Endress+Hauser Soliphant FTM20 Vibronic Point level detection

• Operational safety, reliability and universal applicability through 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

Point level switch in compact design with stainless steel housing.
