FAQ
- A level sensor is the wetted part of a level measurement system: the float, probe, transducer, or antenna that interacts with the liquid or solid. In casual use 'level sensor' often refers to the complete device (sensor plus electronics). Strictly, a sensor outputs a raw signal, while a switch outputs a contact and a transmitter outputs 4-20 mA or digital.
- Contact sensors physically touch the fluid (floats, displacers, conductive probes, guided wave radar). Non-contact sensors measure from above without touching (ultrasonic, through-air radar, laser). Contact gives you more options for difficult media but exposes the sensor to fouling, corrosion, and damage. Non-contact keeps the sensor safe but can struggle with foam, vapor, dust, and condensation on the antenna. Pick based on the process, not based on a general preference.
