Customer ServiceCapacitive sensors are versatile and can sense a variety of materials, including both metals and non-metals. Inductive sensors are more specialized and can only detect metal objects. When it comes to the sensing distance, inductive sensors have a shorter range compared to capacitive sensors.
Customer ServiceIntroduction: Both capacitive and inductive sensors offer non-contact sensing capabilities. These sensor types rely on changes in physical properties to detect objects. Capacitive sensors measure change in capacitance while inductive sensors measure change in electromagnetic fields.
Customer ServiceThe sensor which detects changes in capacitance to determine the presence or proximity of objects is known as capacitive sensor. They offer non-contact sensing and are unaffected by material of the detected object.
The sensor detects this change and outputs a signal. Because of this principle, inductive sensors are exclusively used for detecting metal objects, such as steel, aluminum, and copper. Capacitive sensors operate based on the principle of capacitance change. These sensors create an electrostatic field between two electrodes.
There are different types of capacitive sensors which include the following. This type of capacitive sensor is available in a wafer or a cylindrical shape that can be placed in the most compact places. These sensors are mainly used to monitor and control, machine processes & work like detectors used for job counting.
Robust Sealing: To withstand harsh environments, both inductive and capacitive sensors are designed with excellent sealing properties. They are typically resistant to water, dust, and oil, ensuring reliable operation even in demanding industrial conditions.
The output is inversely proportional to the size of the sensor capacitor. Larger sensor capacitors charge the integration circuit faster and require fewer switching operations to reach the threshold voltage. Alternatively, one can replace the comparator with an analog-to-digital converter.
Capacitive sensors, while versatile, are more sensitive to environmental changes. Factors such as humidity, temperature, and the presence of dust can influence their accuracy and performance. In applications where environmental conditions fluctuate, additional calibration or protective measures may be necessary to maintain consistent performance.
