Capacitance Proximity Sensor Supplier
A Capacitance Proximity Sensor is a non-contact sensing device used to detect both metallic and non-metallic objects. Unlike inductive sensors, which only detect metals, capacitance proximity sensors can detect materials such as plastic, glass, wood, liquid, powder, and granular materials by measuring the change in capacitance caused by the target’s presence.
SCB Industries is a trusted Capacitance Proximity Sensor supplier in Kolkata, West Bengal, Odisha, Bihar, Chhattisgarh, Assam, Gujarat, Pune, and Vapi, offering high-quality sensors designed for reliable operation in industrial automation, material handling, packaging, and process control applications.
Our capacitance sensors are known for accuracy, stability, and long service life, making them ideal for detecting a wide variety of materials in challenging industrial environments.
Applications of Capacitive Proximity Sensors
Capacitive proximity sensors are versatile and can be used in a variety of applications, including:
- Level Detection: Ideal for detecting the presence of liquids in tanks and containers.
- Material Handling: Useful for detecting non-metallic materials on conveyors or in storage areas.
- Packaging Industry: Perfect for ensuring the correct placement of materials during the packaging process.
- Automation: Widely used in automated systems for detecting and counting objects.
The measurement of the capacitive proximity switch like this is usually one pole plate that forms the capacitor, and the other pole plate is the housing of the switch. This housing is usually grounded or connected to the housing of the device during the measurement process.
When an object moves towards the proximity switch, regardless of whether It is a conductor or not, due to its proximity, the dielectric constant of the capacitance should always change, so that the capacitance changes and the state of the circuit connected to the measuring head also changes, so that the switch can be controlled on or off. This proximity switch detects objects that are not limited to conductors, liquids or powders that can be insulated, etc.
