Basics of Limit switches

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

Communication-grade optical fibers are manufactured from fused silica (SiO2) glass of exceptional purity. A single strand of optical fiber made

An optical fiber is a “pipe” through which light flows. This is, of course, merely an analogy for how an

Electronic signals used in traditional instrumentation circuits are either DC or low-frequency AC in nature. Measurement and control values are
