Non-Contact Liquid Level Sensor - Output Options

Detect liquid at a chosen point through a suitable non-metallic container wall with a capacitive level sensor offered in several output versions.

✅ Sense without opening the container - External capacitive detection offers an arrangement without placing the probe directly in the liquid.

✅ Match the electrical output to the host - NPN, PNP and high/low-level selections provide different interface choices.

✅ Set the sensing point for the vessel - A sensitivity-setting procedure helps configure the probe at its mounted position.

Choose the output and supply as a pair

A level switch indicates liquid at the sensing position rather than measuring the full volume in a tank. Mount the probe on a suitable non-metallic wall and follow the setup procedure using the actual container and liquid.

Output versions have different voltage and connection requirements. Select the exact NPN, PNP or high/low type alongside the receiving electronics; the high/low version is a logic input accessory and must not be assumed to drive a relay directly.
