SISCO universal vibrating fork level switch employs a piezoelectric crystal to vibrate the fork at its natural frequency. Immersion reduces the frequency and triggers switching. This vibrating fork level switch resists buildup, foam, and conductivity changes for reliable point level control.
Stable Switching Performance
- Maintains stable switching point regardless of media density, viscosity, or dielectric constant.
- Operates effectively in liquids, slurries, powders, and granular materials.
- Resists turbulence, bubbles, and foam interference during operation.
- Delivers consistent on/off output without routine recalibration.
Durable Construction for Harsh Environments
- Stainless steel fork resists corrosion, wear, and mechanical stress.
- Wide temperature tolerance from -40°C to +150°C.
- Pressure-resistant design supports operation up to 40 bar.
- Hermetically sealed electronics prevent moisture and dust ingress.
Applications
SISCO universal vibrating fork level switch is widely used for point level control in liquids, slurries, powders, and granular materials, including water-based liquids, viscous fluids, fine powders, and small particle solids.

Dimensions (unit: mm)
Q1: What media types can this vibrating fork level switch detect?
A1: This tuning fork level switch detects liquids, slurries, powders, and granular materials with a density above 0.1g/cm3 for solids or 0.7g/cm3 for liquids, and particle size up to 10mm.
Q2: How does this vibrating fork level switch handle sticky or coating materials?
A2: This tuning fork level switch features self-cleaning vibration that sheds most buildup, and its adjustable sensitivity compensates for moderate coating, ensuring reliable switching.
Q3: What output options does this vibrating fork level switch offer?
A3: This vibrating fork level switch provides relay, NPN, and PNP outputs, compatible with PLCs and control systems under AC 250V/4A or DC 60V/4A load.
Tips: What should be considered when installing this vibrating fork level switch?
- Avoid installation near strong vibration sources to prevent false triggering. If unavoidable, perform a self-check or restore factory settings at the installation site.
- Always hold the insulating tube, extension pipe, flange, or threaded connection when handling. Use a wrench on the hex bolt and seal threads with PTFE tape.
- Never bend, stretch, cut, lengthen, strike, or drop the fork. Do not twist the housing to tighten.
- For side-mounting, tilt the fork downward 15-20° to minimize material impact and buildup on this tuning fork level switch.
