| The working principle | The CETATEST 815 Twin differential pressure leak detector adopts a dual-channel synchronous operating system and is suitable for workpieces that can be tested with the same Settings to achieve specific adjustment of leak limits. Pressure attenuation in the volume of the test piece due to leakage compared to the pressure in the reference volume (differential pressure method) |
| Mode of operation | Dual channel synchronous operation, single channel mode |
| Signal processing | Fast 24-bit analog-to-digital conversion Real-time processing of measurement signal process |
| The valve type | Seat valve |
| Process control | Real-time microcontroller system, 16 bit μC / 40 MHz |
| The sensor | Each channel contains a differential pressure sensor and a relative pressure sensor |
| Measuring range | ± 500 Pa / ± 5.000 Pa (resolution: 1 Pa); Other ranges are subject to request |
| The unit display | Pa, hPa, psi, Pa/s. hPa/s, mbar*l/s, ml/min, ml/h, l/min, l/h |
| Test pressure range | -1 bar, 200 mbar, 1 bar, 6 bar, 10 bar,
Negative gauge pressure and positive gauge pressure can be integrated (e.g. -1 bar / +1 bar), other as required |
| Test mode/test options | Pressure drop, pre-inflation, smooth inflation |
| System control | The supply of compressed air is ensured by self-test controlled by differential pressure sensor |
| In case a test cycle breaks in one channel (for example, a significant leak), the test cycle continues in the other channel |
| Programmable test phase | Delay, pre-inflation, pre-discharge, inflation, stabilization, measurement, discharge |
| Test schema specific bounds | Precharge pressure, charge pressure, stable pressure (depending on firmware), test mode specific nonconformance and rework class |
| operation | The menu is intuitive and user rights are protected by password |
| Parameters of the stored | 64 separate alphabetical and numeric test program parameters can be imported and exported through test ports or USB storage devices |
| Additional features | Detailed result statistics, cycle counter, maintenance interval display, counter, parameter change record, measurement times and curve record, programmable RS-232 interface |
