Piezometers are the geotechnical sensors that are used to measure pore water pressure (piezometric level) in the ground. It is designed to measure pore water pressure in the soil, earth/rock fills, foundations, and concrete structures. The piezometer or pore pressure meter provides significant quantitative data on the magnitude and distribution of pore pressure and its […]

As per Michael Faraday, electric current can be generated by a magnetic field. According to Faraday’s law of electromagnetic induction, whenever a conductor is placed in a magnetic field, an emf is induced which is called induced emf. Two field coils are located inside of the magnetic flowmeter with the help of pole shoes. These coils generate

Measuring temperature is a crucial part of any industrial process system operation. Unfortunately, thermometers are not designed to withstand especially harsh environments. All thermometers are susceptible to damage from flow, corrosion, abrasion, temperature, pressure, and turbulence, whether they are mechanical (i.e. bimetal or gas actuated thermometers) or electrical (i.e. thermocouples or resistance temperature detectors). A

What is Resistance? Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current, and resistance. He is credited for formulating Ohm’s

A thermocouple is a temperature sensor that is used to gauge temperatures in manufacturing, machining, and scientific applications, as well as everyday appliances. A thermocouple can be useful to ensure surfaces, like steel or other metals or metal alloys, are appropriately heated for machining, or to gauge when a container or location is too warm
