Anothermethod is to calculate the temperature. For a platinum RTD, the Callendar-Van Dusen equation describes the relationship between resistance and temperature as: R(t) is the RTD resistance t is ...

The data are 15-bit ratios between the reference resistor (in my case 427 Ω) and the RTD probe. As the temperature of the probe increases, its resistance increases in a nearly linear fashion.

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, ...

Omega’s new DTG-RTD100 Series features a large backlit display with 25mm (1”) digits that can be read as far as 10.7 m (35’) away. Reading features include, process, Min, Max, Alarm condition and ...

Arguably, this advice applies to the circuit design used in many RTD sensors that quietly and efficiently measure temperature in industrial manufacturing facilities worldwide. However, to meet the ...

ELECTRONICS: Omega’s DTG-RTD100 Digital Thermometer Series features a large backlit display with 25mm (1 inch) digits that can be read as far as 10.7 m (35 feet) away. Reading features include, ...
