D Group 28 Design and Function Sensors Clutch Position Sensor The Clutch Position Sensor is located on the side of the clutch cylinder assembly (inside bell housing). Main Shaft Speed Sensor(s) The speed sensors are located on the control housing and measure the speed of the main shaft and the speed of the countershaft. The main shaft speed sensor is a electronic sensor with a hall element. Using a hall element makes it possible to measure the rotation speed and rotation direction of the shaft. The countershaft speed sensor is an inductive sensor. Knowing the speed of the countershaft makes it possible to calculate the precise speed of every gear in the transmission.
The speed sensor(s) are located in the transmission on the lower portion of the control housing. Output Shaft Speed Sensor The Output Shaft Speed Sensor is located on the side of the rear transmission housing. Range Cylinder Position Sensor There are four position sensors in the transmission control housing. These sensors measure the position of the specific air cylinder within the control housing. The sensors are inductive and the inductive characteristics change depending on the position of the metal pin that follows the movements of the air cylinders. The Range Cylinder Position Sensor is located in the transmission on the lower portion of the control housing.
Split Cylinder Position Sensor The Split Cylinder Position Sensor is located in the transmission on the lower portion of the control housing. 1st/Reverse Cylinder Position Sensor The 1st/Reverse Cylinder Position Sensor is located in the transmission on the lower portion of the control housing. 2nd/3rd Gear Cylinder Position Sensor The 2nd/3rd Gear Cylinder Position Sensor is located in the transmission on the lower portion of the control housing. 9
