Quick response<\/b>NCTE develops contactless torque sensors with magnetostrictive technology that measure torque, force, shear, and deflection. The magnetized shaft itself acts as a sensor: when it is distorted by the torque, its magnetic field changes and is detected without contact. The standard range includes the 2000, 2300, 3000, 4000, 5000, 7000, and 7300 series. 0.5 Nm to 15,000 Nm<\/b> and accurately from \u2264 \u00b11% to \u2264 \u00b10.1%<\/b>.<\/div>\n

Operating principle<\/h2>\n

The technology is magnetoelastic and measures without contact, even in extreme environmental conditions. The metal shaft is directly magnetized. When the torque distorts the shaft, its magnetic field is distorted accordingly (inverse magnetostrictive principle). These changes are detected and measured without direct physical contact with the shaft, and an output signal is generated showing the torque, rotation, and direction.<\/p>\n

If space is limited, the machine shaft can become part of the sensor, depending on the material (DIN 1.2767, 1.5752, 1.4021, 300M).<\/p>\n

Comparison with strain gauges and optical sensors<\/h2>\n

In NCTE technology, the shaft itself becomes the primary sensor, and a magnetic field is used instead of an additional component on the shaft. The document states that it is maintenance-free and remains stable over time even when not in use, is easy to integrate, and offers weight savings.<\/p>\n
