Helium Leak Sensor
A Helium Leak Sensor or Helium Leak detector is used to locate and measure the size of leaks into or out of a system or containing device. The tracer gas, helium, is introduced to a test part that is connected to the leak detector. The helium leaking through the test part enters through the system and this partial pressure is measured and the results are displayed on a meter.
Product & engineering
Understand the product.
A Helium Leak Sensor or Helium Leak detector is used to locate and measure the size of leaks into or out of a system or containing device. The tracer gas, helium, is introduced to a test part that is connected to the leak detector. The helium leaking through the test part enters through the system and this partial pressure is measured and the results are displayed on a meter.
Helium leak detectors consist of the following components:
A spectrometer to detect the mass of helium
A vacuum system to maintain the pressure in the spectrometer
A mechanical pump to evacuate the part to be tested
Valves which enable the various stages of detection: evacuation, test & venting
An amplifier and readout instrumentation to monitor the output signal
Power supplies and controls
Fixturing that attaches the part to be tested to the detector
Methods of Leak Testing Parts
There are two main methods to leak test parts using helium: Vacuum Testing (outside-in) and Pressure Testing (Inside-out). The detection method should be selected based on the working conditions of the part to be tested. It is important to maintain the same pressure conditions during the test as will exist during the actual use of the part. Vacuum systems should be tested with a vacuum inside the chamber. A compressed air cylinder should be tested with high pressure inside the cylinder.
