FAQ

What is the minimum conductivity required for the L3 to operate?

The Anderson-Negele L3 is factory-set to a sensitivity of 10 microSiemens/cm, but it can be adjusted to trigger on liquids with conductivity as low as 1 microSiemens/cm, making it suitable for a wide range of products including demineralized water.

Yes, absolutely. The L3 is designed specifically for hygienic applications. Its robust stainless steel construction and high-quality seals make it fully compatible with standard Clean-in-Place (CIP) and Sterilize-in-Place (SIP) procedures, withstanding high temperatures and cleaning agents.

The exact wiring depends on the specific order code, which is not fully visible on this unit. The L3 series is available with various outputs including DC PNP/NPN and AC/DC relay outputs. It is crucial to consult the datasheet or test the unit to confirm the output type before installation to prevent damage to the sensor or your control system.
