Product Overview
The HTR2820 Passenger Coach Axle-End Grounding Device Spring Pressure Test Bench is a specialized inspection system that integrates pressure sensors and microcomputer control technology. It is specifically designed to detect the spring pressure and average value deviation of the four carbon brushes within a grounding assembly.
The device can simultaneously measure all four spring pressures and their deviations in a single test cycle. By utilizing system software for comprehensive data analysis, it can accurately identify jamming or mechanical binding within the grounding device.
