Accurate Calibration Instrument For All Types Brake Tester

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:

1. 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

2. 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

3. 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

4. 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?

1. 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.

2. 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.

3. 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.

4. 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.
