CLO - "Open-Style" capillary leaks

Features

VTI's CLO model calibrated gas leaks have a stainless steel capillary that has been precision crimped to provide an accurate flow-rate restriction for any gas. These "open-style" or "in-line" leaks do not have a reservoir of gas but, instead, use an external gas source. Under pressure, gas flows through the capillary restriction into the system or part being tested. This yields a precise, known flow rate based on the inlet and outlet pressures.

The CLO leaks are available welded into a tube and welded into many different inlet and outlet attachment fittings. In addition, these capillary leaks can be built into an actual or simulated test part that can then periodically be put through a regular test cycle to validate and calibrate the entire leak test system. This is the only way to be sure that the total test procedure is finding the leaks that lead to product failure. A separate brochure provides additional information.

These open-style leaks can be calibrated at one inlet pressure (your test pressure) to obtain a single specified leak rate. Alternatively, they can be calibrated at several inlet pressures, usually three, to obtain different leak rates and the ability to vary the rate within a range (usually 10x) of values using the calibration curve of pressure vs. leak rate provided.

Choosing the CLO Calibrator

  • CAN BE CALIBRATED WITH ANY GAS - or mix.
  • UNBREAKABLE - all stainless steel, all welded.
  • WIDE LEAK-RATE CHOICE - use for large leak rate app's.
  • SINGLE OR ADJUSTABLE LEAK RATES - can be calibrated at one or multiple pressures/rates..
  • STABLE - low temperature coefficient of 0.2% / °C.
  • CAN BE BUILT INTO A PRODUCTION TEST PART - to simulate a defect with a specific leak rate.
  • BAKEABLE FOR UHV USE - using all metal fittings.
  • MEETS ISO REQUIREMENTS - NIST-traceable, A2LA-
    accredited Calibration Certification.
