Thermocouples

Bimetallic thermometers are widely used in industrial temperature measurement due to their simplicity, reliability, and independence from power supply. However, their accuracy and service life depend heavily on proper daily maintenance. This guide outlines a comprehensive maintenance strategy across four key dimensions: cleaning, inspection, calibration, and environmental protection. 1. Cleaning and Component Inspection 1.1 Surface […]

Thermocouples are widely used in industrial environments as reliable temperature sensors. However, due to harsh working conditions and system complexities, they can occasionally encounter faults that affect measurement accuracy. This guide outlines common symptoms of thermocouple failures—abnormally low or high temperature readings—and provides step-by-step troubleshooting methods. 🔧 Problem 1: Displaying Minimum Temperature When the temperature

When selecting a protective sheath for a thermocouple or RTD, it is crucial to consider several key factors to ensure the device’s accuracy, reliability, and longevity in various industrial environments. Here’s a detailed look at the primary selection criteria for thermocouple and RTD protective sheaths: 1. Material Selection The choice of material for the protective

Thermocouples are widely used temperature measurement devices in various industries due to their simplicity, durability, and wide temperature range. They operate on the principle of the Seebeck effect, where two dissimilar metals connected at two junctions generate a measurable electromotive force (EMF) related to temperature differences. The fundamental principles guiding thermocouple operation are summarized by
