Overview:The magnetoelectric speed sensor can convert the angular displacement into an electrical signal for the counter to count, as long as it is non-contact, it can measure various magnetically conductive materials such as gears,The rotational speed and linear speed of the impeller, the disc with holes (or slots, screws).The sensor has the advantages of small size, strong and reliable, long life, no need for power supply and lubricating oil, etc. It can be used with general secondary instruments.2. Technical parameters1. Output waveform: approximate sine wave2. Output signal amplitude:The gap between the sensor core and the tooth tip of the measured gear is = 0.5~ 1.2mm (0.5mm distance is the best)Measured gear module m= 2~6The magnitude of the signal amplitude is proportional to the rotational speed and inversely proportional to the size of the gap between the iron core and the tooth.3. Measuring range: 100~ 40000Hz4. Use time: continuous use5. Working environment: temperature: -30~+125C6. Output form: two-wire output (red signal output, black connected to the negative pole of the power supply)7. Dimensions: outer diameter M16x1.5; M18x 1.5 overall length 80mm3. Outline drawing: L= 80+3mmN L1= 60+1mm, M= 21.8+0.3MM4. Precautions for use1. The thread of the sensor shell should not be damaged during installation, the hexagonal nut should rotate freely, and there should be no looseness after the hexagonal nut is tightened.2. It is advisable to install the gear under test without contacting the sensor. And hope to reduce the gap as much as possible to improve the output signal amplitude.
