Tuning Fork Switches

8 Products
316 SS Mini-Type Tuning Fork Level Switch

The piezoelectric component produces the resonation on the fork. When the fork comes into contact with a material, the fork will release some frequency signal as feedback

Threaded, Flanged, Tri-Grip Tuning Fork Level Switches

The LTU-2000 Tuning Fork Sensors are point level switches that are designed to detect low or high levels of liquids and is based on the vibrating tuning fork principle.

316 SS Fixed Length Standard-Type Tuning Fork Level Switch

The LTUR-3022 is a tuning fork level switch. When the measured medium comes into contact with the tuning fork, it will change the feedback resonant frequency.

VRLS Vibrating Rod Level Switch for Powders & Bulk Solids Detection

The VRLS Vibrating Rod Level Switch detects powders and bulk solids with adjustable sensitivity. Its self-cleaning design ensures accurate detection without maintenance.

Mini Tuning Fork Level Switch – PNP/NPN Output for Powder Monitoring

The Mini Tuning Fork Level Switch offers reliable PNP/NPN output, perfect for monitoring powder levels. Compact design ensures easy integration in various applications.

Compact Tuning Fork Level Switch for Powders - Adjustable, Vibration Immune

The Compact Tuning Fork Level Switch is designed for powders, featuring adjustable settings and immunity to vibrations for reliable performance.

Polyphenylene Sulfide, NO or NC Tuning Fork Level Switch

The LTU-101A-R consists of a sensor with dual tuning forks vibrated at a high frequency. As the tuning fork is covered by liquid, a shift in frequency activates the relay.

Tuning Fork Level Switch for Powders, Immune to Vibrations, No Calibration

The Tuning Fork Level Switch for Powders offers reliable performance without calibration, designed to be immune to vibrations for consistent level detection.

Tuning Fork Switches

Tuning Fork Switches detect level by monitoring a vibrating fork or rod as material contacts the sensing element. Products in this category span Omega Engineering and Dwyer Instruments liquid tuning fork switches, threaded, flanged, and Tri-Grip designs, 316 stainless steel mini and standard styles, powder-focused compact tuning fork switches, vibrating rod switches, and bulk solid detection products.

Applications include:

  • Liquid high and low point detection
  • Powder and fine-grained solid level control
  • Bulk solids in silos, hoppers, and process vessels
  • Applications where low-density material may not suit a rotary paddle switch

Choose tuning fork or vibrating rod switches by matching the sensing element, material density, process connection, output, and installation environment to the medium.
