Abstract

The invention belongs to the technical field of pressure transmitters, and particularly relates to a high-precision pressure transmitter aging test system test device, which comprises a basic test system, and the basic test system comprises 1-10 basic test boards, a power supply / control box, a computer and a display system. Each basic test board can comprise 1-24 measurement modules, the measurement modules adopt a modular design mode, each measurement module corresponds to one pressure transmitter, two extended junction box wiring terminals are arranged at the end part of each basic test board, and the basic test boards are connected through the extended junction box wiring terminals. A data acquisition component is arranged in each measurement module, gears in an automatic range conversion circuit at the front end of the data acquisition component are divided into a 0-5mA gear and a 0-25mA gear, and the automatic range conversion circuit at the front end of the data acquisition component is controlled by a single-chip microcomputer to automatically convert the range gears. A high-power direct-current stabilized power supply is arranged in the power supply / control box, and a desktop industrial computer is adopted as the computer.

Description

technical field [0001] The invention relates to the technical field of pressure transmitters, in particular to a test device for an aging test system of a high-precision pressure transmitter. Background technique [0002] With the advent of the Industry 4.0 era, the vigorous development of automation and other industries has provided a broad development platform for the pressure transmitter industry. Pressure transmitters are widely used in industrial automation fields such as coal, petroleum, chemical industry, electric power, metallurgy, light industry, and military industry. [0003] The pressure transmitter (sensor) is a precision electronic measurement product. The temperature drift of the internal electronic components has a great influence on the performance and stability of the product. In order to ensure the performance stability of the pressure transmitter and obtain high-precision measurement results, It is necessary to carry out aging test on the product, and ca...
