What is a Three-wire RTD ?

A compromise between two-wire and four-wire RTD connections is the three-wire connection, which looks like this: In a three-wire RTD

Four Wire RTD Circuit

What is a Four-wire RTD ?

A very old electrical measurement technique known as the Kelvin or four-wire method is a practical solution to the problem

Filled-bulb Temperature Measurement

Filled-bulb Temperature Sensors

Filled-bulb systems exploit the principle of fluid expansion to measure temperature. If a fluid is enclosed in a sealed system
