Product Sheet
Flexibility:ET97W represents the ideal instrument in order to execute seal in flow tests, but it can be also used to execute flow in air tests
on parts with great volumes.
Speed:
Advanced electronics, revolutionary algorithms of calculation and optimization of the pneumatic circuit, allow to execute tests in very short times.
Easy usage:
Simplest user interface, outcome of the visual test, indication GOOD/BAD, flow value indicated in real time on display, bargraph
with indication of flow percentage; location without errors of nonstandard details.
Connection:
3 expansion connectors allow ET97W to connect with PC, PLC, local printers, automatic and semi automatic stations, FOR TESTŠ accessories.
The leak detector ET97W represents the best solution on the market in terms of precision, flexibility and execution speed of seal tests with measure in flow rate.
This instrument allows to measure in a direct way the air flow generated by the leak-off rate.
ET97W is composed of a pneumatic circuit optimized in order to reduce the filling times, of a mass flow sensor, of a pressure
sensor and of an electronic pressure regulator, that guarantees stable and safe test pressures without the operator assistance.
The instrument detects the leaks through continuous seal measure of the pressurized piece, this method allows to reduce
drastically the time of the test phase.
ET97W is specially used in seal tests where the volume of the piece is unknown and variable (oil motors, elastics bags or
bottles), when the leak entity is so elevated that a Δp system does not succeed to maintain constant the test pressure (cartridge valves, oil distributors, between filaments) and finally when is requested a continuous leak measurement in order to allow the operator to look for and repair the same one.
