Choosing a temperature sensor by range
| Type | Range | Application |
|---|---|---|
| Pt100 / Pt1000 (RTD) | −200 … 600 °C | High accuracy: water, steam, oil, food |
| Type K thermocouple | −40 … 1200 °C | Flue gas, furnaces, dryers |
| Type N thermocouple | −40 … 1200 °C | More stable than K at high temperature |
| Type S / R thermocouple | 0 … 1600 °C | Kilns, metallurgy |
| Infrared | Non-contact | Moving objects, hot surfaces |
| 4–20 mA transmitter | Per sensor | Long-distance transmission to PLC |
Temperature sensor standards
| Standard | Scope |
|---|---|
| EN 60751 | Pt100 tolerance classes AA, A, B, C |
| EN 60584-1/-3 | Thermocouple EMF tables, tolerances, colour codes |

FAQ
Pt100 or thermocouple?
Below 600 °C with high accuracy: Pt100. Higher temperatures or fast response: type K or N thermocouple.
Why use a thermowell?
It protects the probe from pressure, flow and corrosion and lets you replace the sensor without shutdown.
