For Liquids
LIQUIPOINT
Vibrating point level switch for liquids

A robust point level sensor with tuning fork for industrial process technology. Designed for overfill and dry run protection, virtually unaffected by the chemical and physical properties of the liquid. No calibration required.

  • Fast switching response
  • Compact fork length (100mm)
  • No calibration required
  • Insensitive to external vibrations and buildup
  • Configurable viscosity setting and switching delay
  • Selectable fail-safe mode
  • Works in high viscous mediums (e.g. tomato ketchup)
Water Soap Ketchup Juices Cream Paints Milk Epoxy Resin Honey Gasoline Beer & Wine Solvents
For Bulk Solids
SOLIPOINT
Vibrating point level switch for fine-grained bulk solids

A robust point level switch for silos with fine-grained bulk solids and free flowing powders. Ideal for coarse products and heavier loading conditions than a vibrating rod device. Sensitive only at the tip, minimising the effect of build-up on tank walls.

  • Fast switching response
  • Compact fork length (100mm)
  • No calibration required
  • Insensitive to external vibrations and buildup
  • Configurable viscosity setting and switching delay
  • Selectable fail-safe mode
  • Rugged design for heavy loading conditions

HOW IT
WORKS


01

Piezoelectric Energization

A piezoelectric crystal energizes the vibrating fork element, causing it to oscillate at its natural resonance frequency of 350–390 Hz.

02

Frequency Shift Detection

When the fork is submerged in a product, the oscillation frequency changes due to damping. The electronics module detects this shift instantly.

03

Switching Command

The detected change is converted into a precise switching command — triggering alarms, controlling pumps, or interfacing directly with your control system.

04

Fail-Safe Output

Selectable High/Low fail-safe mode ensures your process stays safe even in the event of a sensor fault — configurable right on the field.
