Tuning Fork Level Switch | Ring-21CTBRCS | 1-1/2" NPT | Relay Output | 85~253V AC

Tuning Fork Level Switch — Ring-21CTBRCS (AC Version)

The Ring-21CTBRCS Tuning Fork Level Switch (AC-powered) delivers the same proven vibrating fork reliability in a version designed for standard AC mains supply. Whether you're protecting a pump from dry-running, preventing tank overfill, or triggering a process alarm, this switch integrates seamlessly into any 85~253V AC control system — covering everything from 110V to 240V installations without additional transformers or converters.

Key Features

• Tuning fork (vibrating fork) technology — no moving parts, no calibration required for most media
• Wide temperature range: -50°C to +100°C — suitable for both cold and hot process applications
• 1-1/2" NPT threaded process connection — standard fitting for easy installation in tanks and vessels
• Relay output — robust switching output for direct integration with PLCs, control panels, and alarm systems
• Supply voltage: 85~253V AC — universal AC range covering 110V and 220/240V systems
• Stainless steel wetted parts — corrosion-resistant construction for aggressive media and hygienic applications
• Compact DIN connector — industry-standard electrical connection for quick wiring
• Standard configuration — suitable for general-purpose level detection
