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 T8710 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.

Limitless connectivity.
The new T8710 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 T8710 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 T8710 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 T8710 also suitable for testing on parts with significant volumes.
All of the above, while maintaining ForTest's historic reliability.

Innovative design.
What appears to be a simple design exercise, in fact hides an in-depth study to make use and understanding of the tool as simple as possible.
The front panel is made of a single sheet of tempered glass and aluminium, which makes it extremely easy to clean, making the T8710 suitable for use in the laboratory and on the production line.
The extensive internal menus are easy to understand and the graphic interface was designed to only display important information.
Everything is exactly where it should be.
