The relative slip between the square steel tube and the core concrete was measured using the steel strip extracted from the slotted steel tube and the displacement meter attached to the independent bracket.
The stress test at the junction of the retaining wall and the surrounding rock of the karst cave was based on the JMZX-5010am intelligent pressure cell and the JMDL-3210A single-point displacement meter. Figure 15(a) shows the test results of 3 pressure cells in the front, middle, and rear of the top of the retaining wall, while Figure 15(b) shows the test result of the horizontal displacement meter in the middle point of the retaining wall.
As indicated, there existed no displacements in the soil at the time of 400 seconds, during which the WY1 displacement meter remained zero and mean no decompression.
The vibration amplitudes of the pizeoelectronic transformer measured with a laser displacement meter (LC-240, Japan) were around 0.10 [micro]m.
The PSD's pneumatic cylinder and positive displacement meter are lightweight and assembled into a single compact metering module for floor, robot or pedestal mounting.

However, such single-aperture laser interferometers as a Laser Doppler Displacement Meter (LDDM) can be used.
Compound meters contain, within a single casing, a displacement meter section for measuring low flows, a turbine meter section for measuring high flows, and an automatic compounding valve.
For instance, the displacement meter A3 is 9.8 mm when the load is 50 kN, and displacement meter A3 is 17.1 mm when it is 97 kN.
The displacement and load were measured using a wire-type displacement meter with the maximum length of 500 mm and a hollow cylindrical load cell with a capacity of 200 kN.
A positive rod displacement design is said to eliminate the normal reload cycle of a standard rod displacement meter system and maintains the precision metering and long life features of positive rod displacement.
Using Optodyne's Laser Doppler displacement meter (LDDM), the sequential step diagonal or vector measurement, 12 sets of data can be collected by the four sequential step diagonal measurements.
