Thermocouples function on the principle of the Seebeck effect, which states that two dissimilar metals combined at two junctions produce an electromotive force, or EMF, at the junctions. The metals ...

Designers face many chal lenges when placing thermal-sensing components in embedded systems. The first comes in choosing the temperature sensor. It is often not obvious whether a thermistor, resistive ...

Thermocouples contain two dissimilar metals bonded to form a bimetallic junction. Heat forces the junction to generate an electromotive force or voltage that corresponds to the temperature of the ...

The two most common types of temperature sensors in industrial applications are resistance temperature devices (RTD) and thermocouples. The two most common types of temperature sensors in industrial ...

When making physical measurements such as temperature, strain, or pressure, you need a sensor to convert the physical property into an electrical signal, usually voltage. Then, the signal must be ...

Electronic instrumentation called data acquisition systems (DAQs or DASs) acquire data from sensors. They are often extended to be instrumentation and control systems. This is a tutorial presentation ...

Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage. This approach usually requires a ...

Coupled with a new controller, a new temperature sensor reportedly offers more than double the accuracy of a standard unit. Watlow?s new Infosense sensor technology, in conjunction with its Series SD ...

The Pharmaceutical Technologies group has recently acquired a fibre optic temperature sensor from INFAP GmbH (München, Germany). Until now, the calibration of the TVIS response (i.e. the peak ...
