Temperature transmitter

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,

Selecting the right temperature transmitter is critical to ensuring accurate and reliable temperature measurements in various industrial and commercial applications. This guide provides a detailed overview of the parameters to consider and the steps involved in the selection process. 1. Key Parameters for Selection 1.1 Measurement Range Choose a transmitter with a measurement range that

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,
