1. Product name: Axial Type/Bottom Bracket Torque Sensor-- meet the Eu's EN15194 standards. 
2. Model: The JCP - C 
3. Assembly requirements: 
(1) Bottom Bracket Torque Sensor adopts standard length (68 mm), whether it has thread in bottom bracket shells. 
(2)bottom bracket torque sensor(JCP-C) and tooth disc torque sensor (JCP-2) all adopts modular design, module can be universal. The sensor wire adopts 6 core waterproof plug-ins (about 10 mm in diameter), the right end the direct line and do not need to punch. There is no requirements about circumferential position. 
4. Assembly method and assembly diagram: 
Bottom Bracket Torque Sensor directly arranged into the bottom bracket, be sure to install the sensor in (to the right tooth part into BB). At the same time, adjust the outlet position, using a crescent wrench fixed right bowl and then locked left nut tightly. 
The assembly diagram below: 
5. Connection: 
The bottom bracket torque sensor----module---controller---motor----driven vehicle 
Instrument 
This set of sensors as well as connection with JCP-2 (see the line chart) 
6. Specifications: 
(1). The CL: Standard size 50 mm. (Special sizes can be customized) 
Single: 36t, 38t, 40t, 42t, 44t 
(2). The Chain wheel Double: 38-48 t 
Three: 24-34-42t, 28-38- 48t, 
(3). The Crank Length: 152MM, 165MM, 170MM
7. Versatility of Bottom Bracket Torque Sensor 
The output signal interface definition of Bottom bracket torque sensor and tooth disc torque sensor are same, but there is little different of setting parameter due to the different structures. Compared to other tooth disc torque sensors, BB torque sensor need offer additional CL parameters (Chain line). 
8. Advantages of axial type/bottom bracket torque sensor: 
(1)National patent product, with a standard length of bottom bracket (68 mm) 
(2)Simple assembly, good stealthiness, suitable for single speed gear disk and variable speed gear disk. 
(3) 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. 
(4)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. 
(6) Parameter adjustment function: Customers can use Setting tool to adjust the parameter to meet different requirements by oneself, including: 
(a)Matching different machine control system. 
(b)Conversion between JIS and EN15194 standards. 
(c)The size of the output current, the proportion of smoothness and pedaled wave. 
(d) The strength size of the instrument's three mode(Low, Med, Higher). 
(e)The strength of the zero start. 
(f) Delay time. 
(7)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.
