Tuning Fork Level Switch | Ring-21CTBRCS | 1-1/2" NPT | Relay Output | 10~35V DC

Tuning Fork Level Switch — Ring-21CTBRCS

The Ring-21CTBRCS Tuning Fork Level Switch is a precision point-level detection instrument engineered for reliable liquid and solid level sensing in demanding industrial environments. Its vibrating fork technology eliminates the need for moving parts, delivering maintenance-free, drift-free performance across a wide range of process media — from clean water to viscous liquids and fine powders.

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 — simple, robust switching output for direct integration with PLCs, control panels, and alarm systems
• Supply voltage: 10~35V DC — wide voltage range for flexible power supply compatibility
• 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 without special approvals

Typical Applications

• High/low level detection in storage tanks
• Pump protection (dry-run prevention)
• Overfill protection systems
• Water and wastewater treatment
• Chemical and process industries
• Food and beverage processing
