Problems solved by technology
However, according to market research, most manufacturers of pressure gauges currently use manual testing for pressure gauge pressure testing methods, and because pressure gauges not only need to perform positive pressure testing, but also need to perform negative pressure testing, but most manufacturers The factory uses two sets of equipment for positive pressure detection and negative pressure detection, which requires money to buy two sets of equipment. The labor cost is too high, and the manual test speed is slow and inefficient, which increases the production cost of the pressure gauge.

The invention relates to a digital display pressure meter test device. The test device comprises a test platform, the test platform is in sequence provided with an air filter, air pressure switches, air pressure solenoid valve and at least one group and above test units connected through a windpipe, the test platform is further provided with a PLC control circuit board and control button components connected with the input end of the PLC control circuit board, the output end of the PLC control circuit board is electrically connected with the pressure solenoid valve. By the digital display pressure meter test device, positive air pressure and negative air pressure of the air pressure meter can be digitally displayed, and tested one by one relative to the manual work, testing is conducted by batch by one person alone using the product, work efficiency is increased, labor costs are reduced, at the same time, under the effect of the PLC control circuit board, manual and automatic test modes can be achieved, and the selections are provided for the staff.
Description
technical field [0001] The invention relates to the technical field of instruments, in particular to a testing device for a digital display pressure gauge. Background technique [0002] Pressure gauges are widely used in industrial automation. In the production process of pressure gauges, in order to ensure the quality of pressure gauges, the first thing to do is to test the pressure gauges to ensure the safety of the products. However, according to market research, most manufacturers of pressure gauges currently use manual testing for pressure gauge pressure testing methods, and because pressure gauges not only need to perform positive pressure testing, but also need to perform negative pressure testing, but most manufacturers The factory uses two sets of equipment for positive pressure detection and negative pressure detection, which requires money to buy two sets of equipment. The labor cost is too high, and the manual test speed is slow and inefficient, which increases t...
