How can you tell if a proximity sensor is inductive or capacitive
Difference in the material of the object to be detected determines the choice for the type of proximity sensor. For example, a capacitive proximity sensor may be suitable for a plastic object; an inductive proximity sensor always requires an object made of ferrous metal.

Some common disadvantages of conventional ultrasonic sensors include limited testing distance, inaccurate readings, and inflexible scanning methods. All of these drawbacks, however, can be mitigated and even overcome with the right NDT tools and techniques.
How accurate is ultrasonic proximity sensor
Summary on Accuracy
The more accurate ultrasonic sensors can achieve 0.1 – 0.2% of the detected range under perfectly controlled conditions, and most good ultrasonic sensors can generally achieve between 1% and 3% accuracy.
What is the voltage range of a proximity sensor
It requires a power source of from 2.5 to 5.5 volts.
Can proximity sensor measure distance
Proximity vs Distance sensors
Distance sensors can measure distance from an object. Proximity sensors, on the other hand, are used to detect objects in a particular range without specifying how far away they are.
What are the 2 main differences between inductive and capacitive sensors
Inductive sensors use changes in a magnetic field to determine the distance to the target; capacitive sensors use changes in capacitance. There are factors other than the distance to the target that can also change a magnetic field or capacitance. These factors represent potential error sources in your application.
