Description |
Purchase additional sensor assemblies to run multiple
channels concurrently.
|
The small sensor internally records time-stamped temperatures
at user defined intervals. Simply plug the sensor assembly into a PC USB port and
start the sensor to begin internal recording. When concrete is placed, insert the
brass thermowell into the concrete to a specified depth, then insert the sensor
assembly into the thermowell and cap the thermowell. At any concrete age, remove
the sensor assembly from the thermowell and download timestamps and temperatures
to a PC. (Or download readings on-site using a laptop). Internal sensor recording
may then be stopped, or the sensor may be placed back into service. At the end of
testing, the thermowell is abandoned and the sensor's internal recording is stopped.
The sensor is retained for future testing. The sensor has an internal battery that
is rated for 10 years.
All interaction
of the sensor with a PC is done using the supplied software. The software also calculates
the Time-Temperature Factor (TTF) and Equivelant Age at each temperature reading.
Additional sensor
assemblies may be purchased, so there is no limit to the amount of locations that
may be monitored at one time.
No interfacing hardware
is required to record or download temperature data, greatly reducing cost and risk
of theft or failure of on-site equipment.
