Float level switch Principle

Some level switches use a float to sense the level of a liquid surface, actuating an electrical switch by the

Another electronic liquid level switch technology is capacitive: Sensing level by changes in electrical capacitance between the switch and the

A pressure switch is one detecting the presence of fluid pressure. Pressure switches often use diaphragms or bellows as the

A limit switch detects the physical motion of an object by direct contact with that object. An example of a

Perhaps the simplest (and oldest) form of electrical level detection is where a pair of metal electrodes contacts the process

An Optical Time-Domain Reflectometer or OTDR is a sophisticated test instrument used to probe the characteristics of long optical fibers.

Fiber optic cable testing is done to ensure all installed cable lengths and connectors are functioning properly.

One of the most popular styles of single-fiber connector is the so-called “ST” style, which uses a quarter-turn locking barrel

In any sort of waveguide – optical, electrical, or even acoustical (sound) – the signal energy may be able to

Fiber Optic Sensing Applications Optical fibers find applications beyond electronic data cable replacement, though, which means they will be a
