SD-2Type Digital Load Cell Indicator
(1) Brief Introduction:
This factory is a manufacturer ofSD-2Manufacturer of the model digital point load tester, the first to adopt instrument data sampling. Our data sampler is an intelligent unit that integrates a digital pressure sensor and a liquid crystal display, capable of capturing the peak value at the moment and simultaneously displaying real-time pressure data. It avoids measurement errors caused by the inherent linear error of mechanical pressure gauges and human visual errors during rock point load tests, especially solving the issue of human eye reaction time lag during instantaneous failure. It achieves real-time and accurate sampling during testing. The instrument is designed with imported components, high-precision pressure sensors, and has the following features::

(3) Main Functions:
1Rock point load test
（1Features:Point load test involves placing a rock specimen between two spherical conical plates, applying a concentrated load to the specimen until failure, and then determining the point load strength of the rock based on the failure load.
Point load strength can be used as an indicator for rock strength classification and rock mass weathering classification, and it can also be employed to evaluate the degree of anisotropy in rock strength, as well as to predict other related strength indicators such as uniaxial compressive strength and tensile strength.
（2The loading system consists of a pressure oil pump, a pressure-bearing frame, and a spherical cone-shaped pressure plate. The oil pump output
Approximately 100 horsepower60kNThe loading frame has sufficient rigidity to ensure resistance under repeated maximum load application.
No permanent distortion or deformation; spherical end conical plate with spherical curvature radius of5mmPyramidal top angle
