Product Details


Mounted to a mixer truck, the Drum Rotation Sensor is designed to measure speed, direction and rotation of the mixer drum. This information can then be translated to show when begin load and begin pour statuses occurred.

Two pcs of magnets with opposite poles need to be fixed on the axis and wheel (the two pcs of magnets are symmetrically distributed, and N pole of one magnet should be fixed facing the sensor and S pole of another magnet should be fixed facing the sensor), and fix the of the arrow on the sensor’s probe test surface facing the rotating arc of the magnet. When the wheel or the axis rotating,


Measures speed, direction and rotation count of the mixer drum

Identifies Begin Load and Begin Pour statuses

Quality control maintains consistent material and satisfied customers

Technical Parameters

a) Power supply voltage: direct current

b) Output method: open-collector output

c) Probe detection distance: recommended

d) Working environment: temperature -2

e) Signal status: The blue wire output indicates direction, when at original status or positive rotating, it outputs low electrical level, green light is on, and the positive rotating direction is the same with the arrow direction. When negative rotating, it outputs high electrical level, red light is on, and the negative rotating direction is the opposite to the arrow direction.

The white wire output indicates rotating speed, and it is the square wave signal. 

f) Protection level: IP65 

g) Anti-vibration ability: 5G under normal situation
