The Deltapilot FMB51 rod sensor uses the CONTITE measuring cell with a fixed process connection and is mainly used in the environmental sector to measure the level of liquid or paste-like media in open or closed vessels, with measurement unaffected by foam. The design complies with IEC 61508 and meets SIL2 functional safety requirements.
Advantages
Excellent repeatability and long-term stability
Turndown ratio: 100:1
Fully sealed CONTITE measuring cell: condensation-resistant, weather-protected; high reference accuracy: ±0.2%, optional: ±0.1%; minimal temperature influence
Point-to-point modules for measuring differential pressure, static pressure and pressure (Deltabar M - Deltapilot M - Cerabar M), e.g. replaceable display, universal electronics
Simple commissioning without operating tools
Areas of application
Hydrostatic sensors can be used for the following measurements:
Hydrostatic measurement of liquid and paste-like media in the process industry, process measurement, pharmaceutical and food industries
Measurement of liquid level, volume or mass
