Bulldozer speed sensors are key devices used for real-time, accurate measurement of bulldozer movement speed, with the core purpose of ensuring construction safety and efficiency. The selection of bulldozer speed sensors requires a comprehensive consideration of accuracy, environmental adaptability, and cost. Radar speedometers are more advantageous in complex working conditions, while wheel speed sensors are suitable for standardized operating scenarios.

Based on technical principles and application scenarios, they are mainly divided into the following two categories:

Strong anti-interference: Unaffected by wheel slippage, tire wear, or sinking, with high measurement accuracy;

Environmental adaptability: Wide operating temperature range (-40°C to +70°C), high protection level, suitable for harsh working conditions;

Real-time performance: Update rate up to 20Hz, supports closed-loop control systems, and can dynamically adjust operating parameters.

Speed is calculated by monitoring wheel rotation speed. Common types include:

Magnetoelectric sensors: Based on the principle of electromagnetic induction, they generate pulse signals when the gear rotates; the frequency is proportional to the rotational speed.

Photoelectric sensors: These generate pulses by blocking or reflecting light signals. They offer high accuracy but are easily affected by contamination.

These sensors are less expensive but are susceptible to interference from tire conditions (such as slippage or deformation), which can lead to measurement errors.
