I would like to ask what TR10 and TR40 mean in the PT100 model
PT100 is a common type of temperature sensor, representing a platinum resistance temperature sensor. TR10 and TR40 are different accuracy grades for this model. TR10 indicates that the accuracy class of the temperature sensor is Class A. At this temperature range, the maximum measurement error of the temperature sensor does not exceed ±(0.15+0.002*|t|)°C, where |t| represents the absolute value of the temperature, within the range from -200°C to +600°C. TR40 indicates that the accuracy class of the temperature sensor is Class B. At this temperature range, the maximum measurement error does not exceed ±(0.3+0.005*|t|)°C within the range of -200°C to +600°C. Therefore, TR10 and TR40 represent different accuracy levels for PT100 temperature sensors, with TR10 having higher accuracy. .
I wonder what product samples the owner is looking at? I only know that TR10 is the model of the modular thermometer produced by E+H Company, while TR40 is the model of the cable-type thermistor thermometer manufactured by WIKA Company.
