Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0019] Such as Figures 1 to 4 As shown, a pressure sensor resistance testing tool includes a base plate 1 and a sensor fixture 16. An electric heating table 2 is installed in the middle area of the top of the base plate 1. The electric heating table 2 is used to provide high temperature for the pressure sensor placed above it. To detect the environment, side plates 6 perpendicular to the base plate 1 are installed on the left and right sides of the electric heating table 2 on the bottom plate 1, and the two side plates 6 are parallel to each other and a mounting plate 4 is installed in the middle rotation, and each side plate 6 The front portion is provided with a round hole 7, two round holes 7 are coaxial, and a bearing 8 is installed in each round hole 7, and the front end of the mounting plate 4 is provided with a rotating sha...

The invention relates to a gauge for detecting the resistance of a pressure sensor, comprising a bottom plate and a sensor clamp. The bottom plate is equipped with an electric heating table on the top. Side plates perpendicular to the bottom plate are mounted on the left and right sides of the electric heating table, respectively. The two side plates are parallel to each other and are equipped with a mounting plate rotatably in the middle. A detecting head is mounted at the bottom end of the mounting plate. A cover plate is mounted at the top ends of the two side plates. A resistance detectoris mounted on the cover plate. The resistance detector and the detecting head are connected through a flat cable. The bottom end of the cover plate and the top end of the mounting plate are connectedby a spring. The rear side of the electric heating table is connected with the rear side of the mounting plate through a thin metal piece. A push plate is arranged at the front end of the sensor clamp. The sensor clamp is provided with a clamping groove therein for mounting a sensor. The beneficial effects of the gauge in the invention are that the pressure sensor is mounted in the clamping grooveof the sensor clamp and the pressure sensor is placed on the electric heating table by the sensor clamp to perform a resistance test, thereby preventing an operator from being burnt.
Description
technical field [0001] The invention relates to the technical field of pressure sensor manufacturing, in particular to a test tool for resistance detection of a pressure sensor. Background technique [0002] A pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. A pressure sensor usually consists of a pressure sensitive element and a signal processing unit. [0003] After the pressure sensor is processed, it is necessary to perform resistance detection on the pressure sensor at room temperature and high temperature, so as to calculate the temperature drift of the pressure sensor and judge whether the temperature drift of the sensor meets the standard. When detecting the resistance of the pressure sensor at high temperature, if the operator directly places the pressure sensor on the heating table, it is easy to burn the operator's hand, resulting in a safety ac...
