Cable
Compensating conductor: 3 m
PVC-covered cable with a shield wire resisting 70°C
Note: 1. Based on characteristics of K-type thermocouple and radiation rate of 0.9.
2. The accuracy is given as the change in temperature from any reference temperature of the sensing object. For example, if the reference
temperature is 50°C, the accuracy at 55°C would be ±2% PV or ±2°C, whichever is larger and the accuracy at 60°C would be ±4% PV
or ±4°C, whichever is larger.
