The E+H FTL31-1E40/40 belongs to Endress+Hauser Liquiphant FTL31 compact vibronic tuning fork series, operating based on resonant frequency shift principle of piezoelectric-driven tuning fork for reliable point-level detection of homogeneous liquids with minimum medium density ≥0.7 g/cm³. This specific 1E40/40 variant is equipped with ISO G1 threaded process connection, integrated IO-Link + 3-wire PNP switching output, full 316L stainless steel wetted component and compact all-metal housing without explosion-proof certification for non-hazardous general industrial sites. The built-in continuous self-diagnosis circuit monitors fork vibration status in real time to avoid false switching caused by component failure; no on-site calibration or parameter tuning is required after installation to realize plug-and-play commissioningEndress+Hauser. Unaffected by liquid conductivity, surface foam, medium adhesion and pipeline turbulence, this unit widely serves mechanical processing, hydraulic station, fine chemical and water treatment industries for tank overflow prevention and pump dry-running protection.
