What Are the Classifications of Gear Tooth Speed Sensors?
Gear tooth speed sensors monitor the speed of rotating mechanical components such as gears and racks with high precision, ensuring the stable operation of mechanical equipment. They play a vital role in industrial manufacturing and the automotive industry. The following will detail the classifications of gear tooth speed sensors based on their working principles and application scenarios.
Classification of Gear Speed Sensors Based on Working Principle
Magnetoresistive (MR) Gear Tooth Speed Sensors
Based on the principle of electromagnetic induction, they determine the rotational speed by measuring the change in the magnetic field caused by the rotation of the gear. They feature high measurement accuracy, strong anti-interference capabilities, require no external power supply, and are suitable for operation in harsh environments.
MR gear tooth speed sensors are ideal for applications requiring precise speed and direction sensing, such as automotive, industrial machinery, and robotics.
Hall Effect Gear Tooth Speed Sensor
Utilize a Hall effect element to detect changes in the magnetic field caused by the passage of a gear. Sensitive to magnetic field changes, they provide high-precision speed measurement and are commonly used in automotive ABS systems, crankshaft/camshaft sensing, and general motion detection.
The GS1001-GS1002 Series Hall-effect gear-tooth speed sensors are highly recommended. Made of stainless steel, they are extremely robust and durable, making them ideal for detecting the teeth of iron gears.
Photoelectric Gear Tooth Speed Sensor
These sensors illuminate the gear with a beam and receive the reflected light signal, calculating the rotational speed based on the signal frequency. They are easy to install, require no gear bearings, and are suitable for applications without gear shafts.
