Problems solved by technology

[0005] This will bring the following technical disadvantages: the measurement frequency is uneven in the full range; the measurement frequency drops when the cursor is far away from the sensor head, which affects the accurate measurement of the real-time position of the cursor, especially when the cursor is running at high speed, the measurement frequency is difficult to keep up with upper movement speed

Abstract

The invention relates to a magnetostriction sensor used for displacement measurement and liquid level measurement. A measurement module of the sensor comprises n measurement units, wherein n is a natural number larger than or equal to 2. The measurement units adopt arbitration mechanisms such as FIFO, token circulation and polling, one idle measurement unit obtains the measurement right each time, another idle measurement unit starts measurement of next time before echoes corresponding to the idle measurement unit return, and the activated measurement units successively obtain echo signals according to the starting sequence. The highest measuring frequency of the magnetostriction sensor is k times that of an original design product, wherein k is a natural number larger than 1.

Description

technical field [0001] The invention relates to a magnetostrictive sensor, which can be used for displacement measurement and liquid level measurement, and in particular to a magnetostrictive sensor whose measurement frequency is n times that of traditional products, where n is a natural number greater than or equal to 1. [0002] Background technique [0003] Magnetostrictive sensor, English name Magnetostrictive Sensor. It is a sensor based on the magnetostrictive Wiedemann effect. During the measurement, the excitation module in the electronic cabin applies an inquiry pulse at both ends of the magnetostrictive waveguide wire of the sensitive detection element, and the pulse forms a circumferential ampere ring magnetic field around the waveguide wire at the speed of light, and the bias of the ring magnetic field and the vernier magnetic ring When the permanent magnetic field is coupled, a Weidmann effect torsional stress wave will be formed on the surface of the ...
