It can be used in conjunction with display, acquisition and recording device to realize process monitoring.
.
2 uses
WGJ type settlement instrument is embedded digital output type settlement instrument. It is mainly used for earth rock dam, rockfill, road, ground or fill the internal settlement, especially suitable for continuous observation of deformation of concrete face rockfill dam, and automatically collect and record data.
The sensor WGJ type settlement gauge is a high precision (+ 0.5mm), high resolution (0.1mm), photoelectric switch, rotary encoder and high reliability, the output data is a linear change, no time and temperature drift, sensor performance is far better than other types of.
Show level sensor, the instrument can be directly with the recorder installed various types of pipe settlement device (for example: NSC-100 type settlement instrument) supporting the use of artificial observation, records for automatic observation, recording, and improve the measuring precision.

3 structure and working principle
WGJ type settlement instrument consists of settling bag, settling plate (settlement base), connecting pipe, digital level, digital acquisition, display and so on. Its working principle is: buried within the dam settlement settlement package with an overflow pipe and the ventilation pipe with pipe is communicated with the observation room level is connected, when the settlement package sink, settlement package produce overflow overflow, and through the drain dam. When the settlement points overflow, the water level of the level falls synchronously. The change of water level of observation level is equal to the change of settlement elevation of observation subsidence point. The observed value is added to the settlement of the observation chamber itself, which is the actual settlement value of the settlement point.
It is the amount of leveling type rotary encoder, photoelectric switch, float, barrel level measuring cable, power output socket and other components, the output signal is gray 12 ~ 15bit range is 0-100mm to 0-16m, the resolution is 0.1mm to 0.5mm, can meet different needs of observation.
The level sensor with parallel gray output, RS485/232 output (optional), 4-20mA current loop (optional) output, can be easily with a variety of display and recorder supporting the use of automatic observation, automatic recording to achieve settlement point.
