Q as is the case with the RTD used in the 284 of the RTD the following equation is used R R 1 AT BT Below R an additional term is added to the equation R R 1 AT BT C T 100 T In both of these equations R is the resistance of the RTD at 0 C and A B and C are the coefficients as defined by IEC751 through regression analysis or by using the Callendar van Dusen method Not all Arroyo Instruments temperature controllers support RTD operation Check with the factory for the recommended controller as high temperature operation typically requires a higher voltage than is normally available with the standard 5305 and 5310 controllers see Operating at High Temperatures below For the Arroyo Instruments controllers that support RTD sensors the default coefficients are not correct for this mount They must be changed to use the 0 00385 Q Q C curve which has the following coefficients A 3 9080x10 B 0 58019x10 C 4 2735x10 R 100 These coefficients can be changed in the Sensor menu or by selecting the appropriate 284 mount from the Mount menu setting 2 Wire versus 4 Wire Measurements One concern in using RTDs are their relatively low resistance typically 100Q at 0 C and small Q C Because of these two factors the resistance of the cable used to connect to the sensor can become a significant error in the sensor measurement Most Arroyo Instruments controllers offer two RTD meas
