Robust point level switch with extension tube for fine-grained bulk solids also for hazardous areas

Field of application

Soliphant FTM51 is a robust point level switch for use in silos containing fine-grained or powdery solids even with a low bulk density. Suitable for a wide range of applications with international certificates for use in dust or gas hazardous areas. Available with polished fork and stainless steel housing with Tri-Clamp or with aluminum housing and coated fork. Maintenance-free device for use in typical applications like: cereals, flour, cocoa, sugar, animal feed, dye powder, chalk.

Point level switch for fine grained solids and powder.

  • Process connections: Threads, flanges and hygienic connection (Tri-Clamp)

  • Temperature: -50 to +280°C (-60 to +540°F)

  • Pressure: -1 to +25bar (-14.5 to +360psi)

  • Sensor length: 300mm to 4,000mm

  • Sensor material: 316L (3,2µm, 0,8 µm, PTFE coated, ETFE coated)

  • International explosion protection certificates

Benefits
