Sensor have signal acquisition part and signal processing part, collect the internal signal of torque size, sent the electrical signals to the electronic module, and finally output a analog voltage signal similar to the hand signal. Then send the output analog voltage signals to the controller, then control the motor, And torque sensor control the vehicle movement state.

Advantages of axial type/bottom bracket torque sensor:

National patent product, with a standard length of bottom bracket (68 mm)

Simple assembly, good stealthiness , suitable for single speed gear disk and variable speed gear disk.

Linear Zero Start : it can start instantly according to the size of the one pedaled on the starting force,and according to the size of the human, Strength size is linear output ratio.

Good follow-up:disk can collect the signal nearly 100 times rotation a circle, the data quantity is big. and the output response in a timely manner, so the signals of torque are smooth, wide linear range and the power off timely when it stop pedaled, total time are completed in 200 ms.

⑤ Reliability: the structure is simple, less number of parts. Anti-interference ability:can work in turbid water.

Parameter adjustment function:customers can adjust the parameter to meet the requirements of own by setting tool, including:

(1) Matching different machine control system.

(2) Conversion between JIS and EN standards.

(3) The size of the output current, the proportion of smoothness and pedaled wave.

(4) The strength size of the instrument’s three mode(Low,Med, Higher).

(5) The strength of the zero start.

(6) Delay time.

Both domestic and international are leading levels. Compared with any other products at home and abroad, it has more open interface, more generic, more style, higher performance and competitive of price.
