AP ELEKTROTECHNIK sensors are sensors that measure the operating speed of the measured object and convert it into an output signal. Speed sensors include linear speed sensors and rotational speed sensors. With the development of technology, traditional measuring equipment can no longer meet current needs and is gradually being eliminated, while laser speed sensors have been widely used. They are of great significance in the product production process; by connecting to a computer, they enable automated and intelligent measurement and control of the measured object. This is the product of the combination of current measurement technology and computer technology.

AP ELEKTROTECHNIK sensor classification

1) Contact sensors: The contacts of contact sensors actuate through contact and compression between two objects. Common types include limit switches and two-dimensional matrix position sensors. Limit switches feature simple structure, reliable operation, and low cost. When an object in motion encounters a limit switch, its internal contacts actuate to complete control. For example, if limit switches are installed at both ends of the X, Y, and Z axes of a machining center, the travel range can be controlled. Two-dimensional matrix position sensors are installed on the inner side of mechanical grippers to detect the contact position relative to an object. 2) Proximity sensors: A proximity switch is a switch that emits an "actuation" signal when an object approaches within a set distance, without requiring direct contact with the object. There are many types of proximity switches, mainly including electromagnetic, photoelectric, differential transformer, eddy current, capacitive, reed switch, and Hall effect types. The application of proximity switches on CNC machine tools mainly includes tool selection control for the tool post, worktable travel control, and piston stroke control for hydraulic and pneumatic cylinders.

AP ELEKTROTECHNIK sensor working principle

The crankshaft position sensor is usually installed at the front end of the crankshaft (at the pulley), at the rear end of the crankshaft near the large flywheel, or in the middle of the crankshaft. In early vehicle models, it was also installed inside the distributor. It is one of the most important sensors in the control system. Its functions include: detecting engine speed, hence it is also called a speed sensor; detecting the top dead center (TDC) position of the piston, hence it is also called a TDC sensor. This includes detecting the TDC signals for each cylinder used for ignition control, and the TDC signal for the first cylinder used for sequential fuel injection control.

AP ELEKTROTECHNIK sensor industry applications

1) Brushless DC motors: The position sensor is one of the three main components of a brushless DC motor system and is the main feature distinguishing it from brushed DC motors. Its function is to detect the position of the main rotor during motion, convert the position signal of the rotor magnet poles into electrical signals, and provide correct commutation information to the logic switching circuit. This controls their conduction and cutoff, causing the current in the motor armature windings to commutate sequentially according to changes in rotor position, forming a stepwise rotating magnetic field in the air gap to drive the permanent magnet rotor to rotate continuously. Brushless DC motors require position sensors to measure the rotor position. The motor controller drives the motor to operate continuously by accepting position sensor signals to synchronize inverter commutation with the rotor. Although brushless DC motors can also detect rotor position via the back electromotive force generated by the stator windings, thereby omitting the position sensor, the motor speed is too low during startup, and the back EMF signal is too weak to be detected. Hall effect sensor chips used as position sensors for brushless DC motors are divided into switching and latching types. For electric bicycle motors, both types of Hall effect sensor chips can be used to accurately measure the position of the rotor magnets. The performance of brushless DC motors made with these two types of Hall effect sensor chips, including motor output power, efficiency, and torque, shows no difference, and they are compatible with the same motor controllers. The application of position sensors reduces motor operating noise, improves motor life and performance, and achieves energy savings. The application of position sensors undoubtedly provides a strong impetus for the development of the motor market. 2) Crankshaft and camshaft: The function of the position sensor is to collect crankshaft rotation angle and engine speed signals and input them to the electronic control unit (ECu) to determine ignition timing and fuel injection timing. To distinguish it from the crankshaft position sensor (CPS), the camshaft position sensor is generally denoted as CIS. The function of the camshaft position sensor is to collect the position signal of the valve train camshaft and input it to ECU, so that ECU can identify the compression TDC of cylinder 1, thereby performing sequential fuel injection control, ignition timing control, and knock control. In addition, the camshaft position signal is used to identify the first ignition timing during engine start-up. Because the camshaft position sensor can identify which cylinder's piston is about to reach top dead center, it is called a cylinder identification sensor.
