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.

PT100 Resistance

Measures the resistance of a platinum element. The resistance is then converted to temperature.

Product Features 

  • Accurate and robust with good long-term stability
  • Suitable for manual or remote reading and datalogging
  • Strong, screened and flexible cable

Product Benefits

  • Choice of temperature sensors to suit project and site requirements
  • Low cost option
  • Cable lengths can be up to 100m or 1000m, dependent on choice of sensor

Resistance Sensor: The sensor is placed in the medium to be monitored. A platinum element changes resistance with temperature and the resulting resistance change is converted to temperature using a handheld readout or data acquisition system.


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.
