Problems solved by technology

Weights are generally the benchmark for pressure gauge testing and calibration. It is a common practice for pressure gauge testing to form a specific weight through a specific combination of weights to exert pressure on the pressure gauge. However, at present, the work of adding weights is generally done manually. Repetitive labor, dry work, manual overweighting is difficult to maintain stable pressure, and the pressure fluctuates greatly. The system cannot perform real-time measurement and automatic compensation, which brings errors and other problems to the verification results, and manual operation is easily affected by factors such as ambient temperature, humidity, and atmospheric pressure. influences

Abstract

The invention discloses a sequential weight adding device, which comprises a supporting plate (3). The bottom of the supporting plate is provided with a lifting mechanism; discal weights (6) are arranged in a stacking mode on the supporting plate via supporting units; the edge of the weight (6) of each layer forms a flange and the weight is lapped in a reverse hanging mode on the supporting part of the supporting unit; interference does not happen in the case of loading due to the arrangement relationship between two adjacent layers; and in addition, a weight tray (8) with additionally provided a weighing or pressure detection mechanism is provided between below the bottom weight and the supporting plate (3). The sequential weight adding device is used in a pressure detection or weighing system, automatic and sequential weight adding can be realized for weight adding operation, the operation is convenient, and weight adding is accurate.

Description

technical field [0001] The invention relates to an automatic weight adding device, in particular to an automatic weight adding device applied in the field of pressure detection, that is, a sequential automatic weight adding device. Background technique [0002] In the field of physical quantity detection, it is often required that the detection system provide a specific force. For example, in the field of pressure detection, various forms of pressure gauges, pressure sensors, and pressure transmitters are commonly used instruments for pressure detection. industrial processes and research fields. The performance of the pressure gauge is directly related to the quality of the test results. In order to ensure the detection accuracy of the instrument, the pressure gauge must be calibrated regularly. Currently, it is common practice for businesses to perform periodic checks and calibrations on all pressure gauges. This requires that the pressure gauge detection and calibration...
