Differential pressure decay leak tester F670LV

for containersfor vesselsfor automotive applications

Overview
F670LV is an instrument for leak testing very large volumes (up to 200 L) using a patented Differential Noise Canceling (DNC) method based on Differential Pressure Decay and a high-sensitivity pressure transducer. With the ATEQ F670LV and DNC, pressure drops below 0.1 Pa/sec can be detected, enabling reliable testing of large, flexible parts and assemblies.

Applications

• Parts with very large volumes such as tanks and large enclosures
• Electric vehicle battery housings and other large EV components sensitive to background noise
• Integration into test benches and production lines for end-of-line or in-process testing

Features

• 128 programs for process flexibility
• Large-flow valves for fast filling and handling of parts
• Fully integrated electronics and pneumatics for compact installation
• Flexible communications: RS232, USB; optional Fieldbus modules
• Environment: ROHS compliant

Measurement characteristics

• High-sensitivity pressure transducer enabling detection of very small pressure drops (below 0.1 Pa/sec with DNC)

Control interface

• WINATEQ 300 graphical control interface for program management and data handling

Technology

• DNC (Differential Noise Canceling) compensates for background disturbances to provide faster, more accurate leak readings in noisy factory environments

Factory disturbances addressed by DNC

• Temperature variations (doors/windows opening, HVAC)
• Pressure variations (time of day, weather)
• Vibrations (machine movement, forklifts, nearby activity)

Leak reading improvement
The DNC function stabilizes leak readings by compensating background disturbances so they do not influence the leak measurement sensor.
