Technical Terms in Measurement of Power, Flow and Temperature Related Properties

Technical Terms

·       Force: The mechanical quantity which changes or tends to change the motion or shape of a body to which it is applied

·       Load Cells: Load cells are devices for the force measurement through indirect methods

·       Torque: Torque can be defined as a measure of the tendency of a force to rotate the body on which it acts about an axis.

·       Thermocouple: When two dissimilar metals are joined together, it will create an emf it is primarily a function of the junction temperature.

·       Flow meter: Flow meter is a device that measures the rate of flow or quantity of a moving fluid in an open or closed conduit.

·       Thermometry: Thermometry is the science and practice of temperature measurement. Any measurable change in a thermometric probe can be used to mark temperature levels that should later be calibrated against an internationally agreed unit if the measure is to be related to other thermodynamic variables.

·       Resistance Temperature Detectors: RTD as the name implies, are sensors used to measure temperature by correlating the resistance of the RTD element with temperature.

·       Dynamometer: A dynamometer or "dyno" for short is a device used to measure power and torque produced by an engine.
