Technical Field
[0001] This utility model relates to the field of pressure sensor technology, specifically a pressure sensor temperature and pressure testing device. Background Technology
[0002] A pressure sensor is a device that senses pressure signals and converts them into usable electrical output signals according to a certain rule. Pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. Based on different types of pressure being measured, pressure sensors can be classified into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. Pressure sensors are one of the most commonly used sensors in industrial practice, widely applied in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemicals, oil wells, power, shipbuilding, machine tools, pipelines, and many other industries.
[0003] Traditionally, pressure sensors are tested by directly squeezing them. However, since pressure sensors are also affected by external temperature, a single squeezing test cannot simulate real-world usage scenarios, making the test results unrepresentative and affecting the overall test effectiveness. Utility Model Content
[0004] The purpose of this invention is to provide a pressure sensor temperature and pressure testing device to solve the problem mentioned in the background art that, in the traditional way of testing current pressure sensors, the detection operation is directly performed by compression. Since the pressure sensor is also affected by the external temperature, the single compression test cannot simulate the real use scenario, making the test results unrepresentative and affecting the test effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A pressure sensor temperature and pressure testing device includes a supporting base plate, with a base pad symmetrically abutting the bottom surface of the supporting base plate. A supporting top plate is vertically fixed to the top surface of the supporting base plate, and a control panel is fixedly mounted on one side of the supporting top plate. A placement groove is horizontally formed on the top surface of the supporting base plate, and a sealing cover is horizontally engaged with the inner side of the placement groove. A telescopic upright is vertically fixed to the top surface of the supporting base plate, and a fixed top rod is horizontally fixed to one side of the telescopic upright. A supporting sleeve rod is vertically fixed to the bottom surface of the telescopic upright. The bottom surface of the supporting base plate is symmetrically formed... The bottom pad has a bottom screw hole, and a connecting screw is fixedly inserted into the top surface of the bottom pad. A sealing groove is horizontally opened on the inner side of the top groove. An installation slot is provided on the inner bottom surface of the top groove. A heating inner layer is fixedly snapped into the inner wall of the top groove. A heating tube is embedded in the inner wall of the heating inner layer. An inner cylinder is vertically fixedly connected to the inner side of the telescopic upright. An extension bottom rod is vertically inserted into the bottom end of the support sleeve. A compression cylinder is vertically fixedly connected to the inner side of the support sleeve. A compression bottom block is fixedly provided at the bottom end of the extension bottom rod. A sealing frame is fixedly provided on the bottom surface of the sealing cover.
[0007] In a preferred embodiment of this utility model, the number of bottom pads is four, and the top surfaces of the four bottom pads are all connected and aligned with the bottom opening of the bottom screw hole. The supporting top plate is vertically fixed at one corner of the top surface of the supporting bottom plate.
[0008] In a preferred embodiment of this utility model: the placement top groove is horizontally opened at the center of the top surface of the support base plate, the sealing cover is horizontally fixedly connected to the bottom of the outer side of the support sleeve rod, and the bottom of the telescopic upright is fixedly connected to one end of the center line of the top surface of the support base plate.
[0009] In a preferred embodiment of this utility model: one end of the fixed top rod is fixedly connected to the top side of the telescopic pole, the top end of the support sleeve rod is fixedly connected to the bottom surface of the fixed top rod at the end away from the telescopic pole, the bottom screw holes are symmetrically opened on the bottom surface of the support base plate near the four corners, and the top end of the connecting screw is fixedly connected to the inner side of the bottom screw hole.
[0010] In a preferred embodiment of this utility model: the mounting slot and the heating tube are electrically connected to the internal main board of the control panel, the top end of the extension rod is inserted into the bottom channel of the support sleeve rod, and the extension rod and the support sleeve rod are configured as telescopic rods.
[0011] In a preferred embodiment of this utility model, the output end of the extrusion cylinder is extended and fixedly connected to the top of the extension base rod, and the bottom surface of the sealing frame is snapped onto the inner side of the sealing channel.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention involves horizontally placing a pressure sensor inside a mounting slot, electrically connecting its bottom to the mounting slot, and then horizontally positioning the pressure sensor on the bottom surface of the mounting slot. After configuring the control panel, the output end of the internal cylinder extends, causing the telescopic upright to move the top fixed rod downwards. This allows the bottom support sleeve to snap into the top opening of the mounting slot, and the bottom sealing cover to snap into the inner side of the mounting slot. The sealing frame then engages with the sealing channel to create a seal. After the heating element is heated to a specified temperature, the interior of the mounting slot is heated to the specified temperature. Simultaneously, the output end of the compression cylinder extends downwards, inserting the bottom end of the extension rod into the mounting slot. The compression block at the bottom presses against the top surface of the pressure sensor, creating a compression detection operation. The control panel displays and records the detected data. The integrated structure makes control and use more convenient and efficient, and the combination of pressure and temperature detection structures allows for more accurate and efficient pressure sensor detection.
