Brass Magnetic Pick Up For Sale
Specification of Speed Seneor The MEVS series gear tooth speed sensor is industrial-grade gear tooth speed senor, also named magnetic pick-up or passive speed sensor. As a ferrous object approaches the tip of the pole piece, the magnetic field increases and decreases as the object move away from the pole piece, the snap or the rapid change in the magnetic field induces, an AC voltage signal in the coil, with an ideal target and matching sensor, the induced voltage is in the shape of a sine wave.The generated frequency signal is directly proportional to the number of ferrous objects passing the pole pieces per unit time, the amplitude of the voltage output is proportional to the speed of the ferrous objects passing the pole piece. MEVS Series gear tooth speed Sensor provides a user-friendly solution, senses rotating ferrous gear tooth. The sensor output waveforms with various targets are difference, the commonly used gear terminology, diametric pitch equal no. Of tooth add 2, besides dia. of gear (inch).The performance of a sensor can be easily defined, when using a gear for a target. We recommendation a standard gear target for evaluate the performance of a sensor, that may differs from most sensor manufacturers and test parameter, It is notice for estimated performance.This sensor's ability to provide tight duty cycle at high speeds and over a wide temperature range makes it for transmission and industrial speed application.Features:1.Sensor with adjustable stainless steel or Brass housing.2.Small compact size, low price.3.Simple mounting3/8" UNF -24 threads and 2 jam nuts to secure the sensor.4.Large operating air gaps.5.Industrial-grade sensor,bad environment compatible,such as dirt and oil environment. Characteristics6.Inductance 190mH7.DC resistance 1000 O8.Output Voltage: 13.4V (P-P)9.Operating temperature: -40℃～125℃10.Operating Air Grip: 0.5～2.5mmNote:In order to assist you selecting your sensor, yuanben co., ltd. Has developed an output & speed curve of GMESS series, by looking at the application extremes of highest speed lowest gap and lowest speed / highest gap. The full variation of sensor output can easily be determined.Gear InformationThe MEVS series Sensor can be used in conjunction with gears of various Shapes and sizes example as follows.Diameter is 120mm, thick ness is 6mm, tooth width is 3mm, valley width is 3mm, and valley depth is 3mm. The material is low carbon steel.Cable informationA shielded Cable is recommended, for particularly noisy environment or the length of cable is over 1500mm. MountingThe speed sensor must be installed so that the mounting axis is perpendicular to the direction of rotation. The flat side of the sensor housing must be parallel to the direction of the gear rotation.Appliance The MEVS sensor directly sense rotating ferrous gear type gears such as web speed gears, power transmission gears, conveyor speed and other similar gear-based shaft encoder.
