Product Description

Product Introduction

The YTPC01 integrated settlement and inclination instrument is a high-precision measuring device, compositely built from a pressure-type hydrostatic level and an inclinometer. It can be used to monitor multi-point relative settlement and inclination, that is, the change in vertical displacement of each measuring point relative to the reference point. The settlement system consists of multiple sensors of the same model. The devices are interconnected via air tubing and liquid tubing, with the reference point located at a stable horizontal datum. When a measuring point rises or falls relative to the reference point, it will cause pressure variations at each point. The integrated settlement and inclination instrument calculates the vertical displacement of each measuring point relative to the horizontal datum by measuring the pressure variations in the sensors.

Main Components:

Exhaust Valve
Vent Port, Liquid Port
5-core Waterproof Aviation Connector
Intelligent Circuit Module
Sealed Aluminum Alloy Housing
Precision Pressure Core Body

Measurement accuracy: refers to the error between the liquid level data measured by the sensor and the actual liquid level data.
Resolution: refers to the minimum change value of the measured object that the sensor can detect and distinguish within the measurement range.
Storage temperature and humidity: Store in a suitable ambient temperature and humidity for daily preservation. Long-term storage in such an environment will not affect the service life of the equipment.

Working Principle

The Pressure-type Static Level consists of a liquid storage tank, bracket, connecting pipe, and other components. Based on the communicating vessels principle, a relatively stable reference point is set. When settlement occurs at a certain point, it will cause pressure changes at each point. By measuring the pressure changes of the sensor and converting them into liquid level changes, the elevation changes of each measuring point relative to the horizontal base point are calculated.
