What Is a Liquid Filled Pressure Gauge? What is a thermocouple and where is it used How beneficial are thermocouple sensors in the automotive industry? What is a resistance thermometer? 3 Types of Compressed Air Filters The Importance of Using an Air Filter Regulator HOW TO PREVENT VIBRATION D...
An alcohol thermometer is a thermometer which utilizes the expansion and contraction of alcohol in response to temperature changes to measure the temperature. A number of different alcohols can be used, depending on the environment where the thermometer is being utilized, with ethanol being among the...
Since the advent of "Torricelli's tube," others developed the aneroid barometer that works without liquid. In this instrument, a flexible metal accordion box that resembles a bellows is partially squeezed to a medium pressure. Then, if air pressure rises, the bellows contract because the air ...

A hydrometer is a cost-effective instrument used to determine the density of liquids. Made of blown glass, it consists of a bulbous bottom weighted with lead or steel shot and a long, narrow stem with a scale. The hydrometer is immersed into the sample liquid until it floats. The density...
As a basic example, you could perform a calibration by measuring the temperature of a DUT thermometer in water at the known boiling point (212 degrees Fahrenheit) to learn the error of the thermometer. Because visually determining the exact moment that boiling point is achieved can be imprecise...
WHAT IS THERMOWELL? EXPLAIN THERMOWELL On many occasions in processing industries, it is not possible or desirable to insert a temperature sensor—that is, a thermocouple, RTD, bimetallic thermometer, glass stem thermometer, or filled system bulb—directly into the process material. A protective encl...
