SEMPU new generation of Bottom Bracket Torque Sensor
Sempu is a high-tech enterprise committed to providing intelligent drive system solutions and key componens for electric bikes.
The company was founded in 2011 by a group of industry with more than 15 years experience in developing and manufacturing electric bike drive systems.
The range of products includes double-sided torque sensors and controller integrated motors. With torque sensor as the core technology, the company will be adding new components to the future product roadmap.
Sensor signal
The Bottom Bracket Torque Sensor outputs a voltage signal. The signal and the pedal force is linear proportional. Pedal force increases every 10kg, 0.15V voltage changed. The detectable maximum pedal force is 80kg. The input signals into sine wave with the crank angle. The outputs in 0° and 180° are zero. Maximum output is in 90° and 270°.
Each rotation of 12°, the Bottom Bracket Torque Sensor outputs a speed signal. The shaft rotates a circle with 32 speed signal output.
Product advantages
The advantages include faster start and quicker response. No more temperature drift issue with high reliability in low temperature. Compatibility with standard bottom brackets, more easy to install and flexible lenth options, custom dimension and compatible with mid-drive motor.

About ExtraEnergy e.V.
ExtraEnergy e.V. has carried out independent e-bike and pedelec tests since 1992. Since then the organisation has established itself as the most influential information, user protection and promotional organisation for light electric vehicles (LEVs) worldwide. The ExtraEnergy Test verdict is a recognised stamp which marks out good products and offers customers reliable guidance for their purchasing. The flip side of independent buying advice is straight-talking warnings about substandard products.
The founders realised from the start that these vehicles need to be experienced first-hand. Since 1997 the Test IT Track has been on the road, and today has three units for the Test IT Show. ExtraEnergy is also rooted at its test facility in Tanna, where 22 years of test reports and LEV history are on display at the LEV Museum.
Other services on offer include presentations and exhibitions at trade and public shows, plus information distribution with the assistance of correspondents worldwide.
Alongside our physical presence, www.extraenergy.org provides a treasure-house of information online. With support from the European Union and the IEA (International Energy Agency), in 2012 the GoPedelec! Handbook was published in German, English, Dutch, Hungarian, Czech, Italian, Spanish and Chinese, including much new information and best practice studies for electric-assist two-wheelers.
As founding members of the EnergyBus and BATSO (Battery Safety Organization) associations, ExtraEnergy is also active on both the ISO (International Standards Organisation) Standards Committee, with a focus on mechanical standardisation, and on the IEC (International Electrotechnical Commission), and so helps set safety and communication standards for LEVs worldwide.
