PT100 Resistance Temperature Sensor

PT100 Resistance Temperature Sensor Overview

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

Operation

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.

Application

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.
