EMS Educational Material_001 6. The MagAlpha sensor is able to generate both the UVW commutation signals and the position information needed for motor control systems, either in the form of a direct digital angle read over the SPI interface or an ABZ incremental en- Position Sensor Installation Important Installation Notes 1. A sensor’s Accuracy is a measure of its output‘s veracity A sensor’s Resolution is a measure of the smallest increment or decrement in position that it can measure A sensor’s Precision is its degree of Repeatability. Normally three tracks are used to monitor the position 7- Optical position encoders (2) Outer track Middle track Inner track The head includes an electronics module, which reports the position information to a controller (or other receiving device) in the appropriate analog or digital format. plications. Distance between sensors should be 1.50 inches or more. Using position sensors for end-of-travel protection reduces effective 2. sensor. Position sensors measure either absolute or incremental displacement, and are made with a variety of different materials. 03_Throttle Position Sensor 12/19 . An internal rotary sensor mated to the spool tracks the position of the … tape measure, the body of the sensor is bolted to a stationary, fixed position, at one end of the stroke while the free end of the steel cable is then attached to the moving object being tracked. in the position of the sensing shaft creates stress in the stress-sensitive core. 3. General . In position sensors which use hall efffect, the moving part is connected to a magnet.Thus, the sensor consists of a Hall element and a magnet housed within the sensor shaft. Magnetic position and speed sensors are rugged and durable. Also, when the sensor’s power fails, some retain the measured position data, and other types lose the information. Figure 1:Magnetostrictive Linear-Position sensor with sensing rod and position magnet. Position sensors may be mounted along either side of a cylinder. If sensors are located closer than 1.50 inches apart, they may trigger at the same time. Motion Axis Sensing Rod The inductance is a function of the shaft's position. A sensor’s Linearity is the difference between a sensor’s output to the actual position being position, and speed control. The permeability of the core material alters with stress, effecting the inductance of the winding wound around the core. When the disc is rotated, a pulsed output is produced by the sensor with the number of pulses being proportional to the angle through which the disc rotates. With the movement of the body or its part the magnet also moves and therefore, the magnetic field … For example, RTY050LVEAA de˜nes an RTY Series Hall-Effect Rotary Position Sensor, 50° (±25°) sensing range angle, 5 Vdc supply voltage, European pinout style, 4.5 Vdc (left), 0.5 Vdc (right) output type, shaft without lever actuation type One common device is a resistive position sensor … and the position magnet is attached to the member that will be moving. Current throttle position is checked by TPS sensor.
