2110 Vibrating Fork Level Switch

Compact, low-cost vibrating fork level switch — point-level detection for liquids using fork vibration frequency change when wet vs dry. Single direct-load relay output (DPCO or PNP/NPN), no moving parts, no calibration, immune to flow turbulence and aerated/foaming liquids that defeat float and capacitance switches. Best for high/low alarms, pump dry-run protection, and overfill prevention on storage tanks. Common process connections (NPT, BSP, Tri-Clamp, flanged) and fork extensions to 4 m. The workhorse Rosemount level switch for general-process duty.
