Fiber Optic Temperature Sensors: Principle of Operation & Applications

As the name suggests these sensors employs fiber optics technology to function. A fiber optic sensor generally guides light to and from a measurement zone where the light is modulated by the measurand of interest and returned along the same … Read more

How Interferometers are used as Position Sensors

Interferometer sensors employ energy in the form of light or sound to make precise position/location measurements. There are a number of applications where accurate measurement of very small linear mechanical displacements and distances between objects in the order of nanometers … Read more

Photoelectric Pressure Transducer Operation

The photoelectric pressure transducer uses a phototube and a light source (either a stable source of light or ac modulated light) separated by a window, whose aperture is controlled by the force summing device of the pressure transducer as illustrated … Read more

What is Calibration of the Sensor?

Calibration of the sensor is the relationship between the physical measurement variable input and the signal variable output for that specific sensor. Typically, a sensor or an entire instrument system is calibrated by providing a known physical input to the … Read more
