Temperature transmitter

Introduction A resistance temperature detector (RTD) is a sensor that measures temperature based on the principle that its electrical resistance changes with temperature. Specifically, it utilizes the property of metal conductors or semiconductors where the resistance value varies with temperature. By measuring the change in resistance, the temperature can be calculated. RTDs are among the […]

Introduction Temperature control is a critical factor in the chlor-alkali and polyethylene (PE) industries, as it directly influences production efficiency, product quality, and equipment longevity. Accurate temperature measurement ensures optimal process conditions, minimizes energy consumption, and enhances safety in both industries. This article explores the various applications of temperature instruments in these sectors, focusing on

A temperature sensor (temperature transducer) is a device that detects temperature changes and converts them into a usable output signal. These sensors are essential components in temperature measurement instruments. Temperature sensors are widely used in industrial processes, medical equipment, environmental monitoring, and more. There are several common types of temperature sensors, each with unique characteristics

In the era of smart technology, temperature sensors serve as critical components in the fields of the Internet of Things (IoT) and industrial automation. These sensors continuously monitor environmental changes, converting temperature data into electrical signals or other identifiable forms. This capability provides invaluable support for system control, data analysis, and predictive modeling. This article

Sometimes, users confuse pressure transmitters and temperature transmitters. Although they look similar, there are still big differences in performance and structure. The following editor will introduce the difference between pressure transmitters and temperature transmitters in detail. 1. Definition – Pressure transmitter: a device used to measure the pressure of liquid, gas or steam and convert

Bimetal thermometers are widely used across various industrial and laboratory environments due to their durability, accuracy, and reliability in temperature measurement. However, the length of the thermometer probe is a critical factor influencing both measurement precision and operational convenience. Selecting the correct probe length ensures accurate readings, operational efficiency, and safety. 1. Importance of Probe

Thermocouples are widely used in various industries for temperature measurement due to their simplicity, reliability, and wide temperature range. However, their practical use often raises technical questions. This article addresses some of the most frequently encountered issues and provides solutions to help ensure accurate and stable temperature measurements. 1. Why is the thermocouple output unstable?

In industrial applications, temperature measurement is commonly carried out using thermometers or temperature sensors that are inserted into pipes, tanks, or other equipment. The insertion depth of these temperature sensors has a significant impact on the accuracy of the measurement. While the general guideline is to calculate the insertion depth based on the centerline of

In process control, the four fundamental parameters are flow rate, liquid level, pressure, and temperature. Among these, temperature control is widely regarded as the most challenging. This difficulty arises primarily from the mismatch between the high performance requirements of temperature control and the inherent characteristics of the controlled object. Flow Rate Control: The Simplest of

I. Temperature transmitter amplification effect Sensors and transmitters play a pivotal role in the field of instrumentation and industrial automation. Unlike sensors, transmitters can not only convert non-electrical quantities into measurable electrical quantities, but also generally have a certain amplification effect. Thermocouple temperature transmitters are generally composed of reference source, cold end compensation, amplifier unit,
