[0001] The utility model relates to sensor technical field more specifically, the utility model relates to a kind of high-temperature high-precision displacement sensor device. BACKGROUND

[0002] Displacement sensor, also known as linear sensor, is a kind of metal induction linear device, which mainly converts various measured physical quantities (such as length, angle, shape, compression, elongation, etc.) into electric quantity (usually voltage or current) for output, so as to facilitate transmission, processing, storage, display, recording and control.

[0003] The traditional displacement sensor has the following disadvantages: when working in a high-temperature environment, the electronic components and mechanical structures inside the sensor are prone to failure due to extreme temperature, resulting in great instability during use. At the same time, high temperature can accelerate the aging process of materials, greatly reducing the precision and reliability of the sensor. In addition, high temperature may cause short circuit of the circuit or burning of the components, thereby directly damaging the sensor. This not only affects the normal operation of the equipment, but also may cause safety hazards; generally, the displacement sensor needs to be placed in a heat-insulating shell, but when the shell space is larger than the displacement sensor, the displacement sensor may move in the shell space, thereby affecting the accuracy of its measurement, therefore, it needs to be improved.
