Instruments Used For Measuring Temperature

Updated april 05 2018.

Instruments used for measuring temperature. The liquids chosen for thermometers expand and contract significantly. Italian physicist evangelista torricelli is credited with inventing the barometer in 1643. Relative to what you ask. A barometer is a weather instrument used to measure air pressure.

They all measure temperature by sensing some change in a physical characteristic. Temperature instrumentation includes a wide range of field instruments and sensors used to measure temperature in commercial and industrial systems. A thermometer is the foundation instrument for any weather measurements. The thermometer you use to take your temperature when you re sick isn t much help when measuring the temperature of melted lead.

These temperature control systems include manual and automatic processes for monitoring and controlling the temperature to maintain an ideal operating range to optimize production and prevent. Temperature measuring sensors come in a wide variety and have one thing in common. The word thermometer basically means heat meter. The seven basic types of temperature measurement sensors discussed here are thermocouples resistive temperature devices rtds thermistors infrared radiators bimetallic devices.

Of the two main types of barometers mercury and aneroid aneroid are more widely used. You can also choose from 1 year 5. Instruments for measuring temperature. Of the many different methods of temperature measurement available the instrument engineer in the process industry is only likely to encounter a handful.

Atop the bulb is a stem that has a scale marked for measuring the temperature. A thermometer will give you an indication of the relative energy as heat in the air around it. Most people would say that thermometers measure temperature and that s true but there are many different kinds. As the name suggests the instrument consists of a glass bulb containing a special liquid.

The liquid in glass thermometer is one of the most common instruments used today to measure temperature. Moreover some things. There are many different ways to measure temperature all of which infer temperature by sensing some change in a physical characteristic.
