Reference: supplied LBFS datasheet, 2018-03. Temperature, pressure, materials and approvals vary by order code. Check the current manufacturer datasheet before ordering. Do not apply LBFS-2 or LBFI specifications to a legacy LBFS.
A point switch does not provide continuous level accuracy. Check switching behavior in the actual medium.
Specify more than the sensor
Request the process adapter, seal, M12 cable and electrical interface with the sensor. Confirm every supplied item in the quotation; accessories and certificates are not automatically included.
Choose the exact LBFS connection
The supplied 2018 sheet distinguishes industrial G½ connections, hygienic G½ variants, cooling-neck options, NPT threads and a sliding connection. For example, the standard industrial LBFS-xx1xx.x reference is −40 to +115 °C at −1 to 100 bar, while the hygienic LBFS-xx4xx.x reference is −40 to +115 °C at −1 to 10 bar. These are different configurations.
The sliding hygienic LBFS-xxLxx.x reference reaches +200 °C at up to 5 bar, subject to the projection-length and ambient-temperature chart. It must not be advertised as a 200 °C / 100 bar product.
Foam, coating and media differentiation
Frequency sweep evaluates the electrical response near the tip. Teach-in and switching-window settings can help distinguish media in a suitable application. A reliable result requires enough separation between the actual process states; dry foam, wet foam and residual film are not interchangeable test conditions.
Legacy LBFS, LBFS-2 and LBFI are different families or generations. Interface, load capacity, response time and approvals must follow the current datasheet for the complete order code.
