WebAccording to DIN 43760, there are 2 CLASSES of RTD’s while ASTM E - 1137 recognizes 2 GRADES. DIN 43760 class B = ± .12% @ 0°C DIN 43760 class A = ± .06% @ 0°C ASTM E-1137 grade A = ± .05% @ 0°C ASTM E-1137 grade B = ± .10% @ 0°C SELF-HEATING Since RTD’s are a resistor, they will produce heat when a current is passed through them. WebRTD Accuracy: Comparing Class A, B, AA, & 1/10B. In this video REOTEMP Instruments compares the accuracy of common RTD classes: Class A, Class B, Class AA, and Class 1/10B. This video also discusses the formula used to determine a RTD accuracy at a …
