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 ...

This user guide gives the operation of Intersil’s precision products in a temperature sensor application. Also, this provides a functional description on how it works. Moreover, the guide indicates ...

The vendor’s ProSense line of process sensors now includes 0.25-inch RTD temperature probes. The three-wire, 100 ohm platinum RTD probes are made of durable 316 stainless steel and measure ...

Before running a formal test with multiple resistance temperature detector (RTD) sensors, it is often necessary to calibrate and debug a data-acquisition system to verify basic functionality. The ...

Temperature transmitters are employed to transmit a signal from a temperature sensor, such as a RTD or thermocouple, to a control or measurement device. These temperature transmitters amplify and ...

The UWRTD-NB9W wireless RTD probe/ transmitter assembly features a stainless steel probe connected to a polypropylene watertight transmitter housing. The assembly is shipped ready to install and ...

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 ...

In this first article in a two-part series, we discuss resistance temperature detector (RTD) circuit design for a functionally safe system and introduce considerations for the Route 2S component ...
