During the operation of transmitters, zero drift and temperature drift are common issues that affect their measurement accuracy. But what exactly causes these drifts, and how can they be addressed? Let’s explore. Causes of Zero Drift and Temperature Drift in Transmitters Intrinsic Component Asymmetry: The components used in the transmitter’s bridge circuit may have inherent

In industrial and daily temperature monitoring, axial and radial thermometers are two common types distinguished by the orientation of their dial head relative to the temperature sensing element. This difference significantly affects their installation and application scenarios. This article explores the differences across four key dimensions: working principle, structural characteristics, application scenarios, and selection guidelines.

1. Signal Amplification in Temperature Transmitters Temperature transmitters play a vital role in industrial automation by converting physical temperature signals into standardized electrical signals for monitoring and control. Unlike sensors that typically generate raw signals, transmitters integrate multiple functions such as signal amplification, cold-junction compensation, linearization, and current output conversion. 1.1 Thermocouple Temperature Transmitter A

Bimetallic thermometers are widely recognized for their high precision and reliability in industrial measurement. However, these instruments often face harsh environmental challenges during use, which may affect their performance and longevity. This is where stainless steel sleeves come into play as essential protective components. Let’s explore the key features, benefits, and maintenance tips for stainless

Introduction Temperature and humidity are critical physical parameters that significantly influence various aspects of daily life and industrial processes. Temperature and humidity sensors are devices that convert these physical quantities into electrical signals that are easy to measure and process. Most sensors in the market are designed to measure temperature and relative humidity, playing a

Resistance Temperature Detectors (RTDs) are widely used in industrial applications for accurate and stable temperature monitoring, especially within low to medium temperature ranges. This article provides a comprehensive overview of RTD working principles, materials, types, wiring methods, troubleshooting techniques, and installation guidelines. 1. Principle of RTD Temperature Measurement RTDs operate based on the principle that

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
