Measuring range is the range of the measured variable that the instrument measures with the specified accuracy.
Temperature is a key parameter that must be controlled in industrial production, since it directly affects product quality, equipment and personal safety in industrial production. We should not blindly value the high-precision, large-scale and high-level automation, but should combine the specific process of industrial production and comprehensively consider the temperature sensors, including the actual conditions of the medium being measured and the economic factors. We should follow the principle of testing instruments, and the measured temperature should be greater than the upper and lower temperature limits of the medium being measured. When the measurement accuracy meets the requirements of production technology and the application method enables surveyor to observe and facilitates daily maintenance and care, we should choose the test instrument with reasonable price.
Since the temperature sensor serves as a non-standard product, it is required to communicate fully with the customer before the sale.
Generally, open circuit is quite common because of the thin wire of thermal resistor. It is easy to confirm open circuit and short circuit using multimeter Q "x1", for example, if the measured value is less than RO, there may be a short circuit
