speed range: 1 ~ 20000rpm (matching with the appropriate gear)
4, working voltage polarity protection and output short circuit protection
5, Working temperature -20~75°C
2. Electrical performance
1. Working voltage: 12~30VDC
2. Static power consumption current: ≤30mA
3. Maximum output current: 50mA
4. Output low level voltage: ≤0.5VDC
5. Rising edge Time: ≤ 2us
6. Falling edge time: ≤ 2us
7. Output mode: NPN open collector output (OC), square wave, duty cycle 50±20%
3. Detection gear
1, modulus: m≥1
2. Gear thickness: ≥4mm
3. Tooth shape: involute or trapezoidal straight tooth
4, gear material: magnetically conductive material (such as 45# steel)
IV. Instructions for use
1. Dimensions of the sensor are shown in Figure 1. The sensor is installed with the sensor. The nut is fixed to the mounting hole and the fixing device is recommended
Sensors using non-magnetic materials (copper, stainless steel, etc.) should be mounted on the tooth surface. The spacing between the tooth surface and the front end of the sensor should not be greater than the rated detection distance.
2, the detection gear may be a conventional machine or a special gear of the work gear, but it shall comply with three items, shall make
possible to use a smaller detection distance, the gear should be used as a large high permeability material Modulus.
3. The actual speed range varies according to the number of teeth of the gear N. It can be calculated by the following formula: the
lower limit of the speed range: Vmin= (rpm); the upper limit of the speed range: Vmax= (rpm)
4. See Figure 2 for the wiring diagram. A sensor housing connected to the shield layer and the shield line, the user at the receiving end should be connected to system ground shield
5, to enhance the ability of anti-jamming signal, the sensor can be a current output, and at the receiving end compartment optocoupler from
