Product Description
Magnetic Speed Sensor MEVS-08
Description
MEVS series magnetic speed sensor, do not require an external voltage source for operation. A permanent magnet in the sensor establishes a fixed magnetic field. The approach and passing of a ferrous metal target near the sensor's pole piece changes the flux lines of the magnetic field, dynamically changing its strength. This change in magnetic field strength induces a current into a coil winding which is attached to the output terminals.
The output signal is an ac voltage that varies in amplitude and wave frequency as the speed of the monitored device changes, and is usually expressed in peak to peak voltage (Vpp). The higher the speed, the higher the output voltage. The frequency is proportional to the speed.
Features
Self-powered operation
Simpe installation
Can detect speed 30rpm minimum
High output signal, good anti-interference
Can be used in harsh environment: smoke, oil and water vapor, etc.
Applications
Gear speed measurement
Engine RPM (revolutions per minute) measurement on aircraft, automobiles, boats, buses, trucks and rail vehicles
Motor RPM measurement on drills, grinders, lathes and automatic screw machines
Process speed measurement on food, textile, paper, woodworking, printing, tobacco and pharmaceutical industry machinery
Flow measurement on turbine meters
Motor speed measurement of electrical equipment
Wheel slip measurement on autos and locomotives
Speed measurement of pumps, blowers, mixers, exhaust and ventilating fans
