Four wires good, two wires bad

Original article date: September 1997
The relative merits of 4-wire and 2-wire signal/power transmission configurations in industrial sensors are the subject of some debate among controls and plant maintenance engineers.
In the 4-wire scheme, a pair of twisted wires is dedicated to the precise transmission of a 4-20mA current signal linearly proportional to the variable being sensed, [...]

Conductive Inclination Sensor

Original article date: May 1996
Whether it be in the fields of measurement technology, precision tools, plant machinery or control, often the most important thing is to monitor horizontal measurements or measure angles. So many engineers have a need to measure angles of inclination with absolute accuracy.
Conductive inclination sensors are based on the idea that, when [...]

The root of the cable extension transducer

Original article date: November 1997
Roy Moffatt, Managing Director of Variohm Components, explains the basics of the cable extension transducer and how the CET originally came about.
It is possible to deploy one or more methods to measure position on machines or equipment. Cable extension transducers (CETs) are just one of these. They are used to measure [...]
