Thermocouple Temperature Sensor

The Thermocouple Temperature Sensor is used for measuring temperature in concrete, soil and rock.

Temperature sensors are used to monitor temperature in concrete, rock and soil.

They are ideal for monitoring temperature during concrete curing, for evaluating seasonal variations within ground and structures and to interpret temperature-related stress and volume changes in dams.

Thermocouple – comprises of two dissimilar conductors joined at one end to form a hot junction which produces a voltage. As the junction is heated or cooled the voltage changes and is converted to return the temperature.

Thermocouple Sensor: The sensor is sealed against corrosion and placed in the medium. The thermocouple voltage is generated from two dissimilar conductors being joined to form a hot junction. This hot junction creates a voltage and, as the junction is heated or cooled, the voltage will change. The result will be proportional to the temperature at the installed location – a readout or data acquisition system can be used to read the voltage and convert it to temperature.


Temperature sensors are used for measuring temperature in concrete, soil and rock including:

Monitoring temperature during concrete curing
Soil and rock temperatures adjacent to ground freezing operations and liquid gas storage tanks
Measurements of water temperatures in reservoirs and boreholes
Monitoring seasonal variations within the ground and structures
Interpretation of temperature-related stress and volume changes in mass concrete structures including dams
Air temperature measurements on structure surfaces
Determination of critical moment for injecting joints within mass concrete structures
Interpretation of temperature effects on other installed instruments.
