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, ...

Pt resistors exhibit high precision and linearity over a wide temperature range. Thus, this study explored Pt-based sensors on SiC substrates, incorporating an Al 2 O 3 intermediate layer.

These sensors have a range of up to 200 m against a target with 10% light reflectivity. The new M2 is a lower cost evolution of the M1 design that claims to provide some improvement in performance ...
