TURCK inductance linear displacement sensor NI5 - G12 - AP6X 7M series

 The linear displacement sensor developed on the basis of the working principle of the inductor coil is unique, and the technology adopted by Turk Company has reached a position in the range. Many excellent characteristics of the standard measurement system are integrated and developed step by step systematically. Position detection is no longer done by magnetic sliders but by inductive oscillating circuits. Therefore, the sensor is completely shielded from the interference of magnetic field, such as the strong magnetic field interference generated by a large motor, and has good EMC characteristics. TURCK inductance linear displacement sensor. The measurement principle of the new linear displacement sensor is based on the RLC coupling circuit, which is an innovation technology of inductance principle. Unlike the principle of potentiometer or magnetostrictive sensors, this method of measurement has considerable advantages. The sensor integrates a system of transmitter and receiver coils, which are precisely printed on the circuit board in the form of printed coils. The transmitting signal coil is activated by a high-frequency AC magnetic field and interacts with the position block (resonator) to generate an induction circuit of RLC. Thus, the resonator is inductively coupled to the receiving coil. At the location of the receiving coil, the voltage change is caused by the induction of the resonator with the coil. These voltages are the measurement signals of the sensor. To make the measurement more flexible and fast, the sensor includes a system of rough and precise measuring coils. The former is responsible for roughly locating the position of the resonator, while the latter is responsible for precise positioning. The two-pronged approach ensures its accurate measurement. The new detection principle not only ensures the accuracy of the sensor, but also enables the sensor to work in a non-contact way. Within the allowable range, even if the position block is offset or jitter, there will be no deviation to the sensor output.
