Ultra-high precision displacement (float level) sensor-LF700

Product introduction

The LF700 series displacement sensor calculates the exact location of the intersecting point of the magnetic field by using the detection time of the strain pulse signal generated when two different magnetic fields intersect. From sensors electronic storehouse of electronic components, a magnetic field generated by the pulse, the pulse of the magnetic field generated along the sensing device inside the rod with high magnetostrictive material waveguide made of silk at the speed of light from end to end, electronic storehouse when and activities of the permanent magnetic field (the permanent magnets general installation on the need to detect position of the moving plate) intersect, due to the magnetostriction phenomenon, A mechanical strain pulse is generated at the intersecting point of the waveguide wire, which is transmitted back to the end of the electron bin at the speed of sound. The strain pulse is detected by the detection circuit in the electron bin. Therefore, the time between transmitting an active pulse wave and receiving a strain pulse wave is the transmission time of sound velocity in the waveguide wire (the operation time of the active wave has been ignored here, and the actual effect is only 0.0001%). Given the speed of sound (the fixed quantity is 3000m/s) and the transmission time, the distance is certainly determined. The above measurements are reconfirmed when the permanent magnet moves to a new position. Therefore, the magnetostrictive displacement sensor has the advantages of high precision, high response, low hysteresis, high reliability, non-contact, long life, high stability, easy installation and so on, without re-calibration, without regular maintenance, so it is widely used in the field of accurate measurement.
