Abstract

The invention discloses a series sensor and a measuring method, which are composed of a large-range sensor, a high-precision small-range sensor, a sensor protection device, a connection structure of various components and a waterproof device. The invention connects the high-precision small-range sensor and the large-range sensor through a unique connection structure, and sets a sensor protection device to protect the high-precision small-range sensor, and also provides waterproof protection for the sensor by setting a waterproof device. The beneficial effects of the present invention are: effectively solve the problem of inaccurate measurement of axial force in a small range when measuring a large range of axial force, and can effectively measure the axial force in each range; for improving geotechnical triaxial tests under high pressure The test accuracy of has important value. Using sensors with different ranges and designing different mechanical structures can meet the requirements of measuring pressure or tensile pressure under various environmental conditions above or below water.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a serial sensor. In particular, the components, assembly form, protection and waterproof sealing treatment, and sensor usage methods of the series sensor all relate to this field. The invention can be applied to the research and development of instruments in geotechnical engineering and mechanics, as well as related tests in this field. Background technique [0002] According to the current sensor test error regulations, it can be seen that the larger the measuring range, the greater the error value of the sensor, especially in the range of small measuring ranges, which will produce non-negligible errors. The test accuracy of the small-range sensor is high, but the test range is limited, and it cannot test a large external load. Based on the above requirements, there is an urgent need for a mechanical sensor capable of testing any range, and the test accuracy must meet certain ...
