The capacitive sensor is a element which converts the variation of the measured non-electricity signal value into capacitance variation for non-contact and non-defective detection of metal (conductor) and nonmetal (non-conductor). The capacitive sensor features simple design and good dynamic response characteristics. It is applicable for automatic sensing in metallurgy, petroleum, chemical, meteorological, aerospace, and other industries.
Capacitive sensor is a element that converts the variation of the measured non-electricity signal value into the change of capacitance. It can detect metal (conductor) and non-metal (non-conductor) and is always used to detect non-metallic objects such as liquids (like acid, water, oil), and granular objects (such as grains and flour).
The capacitive proximity sensor consists of high frequency oscillator and amplifier. When an object comes to the sensing surface of the sensor, the capacitance of the oscillator circuit changes. The two states of oscillator, i.e. oscillating and stop oscillating, are converted into electrical signals, which are converted into binary switching signal by the amplifier as output. It is mainly used as a detector installed on an automatic industrial assembly line.
The inductive proximity sensor is composed of high-frequency oscillating, wave detecting, amplifying, triggering and output circuits. As a metal object approaches the sensing surface of the sensor, the oscillation on/off status is converted to electrical signals, which are converted to binary digital signals after being amplified by the shaping power amplifier. This inductive proximity sensor is mainly installed in the automatic assembly line.
Inductive sensor is a device that uses the change of coil self-induction or mutual induction to realize measurement. It is mainly used for sensing the displacement and the mechanical variables. The inductive sensor is suitable for automatic detection in metallurgical, machine tool, metal processing and other industries.
The inductive sensor is used for sensing the metal objects by measuring the variation of coil self induction or mutual induction coefficents. It is mainly used for automatic sensing in metallurgical, machine tool, metal processing and other industries.
With magnetic field as a medium, this magnetic induction sensor converts magnetic or other physical quantity signals to electrical signals. magnetic induction sensor is always used for measurement (such as speed measurement) as driven by a permanent magnet, or used for control (such as position control) as driven by an electromagnetic coil.
Magnetic induction sensor is a device that can convert various magnetic fields and their varying quantities into electrical output. Mainly used to monitor the magnetic target, but also through the metal, to monitor the magnetic target installed in the metal.
Capacitive sensors are used for non-contact and wear-free detection of metallic (conductive) and non-metallic (non-conductive) in the applications of position detection, overflow detection, leak detection or pump idling protection, as well as level monitoring of liquid and bulk goods.
