Use method of non-weight calibration to calibrate underwater load cell

and explore effect of confining pressure on underwater load cell. As special working condition

it ’s difficult to calibrate underwater load cell accurately. Using loading calibration system consists of special load machine

high-precision digital pull-pressure sensor and intelligent instrument

solve the problem of underwater load cell calibration and effect of confining pressure using method of curve fitting

process data in real-time. The calibration system has many advantages such as easy operation

good stability

high precision

and can meet requirements of underwater load cell calibration.
