Capacitive Proximity Sensor Advantages And Disadvantages

It has longer life.

Capacitive proximity sensor advantages and disadvantages.

It can withstand harsh environmental conditions. Following are the advantages of capacitive sensor. There are many types each suited to specific applications and environments. The major application of capacitive sensor is level sensing as mentioned above.

Advantages ultrasonic proximity sensors are not affected by atmospheric dust snow rain etc can work in adverse conditions sensing distance is more compared to inductive or capacitive proximity sensors disadvantages ultrasonic sensors has more difficulties reading reflections from soft curved thin or small objects. It can detect through containers of certain types also. The capacitive proximity sensor consist a high frequency oscillator along with a sensing surface formed by two metal electrodes. Capacitive proximity sensor diagram advantages disadvantages capacitive sensor.

Proximity sensors detect the presence or absence of objects using electromagnetic fields light and sound. Refer proximity sensor of inductive type for more information. Capacitive can withstand below temperature of 0 o c it does not require any maintenance for longer periods flexibility to use atm. Pressure independent it works when pressure is being applied it has limited long term stability.

Following are the advantages of inductive sensor. Refer capacitive sensor basics and working for more information. It is sensitive to dewing and certain aggresive substances. A transducer that uses capacitance variation is known as capacitance sensors.

Advantages of capacitive sensor. When an object comes near the sensing surface it enters the electrostatic field of the electrodes and changes the capacitance of the oscillator. Machine tools to sense metal targets etc. Advantages of inductive sensor.

Humidity sensing method advantages disadvantages. Inductive sensor is used for wide variety of applications viz. Working principle of capacitive proximity sensor. It can be used to detect non metallic targets.
