T8980

Universal “Compliance” air leak tester with shut-off valve

In some particular situations, namely when the maximum allowable leakage is too small, the only solution is to enclose the test part inside a sealed bell jar and switch to an interception “compliance” system, such as the new T8980.

The equipment features 2 measurement branches: the first injects test air into the part under test, the second measures the pressure increase inside the cavity of the containment bell.

If the test part has a leak, it will transfer the pressure load into the bell, causing the pressure inside it to increase, which will then be detected by the leak measurement branch.

In this way, with complete safety, it is possible to use very high test pressures (even 100 bar) and detect extremely low leaks, even in the order of a few cc/h.

Visible leaks of few cc/h
Test pressure up to 100 bar
Independent measurement branches

High performance in testing
The T8980 represents the technological evolution in micro air leak detection. This technology allows comparing the test piece with a reference sample, canceling out thermal and environmental drifts. Its internal architecture is designed to maintain a resolution of 0.1 Pa, ensuring maximum sensitivity even when operating at high pressures, where traditional systems tend to lose precision.

Shielded Electronics and Measurement Stability
The heart of the equipment integrates window-centering technology and a double Faraday cage. This particular shielding protects the measurement section from external electromagnetic interference, ensuring extremely fast settling times (less than 18 ms) and constant reading stability. The result is a repeatable and reliable testing process, essential for the safety and quality of the final product.

Ergonomic design and capacitive interface
The equipment stands out for its modern design featuring a large 6.2″ LCD display. The “total glass” front panel in tempered glass not only facilitates cleaning operations, but offers tactile functionality thanks to the integrated capacitive touchscreen controller. The graphic interface allows monitoring of the entire test cycle through real-time graphs, making diagnostics and program configuration extremely smooth for the user.

Industrial integration and traceability
Designed for integration into automated production systems, the T8980 is equipped with a complete suite of connections: USB, RS232 and RS485 as standard, with expansion possibilities towards Profinet, EtherNet/IP and EtherCAT protocols. The front USB port allows simplified data management, enabling the saving of tests and parameter backups, ensuring full compliance with Industry 4.0 traceability requirements.
