Vibrating Tuning Fork Level Switch With Digital Display

The BROTEK MAKE Smart Vibrating Tuning Fork Level Switch is a versatile and intelligent level switch that uses a piezoelectric crystal to excite the fork body into a resonance state. When the fork contacts the material, the resonance frequency changes significantly, allowing the internal electronic unit to detect the frequency and convert it into a relay or PNP switch output.
