What is Oxidation Reduction Potential and How Do ORP Sensors …
2023年11月2日 · Oxidation Reduction Potential (ORP) measures the net voltage potential of excess oxidizers or reducers in a liquid. As it is a less common measurement, it can often be misunderstood. It is also referred to as "Redox" since the sensor measures redox reactions. To understand this, it is helpful to grasp the chemistry of these particles.
What is a Tachometer? - AZoSensors
2013年9月27日 · A tachometer is a sensor device used to measure the rotation speed of an object such as the engine shaft in a car, and is usually restricted to mechanical or electrical instruments. This device indicates the revolutions per minute (RPM) performed by the object. The device comprises of a dial, a needle to indicate the current reading, and ...
The Working Principle and Key Applications of Infrared Sensors
Image Credits: Dario Sabljak/shutterstock.com. An infrared sensor is an electronic instrument that is used to sense certain characteristics of its surroundings. It does this by either emitting or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion.
Working Principle of Magnetic Sensors
Working Principle of Magnetic Sensors. The magnetic sensor is made up of a chip with a magneto resistive component for detecting magnetic vectors and a magnet for magnetic vector biasing that can be recognized by the magneto resistive component. The chip utilized in the sensor may be used to detect changes in the magnetic vector.
