Leak measurement with flow sensor
Leak display in volumetric mode (cc/h or cc/min) with a classic leak testing tool is restricted by setting the volume of the piece being tested which, using mathematical algorithms, allows conversion of the pressure decay in volumetric decay.
To release this system from restrictions, the flow leak tester T9710 was designed which, using one solid-state and one pressure sensor, displays the leaks detected directly in volumetric mode, with no need to set the volume being tested.
This characteristic makes it extremely versatile in the event of large volume variables being tested, and particularly intuitive in the analysis of test cycle progression.

Advanced interface.
For us, the T9000 series is the most technologically forward of measurement systems, equipped with an advanced interface, useful for analysis and research during the prototyping or pre-series phase, as well as for production line testing.
The big, 7” colour display set in a capacitive glass panel allows total interaction with the internal menus and the main screen. The "smart" testing archive contains daily and monthly analysis functions and those specifically for each test program, to keep the level of quality of your products under control.

Limitless connectivity.
The new T9710 equipment includes ports for the USB slave, RS232, RS485, Can bus and TTY. Assembly may also include an optional Ethernet port and a 26-pole connector with 4 inputs and 8 outputs, which are completely programmable, for interfacing with the external valves, safety barriers, switches, etc...
The front panel has a master USB port assembled on it for connection to a USB key to save the tests conducted, backup/restore parameters and upgrade tool firmware.
The connection to thermal printers, barcode/data-matrix readers and markers takes place automatically using an internal menu.

Hybrid functioning.
The particular operation of the T9710 consists of continuous injection of test air, unlike a classic leak testing system, and directly measures the leak flow, which varies from a few cc/min to various hundredths, based on the application.
This system makes the tool suitable for measuring leaks which go beyond the classic leak testing scales, but which are not close to the normal flow test values, which normally arise to measure thousands of cc/min of leaking; this is why the nature of the T9710 is a hybrid between to technologies.
Measurement resolution starts with 0.1 cc/h based at the bottom of the scale, varying from 50 to 1,000 cc/min, with maximum pressure of 1 bar.

Made to measure pneumatic section.
To avoid overheating due to long activation times of the filling circuit, we have designed particular, high capacity pneumatic valves, which not only work in hot temperatures, but also quickly fill the piece being tested, making the T9710 also suitable for testing on parts with significant volumes.
All of the above, while maintaining ForTest's historic reliability.
