Probes Transmitters & 2300 Series – April 2019

RTD Probes

RTDs are by far the most accurate temperature probe type available (±0.15°C), with a typical temperature range of -200~300°C.
The most commonly used RTD is the Pt100, so named due to the fact that the element material is usually Platinum (chemical symbol ‘Pt’), and because at a temperature of 0°C it provides an electrical resistance of 100ohms.

Thermocouple Probes

Without getting too technical, thermocouples are very simple devices that operate via the principle ‘thermoelectric effect’; two different alloys that produce a voltage proportional to a temperature difference.
Thermocouples with ‘Compression Fitting MTH-LH’ tend to be popular because they are inexpensive, interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures; -185~2,320°C.

However, we recommend RTD’s for more accurate temperature readings below 500°C.
