Flow Testing Systems
For applications that demand direct airflow measurement, ForTest's flow testing solutions offer a dependable and accurate method of leak detection. By assessing airflow across a component, this method quickly identifies leaks with stabilization times as short as 100-300 milliseconds, making it an efficient solution for fast-paced production lines.
A-Tech offers a variety of ForTest flow testers, tailored to different industry needs:
Standard level equipment
High-Level Equipment
The flow testing system provides several operational advantages, including rapid stabilization and continuous measurement, making it a preferred choice for applications where minimizing testing time is critical. Additionally, ForTest flow testers utilize high-quality differential transducers and laminar flow elements to achieve linear measurement characteristics, ensuring accuracy even in turbulent conditions.
Differential Decay Leak Testing
The Differential Decay Leak Testing system by ForTest is designed for cases where highly sensitive leak detection is needed, particularly in environments with varying pressure conditions or where high-pressure tests are required (above 20 Bar). This system measures the difference in pressure between the test component and a reference sample, allowing precise leak detection by identifying even small deviations.
ForTest's differential systems are an excellent choice when the application demands high sensitivity and accuracy, especially in conditions where absolute decay systems might struggle due to thermal or mechanical noise.
- T6961 - Differential Remote Entry-level Leak Tester: Designed for flexible setups, offering remote differential leak testing capabilities.
- T8060 - Differential Leak Tester: A versatile solution for standard industrial applications that require stable and precise differential pressure measurements.
- T8980 - Compliance Differential Tester: Ensures compliance with stringent industry standards through advanced differential analysis.
- T4960 - Micro Differential Bench Leak Tester: Ideal for testing small parts with high precision, particularly in micro-volume applications where accuracy is critical.
The differential decay system uses a complex pneumatic circuit to mitigate thermal and mechanical influences, providing high measurement repeatability and stability. Despite its complexity, this method remains invaluable for specific applications that require extremely fine sensitivity in the detection of leaks.
The T8997 leak and flow tester combination unit allows for both leak and flow testing with the same unit, bringing the cost to implement down, as well as increasing efficiency. By sharing the CPU, the communication interface and electronic pressure regulator are shared and there is much less mechanical work to integrate.
