Temperature transmitter

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

1. What Is a Fiber Optic Temperature Sensor? A fiber optic temperature sensor is a temperature measurement device that uses optical fibers as the sensing medium. Unlike traditional electrical temperature sensors (e.g., thermocouples, RTDs), fiber optic sensors offer significant advantages such as immunity to electromagnetic interference (EMI), high-temperature resistance, compact size, and distributed measurement capability.

1. Overview The detachable cap bimetallic thermometer, also known as a bayonet-type bimetallic thermometer or removable cap bimetallic thermometer, is a widely used temperature measurement device in industrial applications. It is designed to measure the temperature of liquids, steam, and gaseous media within the range of -80℃ to +500℃. This thermometer is commonly utilized in

Introduction Temperature sensors are among the most commonly used detection devices in industrial and environmental monitoring systems. Platinum resistance temperature detectors (RTDs), such as the Pt100, are known for their high measurement accuracy and stable performance. These sensors are widely applied not only for process temperature monitoring but also as reference standards in calibration systems.

Bimetal thermometers are widely used mechanical temperature measurement devices known for their robust design, wide temperature range, and ability to function without external power supply. Based on the principle of thermal expansion, they convert temperature changes into mechanical displacement via bimetallic strips, which drive a pointer on a dial for direct reading. Due to their

Introduction Temperature sensors are instruments that convert temperature variables into standardized output signals, widely used in industrial processes for temperature monitoring and control. Despite their reliability, users—whether engineers, technicians, or maintenance personnel—often encounter various issues during field applications. This article introduces the most common causes of temperature sensor failures and provides practical guidance for troubleshooting
