Abstract

The invention discloses a depth meter demarcation detection device. The device is applicable to demarcation detection of a depth meter which is a pressure sensor or a current sensor. The device comprises a computer installed in a case and is provided with a lateral protection cover, a table type air pressure pump and a digital pressure calibrator. The pressure pump adopts an air pressure mode, the pressure pump is clean and free of pollution, a pressure value of the pressure pump is displayed through the pressure calibrator to ensure that the detected depth meter can be subjected to detection of performance parameters under the specified air pressure, and a detection result is processed through the computer. The depth meter demarcation detection device is simple in structure, good in operation performance, convenient to detect and capable of conducting demarcation detection on the depth meter and outputting detection reports quickly and provides a detection basis for production inspection and acceptance and actual use of the depth meter.

Description

technical field

[0001] The invention relates to a depth gauge calibration detection device, which is suitable for the calibration detection of the depth gauge as a pressure or current sensor. The detection device performs calibration detection on the depth gauge through a desktop air pressure pump and a digital pressure calibrator; the detection result is processed by a computer. And finally output the detection report. Background technique

[0002] Usually, the depth gauge needs to be tested during production or actual use, and the test report is manually filled out according to the test results whether the depth gauge is working normally. Traditional technical means or detection equipment are poor in operability and the detection process is cumbersome; pressure pumps mostly use oil pressure and are easy to pollute depth gauges; there are many detection cables, poor reliability, bulky and heavy, and inconvenient to move; long detection cycle and inflexible .
