Working principle
Core Structural Foundation
The differential sensing element at the sensor's front end is the core of its operation. It consists of a small permanent magnet and two series-connected magnetically sensitive semiconductor resistors. These two resistors form a Wheatstone bridge, which is connected to a fast push-pull DC amplifier with output short-circuit protection, providing structural support for subsequent signal conversion.
Magnetic Field Interference and Bridge Imbalance
When a soft magnet or steel trigger approaches the sensor probe perpendicularly, it interferes with the probe's internal magnetic field. This magnetic field disturbance disrupts the balance of the Wheatstone bridge, causing the output voltage to rise.
Pulse Signal Generation
This high-level state is maintained until the trigger touches the probe. At this point, the magnetic field reverses, causing a reverse imbalance in the bridge, which in turn changes the output voltage. The resulting output signal is a pulse signal with extremely steep edges. Even at a low trigger frequency, this pulse signal can be transmitted to subsequent electronic equipment via capacitive coupling, enabling the measurement of parameters such as rotational speed.
