    AI Overview
    Relay helium leak detection units are specialized, high-sensitivity systems that use mass spectrometers to identify, quantify, and locate microscopic breaches in relay housings, ensuring hermeticity for critical components . These units, such as the INFICON Modul1000 or specialized units for relay inspections (EVP vacuum pump), typically use a vacuum chamber to test components after they have been filled with a helium tracer gas, allowing for both fine and gross leak detection .
    Key Aspects of Relay Helium Leak Detection:
    • Methodology: The process involves filling the relay with helium, then placing it in a vacuum chamber. If a leak exists, helium escapes and is detected by a mass spectrometer, ensuring the seal's effectiveness .
    • Techniques:
      • Vacuum Method: Ideal for high-precision testing (fine leaks) where the component is placed in a chamber .
      • Sniffer Method: Uses a probe to pinpoint the exact location of the leak .
    • Industrial Application: Used to test relays, contactors, and sensors for the automotive and electrical industries, often identifying leaks at a level of
      10−7
      mbar
      ⋅l/s
       or smaller .
    • Key Components: A system usually includes a mass spectrometer, vacuum pumps, an inlet system for gas, and a calibrated leak for verification .
    These systems often enable automated testing, where components that fail are automatically separated, helping to maintain high production quality .
