Leakage leak tester B28

vacuumhigh-voltagefor seal integrity

Overview
The B28 is a compact, high-speed leak tester designed for battery cells and breathable membranes. It provides a rapid insulation/leak go/no-go check using an air ionization method and can be configured to control filling and dumping vacuum in a dedicated enclosure for optimal measurement conditions.

Applications

• Battery cell production and testing
• Automotive components

Features

• Leak measurement using air ionization method (I max <1 mA)
• Compact form factor for tight integration
• External vacuum source with integrated fill and dump valves (optional control)
• Ethernet network support up to 50 modules (Modbus IP)
• DIN-rail mounting
• Environment: ROHS compliant

Measurement ranges
Test | Range | Max resolution
Test voltage | 50 – 750 VDC | < 1% F.S.
Leak | 0 to 100 000 pts | < 1% F.S.
Pressure | 0.5 kPa to ATM | < 1% F.S.
*Accuracy: linearity + repeatability + hysteresis. Optional laboratory accuracy available.

Technology
The instrument applies a high-voltage sharp electrode near an earth-connected base with the tested plastic part between them. If a hole exists, ions move from earth to the sharp end producing a measurable current loss, indicating a leak. This ionization-based method delivers the fastest detection for go/no-go processes (cycle times < 0.7 s). Leak sensitivity and accuracy depend on hole size and part material; the method monitors presence and relative magnitude rather than volumetric flow (cc/min).
