Choose from 5 different leak test methods
One of the many benefits of the LTC-503 is its impressive flexibility as an entry-level leak tester. It is uniquely capable of operating one of 5 different leak test methods.
The Pressure Change Method (A) with absolute/relative pressure sensors is one of the simplest and most reliable methods for leak testing. The test object is subjected to overpressure or vacuum, and the pressure change over time is recorded.
PRESSURE CHANGE TEST TYPES
- Pressure/Vacuum Decay - Leak Standard
- Pressure/Vacuum Decay - ΔP
- Pressure/Vacuum Decay - ΔP/ΔT
- Blockage Detection
- Membrane Test
- Hold pressure
- Stagnation pressure
Review the LTC-503 datasheet for detailed specifications.
The dosing method (D), also known as the “closed component” method, is used for completely closed components such as watches, cell phones or control units. The test specimen is placed in a measuring chamber (bell jar) and sealed. This chamber is pressurized via an evacuated or filled pre-volume. A leak in the test specimen changes the pressure ratio, which is detected by a pressure transducer (DA) or pressure difference sensor (DR).
DOSING METHOD TEST TYPES
- Pressure/Vacuum Decay - Leak Standard
- Pressure/Vacuum Decay - ΔP
- Pressure/Vacuum Decay - ΔP/ΔT
- Blockage Detection
- Dosing method (D)
- Membrane Test
- Hold pressure
- Stagnation pressure
- Automatic volume determination (C) option
Review the LTC-503 datasheet for detailed specifications.
As an alternative to the dosing method, the volume determination (C) is used to determine the volume of the test specimen. It offers the same pros and cons as the closed component approach.
A known pre-volume is filled or evacuated with a known test pressure and then expanded in the test specimen. The volume of the test specimen is determined with the resulting pressure.
The principle of volume determination can also be integrated into other measurement methods.
The Pressure Differential Method (R) with reference volume is the most common method for leak testing. A reference volume – either a small internal volume or an external volume such as a master test specimen - is pressurized together with the test specimen. After the stabilization time, the pressure change between the two volumes is measured using a highly sensitive pressure difference sensor.
PRESSURE DIFFERENTIAL TEST TYPES
- Pressure/Vacuum Decay - Leak Standard
- Pressure/Vacuum Decay - ΔP
- Pressure/Vacuum Decay - ΔP/ΔT
- Blockage Detection
- Membrane Test
- Hold pressure
- Stagnation pressure
