Vacuum leak tester F28 LPV

absolute pressure decaypneumatichydraulic

Overview
The F28 LPV is a vacuum decay / pressure decay leak tester from ATEQ’s F28 range. It is a compact, industrial-grade unit designed for installation close to the test part to maintain optimal measurement conditions. The unit is programmable and supervised via the F28 Control interface.

Applications

• Packaging and blister testing
• Watches and small consumer devices
• Mobile phones and electronic enclosures
• Pneumatic and hydraulic fittings

Key features

• Pressure decay leak measurement (vacuum)
• Water leak detection by evaporation under strong vacuum
• Smart pressure regulation without external regulator – auto fill (optional)
• Electronic regulation option
• Measurement units: Pa, Pa/s, sccm, µg/min (H2O)
• Compact overall dimensions: H 141.5 x L 225 x D 97 mm
• Integrated fill and dump valves
• Ethernet network support up to 50 modules (Modbus TCP/IP)
• DIN-rail mounting
• RoHS compliant

Measurement characteristics
Pressure drop measurement (absolute): range 0.05 to 110 kPa — resolution 1 Pa — accuracy*: 2% F.S.
Vacuum decay: range up to 2000 Pa — resolution 1 Pa — accuracy*: 2% F.S.
*Accuracy = linearity + repeatability + hysteresis

Technology
The standard pressure decay method compares the sealed part pressure with atmospheric pressure using a piezo pressure sensor. It detects small pressure variations and is suitable for applications where ultra-high accuracy or extremely short cycle times are not required.
