Tuning Fork Level Switch

On-site Alarm for Faster Abnormal-pressure Response

On-site Alarm for Faster Abnormal-pressure Response

A tuning fork level switch designed around “On-site Alarm for Faster Abnormal-pressure Response.” Provides clear switching, alarm or relay functions for equipment control and interlocking. The alarm, relay, switching or control function turns the measured condition into a clear action for pumps, valves, warning devices or equipment interlocks. The feature is directly relevant to storage tank, silo level and granular material projects. Respond faster to abnormal conditions and equipment control demands, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

One Level Switch for Liquids, Granules & Powders

One Level Switch for Liquids, Granules & Powders

A tuning fork level switch designed around “One Level Switch for Liquids, Granules & Powders.” Matches the measuring structure to the specified medium and operating conditions. The sensing principle and material arrangement are matched to the process medium and the applications stated in the source table. The feature is directly relevant to storage tank, silo level and granular material projects. Match the medium and process conditions of storage tank applications, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

PLC / DCS Interlocking for Automatic Filling & Discharge

PLC / DCS Interlocking for Automatic Filling & Discharge

A tuning fork level switch designed around “PLC / DCS Interlocking for Automatic Filling & Discharge.” Provides clear switching, alarm or relay functions for equipment control and interlocking. The alarm, relay, switching or control function turns the measured condition into a clear action for pumps, valves, warning devices or equipment interlocks. The confirmed values highlighted here are DC. The feature is directly relevant to storage tank, silo level and granular material projects. Respond faster to abnormal conditions and equipment control demands, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

Technical Specifications

Resonant Vibration Frequency:Standard fork: 1200Hz; Mini small fork: 2200Hz; Vibrating rod: 3800Hz


Vibration Amplitude Self-Detection:Real-time monitoring of fork vibration amplitude; triggers switch output when media dampens resonance


Adjustable Density Threshold:0.3 ~ 2.0 g/cm³ software adjustable; compatible with light foam, low-density powder and viscous slurry


Anti-Buildup Filter Logic:Built-in time delay filter (0.1~30s adjustable); suppresses temporary thin material coating and splashing false trigger


Repeatability Error:≤±1mm; consistent switching position under stable medium conditions


Anti-Foam Performance:Distinguish thin foam from real liquid surface; no false alarm for low-concentration surface foam


Mechanical Vibration Resistance:Fork structure with anti-resonance design; no false switching under tank stirring, pump vibration or pipeline shock


Self-Diagnosis Function:Built-in hardware fault detection; outputs fault signal for fork breakage, circuit failure or power loss


Output Action Mode:Independently configurable NO / NC relay logic; reverse output without hardware modification


Service Life (Mechanical Fork):≥100 million vibration cycles; no fatigue fracture under continuous long-term operation
