FTL31-AA4M3AAWBJ Compact Tuning Fork Level Switch DC10-30V

This compact tuning fork level switch is a professional industrial point level limit detection device. Adopting vibration damping detection principle, it accurately identifies liquid presence without being affected by bubbles, turbulence and medium viscosity. Made of high-quality 316L stainless steel, it features corrosion resistance, high pressure and high-temperature resistance for harsh industrial conditions. Designed with ultra-low power consumption, it supports DC10-30V wide voltage power supply and PNP signal output.
