NMTEDHR24018BC0 - Type R Thermocouple Element Type R thermocouples use platinum conductor for the negitive conductor and a platinum?rhodium alloy for positive conductor. R type Thermocouples are among the most stable, but have lower sensitivity than other types.
Type R Thermocoulpes generate approximately 10 ?V/?C.
R Type thermocouples are usually used only for high temperature measurements due to their high cost and low sensitivity.
Temperature range for R Type Thermocouples:
-58?F to 3214?F (-50?C to 1768?C)
