Core Principle: Temperature-related faults in electrical or industrial systems can be quickly located using the inherent resistance–temperature characteristics of NTC/PTC thermistors and the mV output characteristics of thermocouples.By performing three diagnostic steps—static resistance check, dynamic heating/cooling test, and loop continuity/voltage measurement—more than 90% of temperature-related failures can be accurately identified. 1. Identify the Sensor Type
Introduction Temperature is one of the most fundamental and widely measured parameters in industrial processes. Nearly 50% of all process control applications involve temperature monitoring, and accurate temperature measurement is essential for product quality, equipment safety, energy efficiency, and overall plant reliability. Because temperature cannot be sensed directly, it must be measured through the physical
