Leak detector for tightness testing TECNA

Delta Rack Plus allows to perform pressure decay leak tests on automatic system and it is designed to meet the requirements of assembly equipment, with multiple test point, managed by PLC and/or Personal Computer.
Delta Rack Plus directly manages test times and pressures, the user must provide the external pneumatic circuit with filling and drain valves and pressure transducer.
Tecna supplies customized pneumatic modules upon request.
A programmable PLC controller can start the test with a single digital output and read the test result with two digital inputs.
A serial line is available for the supervision from the Personal Computer.
Delta Rack Plus is available in many versions and may be customized for any kind of test cycle and line pressure exigency.
