FTL31-GR4U3BAWSJ Endress+Hauser - Liquiphant Point Level Switch

The FTL31-GR4U3BAWSJ is an Endress+Hauser Liquiphant FTL31 point level switch for liquids, using a vibrating tuning fork to detect level in tanks, vessels and pipes regardless of conductivity, buildup or turbulence.

This GR4U3BAWSJ configuration is the same Liquiphant FTL31 platform as the AA4U3BAWSJ build, differing in process connection and approval options selected through the Endress+Hauser product configurator; confirm the exact connection thread and material certificate against the order code at purchase. The sensor detects liquids above roughly 0.7 g/cm3 density (0.5 g/cm3 optionally) and is available in 3-wire DC-PNP (10 to 30 VDC) or 2-wire AC/DC (20 to 253 VAC/DC) electronic versions, switchable between maximum-safety (MAX) and minimum-safety (MIN) operating modes with a fail-safe quiescent-current principle. The housing is 316L stainless steel, optionally fitted with an M12x1 plug for IP69 protection, rated for process temperatures up to 100 or 150 degrees C depending on configuration. Not suitable for hazardous areas; the FTL33 variant is recommended for hygienic duty.
