Pressure Transmitter

Pressure transmitter accuracy is a key indicator of measurement reliability. However, the belief that “higher accuracy is always better” is not universally applicable. In industrial practice, the selection of a pressure transmitter should be based on actual application requirements, rather than pursuing the highest specification available. 1. Understanding Accuracy in Pressure Transmitters Accuracy defines how […]

This guide summarizes key field requirements for the installation and inspection of pressure instruments, following common industrial standards. 1. Installation Requirements Vertical Mounting: Vibration-resistant pressure gauges must be installed in a vertical orientation. Support Height: For pressure or differential pressure transmitters, the mounting pillar should be 1.2 meters tall. Capillary Tubes: Capillaries should be bundled

In various industrial and scientific contexts, understanding the distinction between ambient temperature and process temperature is crucial. These two terms refer to different temperature measurements, each playing a distinct role in the operation, performance, and safety of equipment and processes. Here’s a detailed breakdown of the differences and their respective importance. What is Ambient Temperature?

Single flange pressure transmitters are widely used for direct pressure or level measurement in tanks and pipelines.

Transmitters are widely used in industrial automation systems for measuring process variables such as pressure, temperature, and flow. However, during operation, transmitter failures can occur due to various reasons, posing challenges to maintenance personnel. Quickly and accurately identifying the root cause is critical for minimizing downtime. Based on years of field experience, engineers at Xingyi

A glycerin-filled pressure gauge—also referred to as an oil-filled pressure gauge—is a type of mechanical pressure measuring device that enhances performance by filling the casing with damping liquid such as glycerin or silicone oil. It is widely used in industrial applications where vibration, pulsation, or corrosive conditions may affect the accuracy and lifespan of standard

1. Fundamental Principle Differential pressure (DP) flow meters operate on the throttling principle, derived from the Bernoulli equation. They calculate flow rate by measuring the static pressure difference generated as the fluid passes through a restriction (such as an orifice plate or venturi tube), and combining it with known physical parameters. 1.1 Working Principle When
