Helium mass spectrometer leak detector vs differential pressure leak detector: which one is more suitable for your leak detection needs?

Date:2023-07-28 Views:1632

The helium mass spectrometer leak detector and the differential pressure leak detector are two common methods for gas leak detection, and there are some differences between them, along with their respective advantages and disadvantages.

Differences:

Principle: The helium mass spectrometer leak detector uses helium as a tracer gas and determines the leakage location by detecting the change in the concentration of helium around the leakage point. The differential pressure leak detector, on the other hand, is based on the differential pressure principle and determines whether there is a leak by measuring the gas pressure difference near the leakage point.

Sensitivity: The helium mass spectrometer leak detector usually has high sensitivity and can detect very small leakage amounts, even reaching the level of 10^-12 milliliters per second. The sensitivity of the differential pressure leak detector is relatively low, and it is generally suitable for the detection of large-scale leaks.

Application Scope: The helium mass spectrometer leak detector is suitable for the detection of various gas leaks, including combustible gases, inert gases, and toxic gases. The differential pressure leak detector is mainly used to detect the leaks of gas pipelines, containers, and sealing systems.

Advantages and Disadvantages:

Advantages of the Helium Mass Spectrometer Leak Detector:


  1. High Sensitivity: It can detect very small leakage amounts.
  2. Multi-gas Applicability: It is suitable for the detection of various gas leaks. High Accuracy: It can accurately locate the leakage position.
  3. Real-time Monitoring: It can monitor the leakage situation in real time.
  4. Long-distance Detection: It is suitable for complex or hard-to-reach equipment and pipelines.


Disadvantages of the Helium Mass Spectrometer Leak Detector:


  1. High Equipment Cost: It is relatively expensive and requires professional operators.
  2. Use of Helium: It requires the use of helium as a tracer gas, increasing the cost and operational complexity.
Advantages of the Differential Pressure Leak Detector:
  1. Relatively Inexpensive: The price is relatively low.
  2. Simple and Easy to Use: The operation is simple, and no special gas is required.
  3. Suitable for Large-scale Leaks: It has a good effect on the detection of large-scale leaks.


Disadvantages of the Differential Pressure Leak Detector:


  1. Low Sensitivity: It cannot detect very small leakage amounts.
  2. Inaccurate Leakage Location: It cannot accurately locate the leakage position.
  3. No Real-time Monitoring: It requires manual detection and cannot monitor the leakage situation in real time.
