Field of application
The Gammapilot FMG50 compact transmitter is designed for non-contact point level detection, continuous level, interface and density measurement in liquids, solids, suspensions or sludges. As the first true 2-wire loop powered compact transmitter it minimizes engineering and installation efforts.
For all kinds of process vessels, like reactors, autoclaves, separators, acid tanks, cyclones
For liquids, solids, suspensions or sludges etc.
Extreme measuring conditions, for example corrosion, abrasion, viscosity, toxicity
Process temperature: No limitation (non-invasive)
Process pressure: No limitation (non-invasive)
Housing material: 316L, aluminum
International explosion protection certificates, SIL, overfill prevention WHG
Benefits
First real 2-wire loop-powered compact transmitter minimizes engineering and installation efforts
Reduced installation and engineering costs thanks to the first 2-wire loop powered compact transmitter
Increased plant safety, efficiency and availability even under extreme process and ambient conditions
Designed according to IEC 61508 with SIL2/3 approval for all measuring tasks
