Thermocouples and RTDs
Thermocouples and RTDs are the most common temperature sensors in industrial processes. They provide accurate readings for control systems, recorders and safety interlocks.
Sensor Types
- Thermocouples – types J, K, T, E, N, R and S for wide temperature ranges
- RTDs – Pt100 and Pt1000 for high accuracy
- Mineral insulated sensors – rugged and bendable
- Head-mount assemblies – with transmitters and terminal blocks
- Surface and probe sensors – specialized mounting
Choosing a Sensor
Thermocouples handle higher temperatures, while RTDs offer better accuracy and stability. Specify sheath material, length, diameter and connection. Use matching extension wire.
Centro supplies thermocouples and RTDs for temperature measurement.
