Capacitive Sensor (A sensor that detects metal, non-metal, and all types of liquids)
Object detection sensors are important devices that enhance the efficiency of modern automated systems. Capacitive Sensors or capacitive sensors stand out for their ability to detect a wide variety of objects including metals, non-metals, and liquids without contact. At SCMA we are the official sole distributor of ifm electronic in Thailand, equipped with a team of experts to advise on selecting detection systems that meet your needs.
What is a Capacitive Sensor?
A proximity sensor is a non-contact object detection sensor for industrial use. A capacitive sensor is one type that can detect both metals and non-metals, including plastics, water, wood, glass, and dust. It uses the principle of an electric field and capacitance; when an object enters the detection range, the capacitance value changes causing the sensor to signal immediately. Suitable for liquid level monitoring, seed or plastic pellet counting in silos through sight glasses with precision.
How Capacitive Sensors Work
Capacitive sensors use a front plate capacitor and ground to create an electric field via an oscillator continuously. When an object enters the electric field, capacitance increases causing the circuit to oscillate and signal status change. Detection capability depends on the dielectric constant of materials, type and size of objects, as well as distance. Learn more about capacitive sensor technology.
Types of Capacitive Sensors
How many types are there? There are several types based on their operation. Capacitive sensors can be categorized by installation type and purpose:
General Proximity Sensor (Capacitive Proximity Sensor)
Standard proximity sensors detect objects both metallic and non-metallic up to a range of 5-50 millimeters through electric field changes when an object enters. Suitable for position detection on conveyor belts, counting workpieces, or checking products in packaging.
Insertion Type Level Sensor
Capacitive sensors with probe insertion measure liquid or solid levels inside containers. When material level touches the probe, capacitance changes and signals are sent. Suitable for small storage tanks, silos, or pipelines requiring precise point-level measurement.
Submerged Type Level Sensor
Sensors submerged in liquids measure continuous liquid levels without additional probes by converting pressure into level data. Suitable for deep wells, large tanks, or high-precision water treatment systems.
