Pressure Transmitter

Pressure sensors are critical components in industrial automation and various monitoring systems. Their accuracy and reliability directly affect the efficiency and safety of entire systems. Therefore, conducting accurate testing to evaluate their performance and condition is an essential step in ensuring system stability. This article will provide a detailed guide on testing pressure sensors, including […]

In pressure and level transmitter selection, diaphragm material plays a critical role, especially under extreme working conditions such as strong corrosion, high temperature, and cryogenic environments. Proper material selection ensures the reliability, accuracy, and longevity of the transmitter. 1. Diaphragm Material Selection for Strong Acid and Strong Alkali Environments 1.1 Strong Acid Environments (e.g., Sulfuric

In industrial applications, differential pressure transmitters are widely used for liquid level measurement in tanks and containers. During installation and configuration, terms like “negative migration” and “positive migration” often come up. These adjustments are crucial for ensuring accurate measurement. This article explores why negative and positive migration are necessary, how to calculate the migration amount,

1. Definition of Accuracy and Range Accuracy Class:Refers to the maximum permissible error as a percentage of the full-scale range.For example, a gauge with an accuracy of Class 1.0 means the measurement error is within ±1% of its full range. Measurement Range:Indicates the span between the minimum and maximum measurable pressure.E.g., a 0–10 MPa gauge

A Barometric Pressure Transmitter is an instrument designed to measure atmospheric pressure and convert it into a standardized electrical signal for monitoring or control purposes. As a key member of the pressure transmitter family, it holds significant importance in various industrial, scientific, and environmental applications due to its accuracy, reliability, and versatility. 1. Laboratory Standard

In the field of industrial instrumentation, pressure transmitters often require adjustments to their measurement range, especially when installed in varying physical positions relative to the pressure tapping point. This process is known as zero migration, which includes zero elevation, zero suppression, and no migration. Understanding and properly adjusting for these conditions is essential to ensure

Pressure gauges are widely used in industrial settings, laboratories, and even daily life. Despite their ubiquity and critical role in safety, their calibration schedules are often overlooked. Some may think, “As long as the needle moves, it’s fine.” However, nothing could be further from the truth. Without regular calibration, a pressure gauge can accumulate measurement

Pressure transmitters are critical components in industrial measurement systems, and their stability over time directly impacts process control and data accuracy. Among the common performance concerns are two types of signal drift: initial drift and long-term drift. While both involve deviations in output signal, they occur under different conditions and have distinct causes and implications.

In modern technology and industrial applications, pressure sensors play a crucial role as essential measurement tools. Among them, gauge pressure sensors, differential pressure sensors, and absolute pressure sensors stand out as the three core categories in the field of pressure measurement. This article delves deeply into the definitions, working principles, measurement objects, application scenarios, and

In our world, pressure is ever-present, and differential pressure sensors act like silent “watchdogs,” constantly monitoring pressure differences in various systems. From industrial production to daily life, these sensors are omnipresent, providing crucial support to ensure smooth operation in countless applications. 1.
