PT100 Resistance Temperature Sensor

The Resistance Temperature Sensor is ideal for monitoring temperature during concrete curing, for evaluating seasonal variations within ground and structures, and for interpreting temperature-related stress and volume changes in dams. It measures the resistance of a platinum element and 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.
