Level switch LBFS-2.01111.0, G 1/2" A ISO 228-1, PNP, AISI 304, M12 connector with LED

LBFS-2.01111.0 is a capacitive point level switch from the Baumer CleverLevel series with a G 1/2" A ISO 228-1 BSC process thread. The Frequency Sweep measuring principle sets the switching point from the dielectric constant of the medium (DC > 1.5), and the device carries two independent outputs, SW1 and SW2, each set separately to High-Active or Low-Active logic.

• Switching: point level detection, Single Point, Two Point and Window trigger modes, hysteresis < ±1 mm, repeatability < ±1 mm
• Output: two PNP outputs (SW1, SW2), each separately High-Active or Low-Active, 50 mA, step response T90 0.1 s, adjustable damping 0...60 s
• Supply: 8.5...35 V DC, current consumption < 8 mA (typ.)
• Housing: stainless steel; wetted parts PEEK Natura and AISI 304 (1.4301), Ra ≤ 0.8 µm
• Environment: process temperature -40...115 °C (135 °C temporarily), process pressure -1...100 bar (-1...80 bar temporarily), IP67 and IP69K with a matching mating connector
• Connection: M12-A, 4-pin, polycarbonate connector with status LED indicators

The switch is intended for tanks and pipework in industrial plant with a G 1/2" internal thread and pressures up to 100 bar. Mounting position is free - top, bottom or side. Damping of up to 60 s is set so that surface movement or splashing does not cause false switching.

The PEEK material complies with USP Class VI. cULus listed, E365692. Marine approvals: DNV, Lloyd's Register and CCS. EMC compliance to EN 61326-1 and EN 50121-3-2.
