Type K Thermocouples

Thermocouples consist of two wires of different types of metal joined together in the end. This junction is where the temperature is measured (the tip of the thermocouple). When the junction is heated or cooled, a tiny current is created; This is therefore used to calculate the temperature inside the concrete.

Type K thermocouples are simple to use, versatile, widely available, and cost-effective temperature sensors – ideal for concrete monitoring.

In general, temperature sensors should be positioned at critical locations such as the core, surfaces, outer faces, and corners. The typical positions are often: Core (hot), surface (cold), close to the formwork, and ambient air temperature.

For larger projects, the monitoring positions are often described in a thermal control plan defined by consulting engineers or concrete technologists.

±1.5 °C (±2.7 °F)

-25 to 125 °C (-13 to 257 °F)

You can use type K thermocouples with the Maturix Transmitters (Gaia 200 / Orbit K).

We offer ready-to-use sensors in 1m / 3m / 5m / 10m. We also offer 100m cable rolls and connectors, so you can cut and assemble the cables in your desired lengths.

Yes, as long as they are type K.

They are accurate and of high quality. The cable sheath is made of Teflon, which makes it more resistant to breaks and damage. This also provides a perfect combination of flexibility and stiffness for easy installation.

Yes. Remove the insulation at the end of the cable, twist the two conductors tightly around each other, and put some heat-shrink tubing around to avoid wrong readings.

Heat-shrink tubing. This protects the exposed thermocouple wires and reduces reading errors.

No. The thermocouple must be connected to a transmitter at all times during monitoring.
