MTS displacement sensorIt is a high-precision sensor used to measure linear or rotational displacement in mechanical systems, widely used in various fields such as industrial automation, aerospace, and automotive manufacturing. Based on the principle of magnetostriction, its core components include a ferromagnetic waveguide and a movable permanent magnet. When a current pulse passes through a waveguide, a longitudinal magnetic field is generated in the waveguide. When it intersects with the magnetic field of a permanent magnet, the waveguide will exhibit magnetostriction, generating a strain pulse signal. This return signal travels back to the sensor electronic head at ultrasonic speed. By measuring the round-trip time of the signal, the sensor circuit can accurately calculate the position of the permanent magnet and provide an absolute position reading. This non-contact measurement method eliminates mechanical wear and ensures the repeatability and durability of the measurement.
MTS displacement sensorThe main characteristics are:
1. Non contact measurement, no mechanical wear
Core advantage: There is no physical contact between the "induction ring" (magnet) of the sensor and the internal "waveguide".
Result: The mechanical friction and wear of traditional potentiometer or sliding contact sensors have been eliminated, achieving theoretically infinite service life, especially suitable for situations that require long-term continuous operation.
2. High precision and high repeatability
High precision: The typical linearity can reach ± 0.01% FS (full scale), and some models even have higher accuracy.
Repetitive polarity j: can reach ± 0.001% FS or micrometer level, ensuring highly consistent measurement results each time.
High resolution: can reach sub micron level (<1 μ m), capable of detecting extremely small positional changes.
3. High reliability and long lifespan
Durable and sturdy: Made of stainless steel waveguide and sturdy casing, it can withstand harsh industrial environments such as vibration, impact, and oil pollution.
Long lifespan: Due to non-contact measurement, wear and tear are avoided, and the mean time between failures (MTBF) of MTS sensors is extremely long, resulting in low maintenance costs.
High IP protection level: usually up to IP67 (dustproof, anti short-term immersion), some models can reach IP69K (resistant to high-pressure and high-temperature water flushing), suitable for humid and dusty environments.
4. Multiple output signals and interfaces
Analog output: Standard 0-10V, ± 10V, 4-20mA, 0-20mA, etc., can be directly connected to PLC and controller.
Digital output: Supports mainstream industrial bus protocols such as SSI, CANopen, Profibus DP, DeviceNet, IO Link, etc., making it easy to integrate into modern automation systems.
Flexibility: Users can choose the appropriate output method according to system requirements.
5. Flexible installation and strong adaptability
Multiple installation methods:
External Mount: Installed outside the device, easy to maintain and replace.
Flush Mount/Hydraulic Cylinder Integrated: directly installed inside the hydraulic cylinder piston rod, saving space, and is a standard configuration for hydraulic servo control.
Customization of measuring rods: Different diameters, lengths, and materials of measuring rods can be provided to meet different application needs.
6. Excellent temperature stability and anti-interference ability
Temperature compensation: Equipped with a built-in temperature compensation circuit, it can maintain measurement accuracy over a wide range of ambient temperatures (such as -40 ° C to+85 ° C or higher).
Anti electromagnetic interference (EMI): Designed with excellent resistance to electromagnetic interference, stable signal, suitable for strong electromagnetic environments such as frequency converters and motors.
7. Fast response speed
High measurement frequency, fast response time (up to microsecond level), capable of real-time tracking of position changes of high-speed moving parts, suitable for closed-loop control systems with high dynamic performance requirements.
8. Absolute position measurement
Immediately output the current position value after power on, without the need for "zero return" or "parameter search" operations. Even if the power is turned off and restarted, the position can be immediately known (for models that support absolute value output).
