100-Channel Thermocouple Referencing System
Available in 19" Rack Mount Chassis
Commonly Use in Aircraft and Power Plants to Optimize Thermocouple Measurements

• Thermocouple Referencing to ISO9000 at 0°C in Ambient Temperatures up to 65°C or elevated reference temperatures between 45°C and 70°C
• References Up To 100 Thermocouples
• Pre-wired Thermocouples, Compact Design
• The TRURAC Combines Two TRU 100 in a 19” Rack-Mount Enclosure for the Referencing of Up To 200 Thermocouples

The TRU 100 (Temperature Reference Unit) supplies a stable and accurate 0°C or elevated Reference Temperatures between 45°C and 70°C.

It is a self-contained all solid state unit using peltier technology which provides maintenance free operation. The TRU 100 features rapid cool down from high ambient temperatures and is stable within 10 minutes from switch on.

An alarm will be activated should the reference temperatures deviate by more than the user definable span. Thermocouple Reference Junctions are located in a reference block and connected to their marked input and output terminals in an isothermal enclosure. The uniform temperature throughout the enclosure ensures that no thermoelectric EMFs are generated at the terminals.

One advantage of the TRU100 is that the user need not be concerned with the supply and installation of reference junctions since it is only necessary to connect the thermocouple compensation cables to the input terminals and the measuring instrument to the output terminals of the TRU100.
