The TH is a temperature sensor used to monitor temperature in rock, concrete, soil or grout. Applications include monitoring of dams, bridges, buildings and tunnel linings. It also provides a reliable method to monitor the influence of temperature on instruments. The simple and rugged design allows direct embedment in fresh concrete or grouting in boreholes. Its sensing element can either consist of 3kΩ chip thermistor, a platinum resistor or a thermocouple. |
