Technical details and manufacturing context for Thickness Measurement Sensor

Definition
A precision measurement component integrated into Battery Electrode Calendering Machines that continuously monitors and provides real-time feedback on the thickness uniformity of electrode materials (anodes and cathodes) as they pass through the calendering rollers, ensuring consistent electrode density and quality in battery manufacturing.
Working Principle
Typically uses non-contact measurement technologies such as laser triangulation, eddy current, or capacitive sensing to detect the distance between the sensor and the electrode material surface, calculating thickness based on reference points and calibration data.
Common Materials
Stainless steel housing, Optical glass lenses, Electronic circuit boards, Copper wiring
Technical Parameters
  • Measurement range and accuracy for electrode thickness (mm) Standard Spec
Components / BOM
  • Measurement Probe
    Directly interacts with or senses the electrode material surface to detect thickness
    Material: Stainless steel or ceramic
  • Signal Processor
    Converts raw sensor data into digital thickness measurements
    Material: Electronic components on PCB
  • Communication Interface
    Transmits thickness data to the calendering machine control system
    Material: Copper connectors and wiring
Engineering Reasoning
0.1-500 μm with ±0.1 μm resolution at 1000 Hz sampling rate
Measurement error exceeds ±0.5 μm or response time degrades beyond 10 ms
Design Rationale: Laser diffraction pattern distortion due to electrode material particulate contamination exceeding 5 μm particle size at 100 particles/cm³ concentration
Risk Mitigation (FMEA)
Trigger Calender roll thermal expansion exceeding 15 μm at 150°C operating temperature
Mode: Non-contact laser triangulation sensor misalignment causing 2.5 μm measurement offset
Strategy: Integrated water-cooled mounting bracket with 0.01° angular adjustment precision
Trigger Electrode material slurry splatter accumulation at 0.1 mm thickness on sensor lens
Mode: Laser beam attenuation reducing signal-to-noise ratio below 40 dB
Strategy: Pressurized nitrogen purge system at 0.5 bar with 5 μm filtration
