Product Overview:instruction
of roller brake tester& axle load cali...
This calibration device is a universal calibration system designed
to verify the accuracy and performance of various types of brake
testing equipment, including roller, plate, and deceleration (road)
brake testers.
By simulating known braking forces and loads, it ensures that the
sensors, electronic units, and software within the test system
deliver reliable and traceable measurement results.
The calibration system typically includes a mechanical loading
mechanism, force sensors, standard weight sets, and alignment
tools.
Applicable Equipment Includes:
Roller Brake Tester
Plate Brake Tester
Deceleration / Road Brake Tester
Key Features:
Compatible with multiple types of brake testers (roller, plate, deceleration)
Uses mechanical or hydraulic loading to simulate real braking forces
Equipped with high-precision force sensors or torque meters (accuracy ≤ ±1%)
Adjustable mounting structure for easy alignment and adaptation to different equipment
Optional traceable calibration certificate certified by a metrological institution
Usage Instructions:
Preparation Stage
Ensure the brake tester is clean, functioning properly, and set to calibration or maintenance mode
Set up warning signs or barriers to prevent unintended operation during calibration
Install the Calibration Device
Roller Brake Tester: Attach the calibration bar or torque arm to the roller shaft
Plate Brake Tester: Place the force sensor or standard weights on the test plate
Deceleration Brake Tester: Apply reference braking force using a dynamic simulation device
Apply Known Load or Braking Force
Use the calibration device to apply a known load or torque to the testing system (e.g., 1000 N or 2000 Nm)
Record the readings from the test system and compare them with the actual applied values from the calibration device
Comparison and Adjustment
Calculate deviation or error
If deviation exceeds allowable tolerance (e.g., ±3%), adjust internal parameters of the tester (such as software scaling or sensor offset)
Repeat the test until measured values match the reference values
Why is Calibration Necessary?
Ensure Accuracy of Brake Test Results
Brake test precision directly affects vehicle safety. Uncalibrated equipment may overestimate or underestimate braking performance, leading to incorrect evaluations.
Comply with Legal and Technical Standards
National and international standards (e.g., GB21861, ISO 21069, EU 2014/45) require regular calibration of brake testers to ensure valid vehicle inspections.
Identify Sensor Drift or Mechanical Wear
Sensors and mechanical structures may change over time. Regular calibration helps detect and correct errors promptly to avoid potential risks.
Provide Traceable and Auditable Test Records
For inspection centers and commercial repair facilities, complete calibration records serve as proof of equipment reliability and compliance, fulfilling audit and certification requirements.
