Take the guesswork out of the freeze-thaw cycle in pavement structures and sub-grades. MRC Temperature Probes provide the data for decisive management of roadway truck traffic and the minimization of pavement damage.
Other applications have included monitoring temperatures at specified depths in toxic fuel and waste sites, at housing construction sites where settlement due to permafrost exists, in conjunction with non-destructive testing, (NDT) and at airports (aprons) to detect maximum runway apron loads during freezethaw weather conditions.
MRC Probes were developed in 1982 as a direct result of the need for local agencies to monitor annual cyclic changes in pavement subgrade temperatures, specifically the freeze-thawphenomena. This information has provided data for decisive management of roadway load restrictions resulting in minimization of pavement damage caused by spring thaw cycles. Emphasis was placed on providing a rugged, easy to use system that would result in the direct sampling of temperatures below the pavement at specific critical depths.
TP101 Probes are designed to perform under severe environmental conditions over a range of -30 to +75 degrees C. These units use a thermistor as the temperature-sensing element. The standard probe is 1.1” in diameter and 48” long with 11 sensors located at 0, 3, 6, 9, 12, 18, 24, 30, 36, 42, and 48 inches. All probe assemblies are potted within a clear, schedule 40 PVC pipe, allowing for a completely encapsulated environment and ensuring a long installation life. The TP101 is accurate to ±0.1 Degrees C. |
