Problems solved by technology

[0002] Pressure instruments are instruments installed on site. Due to their large number and prone to failure, the amount of repair and maintenance is very large. Now the maintenance of pressure instruments is on-site maintenance, which is to calibrate instruments such as indicators, regulated power supplies, Standard pressure gauges, pressure calibrators, etc. are brought to the site. Due to the large number of equipment and complicated wiring, and there are often no mains sockets on site, the maintenance work is not only cumbersome but also not safe enough, and the quality of inspection is difficult to guarantee. The second is to remove the pressure gauge. It is not only inefficient but also inconvenient to take it to the instrument calibration room for calibration

Abstract

The invention discloses a portable pressure instrument calibrator, and belongs to the field of automation instrument calibration instruments. The calibrator is characterized by comprising a box body and a panel, wherein the panel is provided with a pressure regulation valve, an inspection valve, a micrometering valve, a first pressure gauge, an output pressure connector, a digital display meter, an output current connector, a power control, a power connector, a resistor network and a pressure transmitter support. The upper portion of the box body is provided with a handle and a second pressure gauge. A check valve, a high-pressure air cylinder, an air filtering pressure reducer, a storage battery, a support, a high-pressure air pipe and an output pipeline are installed in the box body. An air source connector is arranged on the side of the box body. The portable pressure instrument calibrator has the advantages of being compact in structure, convenient to carry, easy to operate and quick and precise in calibration.
