TRSYS01
High
accuracy thermal resistance measurement system with 2 measurement locations
TRSYS01 is a
measurement system for analysis of thermal resistance and thermal transmittance
of building elements by in-situ measurement. It can be used for measurements
according to ISO 9869 and ASTM C1155 / C1046 standards. In its standard
configuration the system is equipped with two heat flux sensors as well as two
pairs of matched thermocouples for differential temperature measurements.
TRSYS01 consists of MCU Measurement and Control Unit (1), an adapter for power (2), 2
pairs of matched thermocouples (4), and 2 heat flux plates of type HFP01 (5). MCU measures
and stores data. Readout is performed by connecting temporarily to a PC (3) (not
included). Software for readout is included.

INTRODUCTION
The in-situ measurement of thermal
resistance, thermal transmittance or U-Values of buildings is often applied in
studies of building elements.
The thermal resistance, TR, measurement
is based on simultaneous measurement of time averaged heat flux
F
(using a heat flux sensor) and differential temperature, ΔT, (two temperature
sensors).
TR = ΔT /
F
The ISO and ASTM standards on the
subject comment on applicability of the method, on installation and on data
analysis.
The TRSYS consists of high accuracy
electronics (measurement accuracy up to 1 microvolts) as well as matched
thermocouple pairs to make a differential temperature measurement with a total
accuracy of better than 0.1 degrees C.
It also includes HFP01 heat flux plates. HFP01 is the world’s most
popular sensor for heat flux measurement through building envelopes.
