ENDRESS+HAUSER FTM20-AA42A Vibronic Level Switch, DPDT Relay, 19 to 253VAC / 55VDC, R1 Thread, 316L Stainless Steel

FTM20-AA42A is a vibronic point level detection Soliphant FTM20, compact limit switch with an extension tube for bulk solids with stainless steel housing (316L). This point-level switch is for applications with fine-grained or coarse-grained, non-fluidized bulk solids. The various designs mean the device has a wide range of applications. It features operational safety, reliability, and universal applicability through the use of the tuning fork-measuring principle. Measurement is unaffected by conductivity, build-up, turbulence, flows, or air bubbles.

• Simple and fast commissioning, no calibration required
• No mechanically moved parts, free of maintenance
• Safe function due to self-monitoring (active frequency monitoring of the fork)
• Easy recurring function test via test magnet, suitable for constricted space due to compact design
• Measurement not affected by build-up or external vibration, not affected by flow noises
• Non-hazardous area approval, thread EN10226 R1, 316L (process connection)
• 225mm sensor length
• ATEX, FM, CSA, CSA C/US, IEC Ex, NEPSI, INMETRO, EAC certificates / approvals
• 200g/l minimum density of medium, international explosion protection certificates
• Process temperature range from -40°C to 150°C
