TPSYS02
PC CONTROLLED THERMAL CONDUCTIVITY
MEASUREMENT SYSTEM
TPSYS02 is a system for the
measurement of thermal conductivity using TP02 or TP08 Non-Steady-State Probes (NSSP).
The system is designed for high accuracy measurements. It is particularly suitable for analysis of soils, thermal backfill materials,
sediments, foodstuff, powders, sludges, paints and glues.

The main components of TPSYS02 are the
TP02 (or its smaller equivalent, type TP08) Non-Steady-State Probe, the MCU
Measurement and Control Unit and software. TP02 and TP08 are designed for
measuring in media in the thermal conductivity, λ, range of 0.1 to 6 W/m.K. The
measurement principle is that of a NSSP or Transient Line Source. For details on
TP02 or TP08, see the separate brochures. The MCU takes care of the measurement
and control process. It is recommended to perform measurements with TPSYS02 in a
laboratory environment. A special "field configuration" is available for
stand-alone measurements.
TPSYS02 is operated in conjunction with
a PC or laptop (field configuration: via Keyboard Display). The software arranges
communication with the MCU. It serves to give instructions like starting the
measurement and allows viewing the measurement results. Unique is that the
measurement is extremely fast (several minutes only), absolute and independent
of sample size.

configuration in the lab. Needle type TP02 or
TP08 (1),PC (2) (PC not included), Sample (3), MCU (4), RS232 (5), Adapter
suitable for both 220 and 110 VAC (6). The MCU runs on 12 VDC, so with a battery
power supply and laptop it can also be used in the field.

the MCU (4), the Keyboard Display (2) can be used for stand-alone operation. After the
field experiments TPSYS02 can be connected to a PC and the complete data can be
retrieved from the MCU.
MORE INFORMATION / OPTIONS
Alternative designs:
Hukseflux is specialised in NSSP design. Alternative models,
for instance for field use, are available at Hukseflux.
For use in soils, it is suggested to also consult the
brochures of the more robust but less accurate systems FTN, MTN and TNS.
STANDARDS
The
measurement with MTN complies with the IEEE Guide for Soil Thermal Resistivity
Measurements (IEEE Standard 442-1981) as well as with ASTM D 5334-92 Standard
Test Method for Determination of Thermal Conductivity of Soil and Soft Rock.
TPSYS is suitable for use by ISO certified laboratories.
NEW!
For high accuracy calibration CRC
Calibration Reference Cylinders are available.
For insertion into hard media GT Series
Guiding tubes can be applied.
