Abstract

The invention discloses a protective device of a pressure sensor. The protective device comprises a device body, the device body has a hollow structure, the bottoms of outer walls on two sides of the device body are both provided with rotational bolts on which rotational rods are fixed, the other ends of the rotational rods pass through the wall body of the device body, the rotational rods stretch into the mold cavity of the device body, winding reels are fixed at the other ends of the rotational rods, second springs are fixed on two sides of an inner wall at the bottom of the device body, buckles are fixed at the top of the second springs, protective rods are fixed at the top of the buckles, two sides of the protective rods are both rotationally provided with clamping bolts, one sides of the clamping bolts are rotationally provided with limiting rods, fourth springs are sleeved on the limiting rods, and one ends of the fourth springs and the clamping bolts are fixed. The protective device is reasonable in structural design and simple in operation, and can effectively realize automatic popup of the protective rods if the pressure is too great when the pressure sensor is used, thereby playing a protective role, and the protective device is high in sensitivity and good in protection effect.

Description

technical field

[0001] The invention relates to the technical field of pressure sensors, in particular to a protection device for pressure sensors. Background technique

[0002] At present, with the development of Seiko technology, pressure sensors are used in more and more equipment and many mechanical property testing systems. This kind of sensor has the characteristics of simple structure, low cost and mature test system technology, so it can be widely used. Each finished pressure sensor has a standard range. In the process of applying pressure load, if the load exceeds the range of the pressure sensor, it will cause irreversible deformation of the internal elastic body of the pressure sensor, causing the test system to malfunction, thus affecting the performance of the equipment. Accuracy of work and trials. Due to the easy damage of the pressure sensor, the load applied to the pressure sensor must be strictly controlled during the use of the pressure sensor to ensure ...
