Many of Riedon’s Wirewound products are available in special high Temperature Coefficients of Resis- tance (TCR) ideal for use in temperature sensing applications. Special TCRs are most commonly used with our precision wirewound resistors series (100, SM, PC) but may also be used in our power series (UT, UB) and our surface mount series (S). Custom packages can also be designed to meet your specifi- cations. Please inquire directly if you have a unique application and our applications engineering depart- ment will assist you from start to finish.


Wirewound sensors provide for the most accurate temperature measurements over a wide range of tem- peratures and with the most flexibility as to TCR selected.


We provide high temperature elements with all-welded construction for use in high stress and vibration applications. Wirewound sensors provide users with the stability, uniformity, and repeatability needed for critical performance criteria.


Common Applications:

HVAC controls, Industrial Temp Probes, Aerospace Sensors, Compensation Resistor, Process Control


The table below displays commonly used wires in high TCR applications. Since Riedon stocks these wires, lead times are short when selecting a high TCR wire. Selection of TCR is not limited to what is listed in the table - other TCRs are attainable by using different manufacturing techniques. Please inquire directly if you have a TCR requirement that is not listed in the table.
