Temperature transmitter

In chemical plants, the installation of temperature measuring instruments such as thermometers and temperature transmitters often requires careful consideration of the thermometer sheath (TW). Since the sheath comes into direct contact with the medium, the material selection must align with the characteristics of the medium—be it corrosive, flammable, or explosive—to ensure stable operation and meet […]

Resistance Temperature Detectors (RTDs) are widely used temperature sensors that measure temperature by correlating the resistance of the sensor material (usually platinum) to temperature changes. RTDs are commonly classified into accuracy classes, with Class A and Class B being the most frequently used. These classifications, based on standards such as IEC 60751 and ISO 17025,

Platinum Resistance Temperature Detectors (RTDs) are widely recognized for their accuracy, stability, and linear temperature-resistance relationship. RTDs utilize platinum as their sensing element, leveraging the material’s predictable changes in resistance in response to temperature variations. The design of an RTD sensor requires careful attention to multiple factors, including the sensing element, insulation, lead design, housing,

Temperature measurement is crucial across various industries, from manufacturing to healthcare, to ensure safe and efficient operations. Industrial thermometers come in different types, each suited to specific environments and applications. These thermometers vary in design, materials, and measurement methods. Below is a detailed exploration of the most commonly used industrial thermometers and their applications. 1.

Common methods for measuring humidity include: dynamic methods (dual pressure method, dual temperature method, and split-flow method), static methods (saturated salt method and sulfuric acid method), dew point method, dry and wet bulb method, and electronic sensor method. Method 1: Dynamic Method The dual pressure method and dual temperature method are based on the principles

Thermocouples are widely used temperature sensors that convert thermal energy into electrical energy through the Seebeck effect. They are known for their durability, wide temperature range, and ability to function in harsh environments. Among the many types of thermocouples, the K, N, J, E, and T types are the most commonly used in industrial and

An integrated temperature transmitter plays a critical role in converting temperature signals from sensors (like thermocouples or RTDs) into standardized electrical signals (commonly 4-20 mA). Proper wiring is essential to ensure accurate data transmission and long-term reliability. Below is a detailed guide on wiring an integrated temperature transmitter. 1. Preparation Before Wiring Before starting the

1. Thermal resistance thermometer Common faults of industrial thermal resistors are open circuit and short circuit. Generally, open circuit is more common, which is caused by the thin wire of thermal resistor. Open circuit and short circuit are easy to judge. You can use the “×1Ω” position of the multimeter. If the measured resistance is

Thermocouples (T/Cs) and resistance temperature detectors (RTDs) are widely used in various industries to measure temperature. While they both serve the same purpose, their underlying technology, performance, and applications vary significantly. Here’s a detailed breakdown of the differences between thermocouples and RTDs: 1. Operating Principle Thermocouples: Thermocouples operate based on the Seebeck effect, where a
