MSF-F115 Differential Pressure Leak Tester
Differential-pressure method, resolution 0.01 Pa
Accuracy up to ±0.05 % FS, range ±500 … ±10 000 Pa
In-house high-pressure shut-off valve for stable readings
7" touch screen, 40 test programs, 30-day data memory
RS232 / RS485 / RJ45 (Modbus TCP), PROFINET / PROFIBUS optional
4 PNP inputs and 4 outputs for fixture integration
Overview
The MSF-F115 measures leak rate by the differential-pressure method: the part and a reference volume are pressurised together, then isolated, and the pressure difference between them is monitored. Because both sides see the same supply and ambient drift, the method rejects the fluctuations that make direct-pressure testing unreliable on small leaks and large parts.
Key features
- Resolution 0.01 Pa (24-bit acquisition) – resolves leaks that a 1 Pa direct-pressure instrument cannot see
- Accuracy up to ±0.05 % FS over a ±500 … ±10 000 Pa span
- Self-developed high-pressure pneumatic shut-off valve; the valve is the usual source of drift on cheap benches
- Automatic atmospheric zero calibration and temperature compensation
- Test pressure available up to 3500 kPa, driving air 0.4 – 0.8 MPa
- Leak curve and numeric result shown together; error correction and dual-level password protection
