Capacitive Sensors for Accurate Point Level Detection of Liquids & Bulk Solids

Capacitive Sensors provide dependable point level detection for liquids, powders, granules and bulk solids by sensing changes in capacitance. They are ideal for industries that require reliable level switching, process automation and inventory control across diverse materials.

ADYAA supplies and distributes Capacitive Sensors in Australia, helping industries improve point level detection, process reliability and production efficiency through advanced sensing technology.

From storage tanks and silos to hoppers, pipelines and process vessels, Capacitive Sensors deliver versatile level detection for conductive and non-conductive materials without relying on moving mechanical parts.

What Are Capacitive Sensors?

Capacitive Sensors are point level sensors that detect the presence or absence of material by measuring changes in electrical capacitance between the sensing probe and the surrounding medium.

Unlike vibration or mechanical switches, Capacitive Sensors can detect liquids, powders, granules and interface levels, making them suitable for a wide variety of industrial applications.

They support:

Point level detection
High-level alarms
Low-level alarms
Tank level monitoring
Hopper level detection
Process automation

Using capacitive sensing technology helps improve process reliability while reducing manual intervention.

How Capacitive Sensors Work

A Capacitive Sensor continuously monitors changes in electrical capacitance. When the material reaches the sensing area, the capacitance changes and activates the switching output.

Typical process:

Sense → Detect → Switch → Control → Protect

Example:

A food processing facility installs Capacitive Sensors in ingredient hoppers to automatically detect refill levels, helping maintain uninterrupted production and reducing material shortages.
