Calibration labs that calibrate high-temperature probes can use the Hart Scientific Model 5624, a 10-ohm platinum resistance thermometer (PRT). The probe's sensor design makes it a suitable standard ...

Temperature is one of the most frequently measured physical quantities, and features prominently in many of our projects, from weather stations to 3D printers. Most commonly we’ll see thermistors, ...

Palmer-Wahl Instrumentation Group has introduced a new series of Italcoppie-brand RTD probes that the company says offer long-lasting, accurate temperature measuring in harsh operating conditions and ...

An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to 20mA ...

The old saying “if it ain’t broke, don’t fix it” cautions against tampering with something that performs reliably and regularly proves its worth. Arguably, this advice applies to the circuit design ...

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 ...

AutomationDirect has added new ProSense temperature probes, sensors, and thermowells to their existing portfolio of process sensors. Four new probe designs and three new sensor designs are offered to ...

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 ...

In automotive testing, temperature measurement is often performed at multiple positions. Large rolls of thermocouple wire are required to perform temperature measurements in and around a plastic ...
