Heraeus M Series Pt RTD Sensor Elements

Heraeus M-series platinum temperature sensors have the widest range of element sizes, R0 resistance values and accuracies.  This makes them a very versatile range and subsequently our best-selling series.

The smallest Heraeus M213 version is only 1.25mm wide by 1.7mm long yet we can still offer a Pt1000 version to class B (F0.3) accuracy.  The largest Heraeus M1020 series (1.9mm wide x 9.5mm long) has the widest range of resistance values whereas the Heraeus M422 series (2.1mm wide by 3.9mm long) also offers all three main Pt100, Pt500 and Pt1000 values to 1/3DIN accuracy if required.

1/3DIN (or F0.3 or class 1/3B) accuracy is also available in the smaller Heraeus M222 series (2.1mm wide x 2.3mm long) making ±0.10°C at 0°C possible in a very neat small RTD package.  The platinum-coated nickel wires also makes them easy to solder but they can also be welded, brazed or crimped.
