Durex Industries has introduced an RTD temperature sensor designed for monitoring air and various gas temperatures. A machined tip designed to maximize airflow over a miniature platinum film element ...

where: R RTD is the measured RTD resistance. V ADC is the ADC voltage reading. I CC is a somewhat constant-current source. V Offset is the voltage offset of cumulative errors. Note that this ...

A ruggedized design not only enables the Model ST131 tooperate over a temperature range of –40°C to +80°C, but also provideselectrical noise immunity and surge protection. CE and UL/cUL Class 1, ...

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 ...

PRS Series RTD sensors have a temperature range of -58 °F to 392 °F and are designed for sanitary or clean-in-place (CIP) applications in food/beverage, dairy and biopharmaceutical facilities. They’re ...

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 ...

MPFA000024 is a head-type RTD sensor from Multicomp Pro that’s designed for Class A accurate measurements across a -50 °C to 250 °C temperature range. This sensor runs at 100 ohms, and is reported to ...

The sensor measures temperatures from -40 to 160 °C (-40 to 320 °F), works in pressures up to 725 psi, and provides a 4-20 mA output with HART. >>For more information on this product, click here ...

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