Thermistors provide accurate and reliable long-term temperature measurements and are used widely in the extremely harsh environments found within Geotechnical monitoring.
They are available in two types:
Probe – A single point sensor mounted within a PVC or stainless steel housing which is attached to a cable length.
The probe is designed for measuring surface temperature of steel, concrete structures and the temperature inside concrete.
String – A series of sensors mounted along a multi-core cable which provide a temperature profile and is manufactured to customer requirements in terms of the number and spacing of each sensor.
Readings can be made with a wide range of readout units which display the reading directly in engineering units (deg Celsius) or by an ohmmeter in combination with look-up tables. Readings can also be automated using an automatic data acquisition unit.
