Bimetal thermometers are widely used in various industries due to their simple design, reliability, and cost-effectiveness. They play a crucial role in accurately measuring temperature in industrial, chemical, and even residential applications. However, improper use or exposure to adverse conditions can lead to their damage or failure. Understanding the causes of such damage is essential

Temperature transmitters convert signals from temperature sensors such as thermocouples and RTDs into standard analog signals (e.g., 4–20 mA or 0–10 V) through processing circuits including voltage regulation, filtering, amplification, linearization, V/I conversion, and protection. They are widely used in industrial process control for accurate temperature measurement. 1. Overview and Structure A typical temperature transmitter

In industrial environments where ultra-precise temperature control is essential—such as semiconductor manufacturing, precision material processing, and high-end laboratory equipment—relying solely on a general-purpose PLC is often insufficient. While a PLC can technically perform temperature control, it falls short in many aspects when compared to dedicated temperature controllers. This article explores the key reasons behind this

Bimetallic thermometers are widely used in industrial environments due to their simple structure, reliability, and independence from external power sources. However, they can suffer from various types of damage over time, which may lead to inaccurate readings or complete failure. This article outlines five common categories of damage and provides detailed explanations and preventive measures
