Shinko temperature sensors come in two main lines: type K thermocouples (TC-E) for high temperatures up to about 1,200 °C and Pt100 RTDs (TC-R) for accurate measurement in the low-to-medium range. ISE supplies Shinko temperature sensors in the lengths and diameters you need, with thermowells and signal converters, in line with European standards EN 60584-1 and EN 60751.

Shinko Pt100 RTD (TC-R)
| Parameter | Value |
|---|---|
| Model | TC-R |
| Element | Pt100 (100 Ω at 0 °C, α = 0.00385) |

Type K thermocouple or Pt100?
| Criterion | Type K | Pt100 |
|---|---|---|
| Principle | Seebeck voltage at the junction | Platinum resistance changes with temperature |
| Range | Up to about 1,200 °C | Typically −50 … 500 °C |
| Accuracy | Lower (±2.5 °C class 2) | High (±0.35 °C at 100 °C, class A) |
| Robustness | High temperature, vibration-resistant | Long-term stable, avoid shocks |
| Applications | Furnaces, kilns, dryers, flue gas, burners | Steam, hot oil, food, HVAC |
Pt100 tolerance by class (JUMO – Pt100 accuracy class): class A ±0.15 °C at 0 °C and ±0.35 °C at 100 °C; class B ±0.3 °C at 0 °C and ±0.8 °C at 100 °C.
Wiring temperature sensors correctly
- 2-wire Pt100: lead resistance adds to the reading – 1 Ω of lead gives about 2.6 °C error.
- 3-wire Pt100: compensates lead resistance; the industrial standard choice.
- 4-wire Pt100: most accurate; or use a 4–20 mA head transmitter for long cable runs.
- Type K: use the correct type K extension cable (EN 60584-3, green), correct polarity, and cold-junction compensation at the instrument.

- Plastic injection, moulds, food processing, HVAC.
FAQ
Can Shinko sensors replace other brands?
Yes, if element type (K or Pt100), accuracy class, dimensions and connections match. ISE helps cross-check specifications.
Why does a type K thermocouple drift at high temperature?
Ageing, EMF drift and sheath oxidation. Check and calibrate periodically and select an Inconel sheath of suitable diameter for the working temperature.
