Pressure Transmitter

Pressure sensors are one of the most widely used types of sensors, finding applications in industries ranging from aerospace to medical devices. Traditional pressure sensors predominantly relied on mechanical structures, such as elastic elements that indicate pressure through deformation. However, these sensors were bulky, heavy, and lacked electrical output. With the advancement of semiconductor technology, […]

Pressure transmitters are critical measurement instruments in industrial automation, and their selection directly impacts measurement accuracy, stability, and device longevity. Given the complexity of operating conditions, a systematic approach is essential to ensure the appropriate selection of a pressure transmitter. This guide delves into key factors such as the properties of the measured medium, environmental

During the use of the transmitter, periodic draining is required, primarily to address the accumulation of dust, oil residue, and small particles in the pressure guide tube or pressure tap valve, which can occur when measuring with differential pressure transmitters and pressure transmitters. Failing to perform this maintenance can result in inaccurate measurement results. Steps

In industrial and laboratory settings, high-pressure gauges play a critical role in monitoring and maintaining safe operating conditions. These devices are essential for measuring system pressure accurately, but their usage also comes with inherent risks, especially in high-pressure environments. Therefore, installing protective covers and pressure relief devices on high-pressure gauges is not just a precautionary

A pressure gauge operates by using the elastic deformation of sensitive elements inside the gauge (such as Bourdon tubes, diaphragm capsules, or bellows). The pressure-induced deformation is transmitted to the pointer through the movement mechanism inside the gauge, causing the pointer to move and display the pressure. When selecting a pressure gauge, we can consider

Introduction to Pressure Transmitters Devices that can detect pressure values ​​and provide remote transmission signals are collectively called pressure transmitters. They are a common sensor in industrial automation process control, used to measure the pressure of gas or liquid, and convert this pressure value into a measurable and transmittable electrical signal. These electrical signals are

Selecting the appropriate diaphragm for a pressure transmitter is a critical step that directly influences the device’s measurement accuracy, stability, service life, and long-term reliability. Below are detailed guidelines to assist in the selection process: 1. Understand the Properties of the Measured Medium The characteristics of the medium to be measured play a significant role

Pressure sensors, as critical components in measurement and control systems, play an indispensable role in modern technology and industry. The accuracy grade of a pressure sensor is one of the most important indicators of its performance. This article delves into the concept of pressure sensor accuracy, providing detailed insights to help professionals make informed decisions

Pressure measurement is an essential part of many industrial and scientific processes. Depending on the type of pressure gauge, measurements are made relative to different reference points: absolute vacuum, atmospheric pressure, or a sealed reference chamber. The question arises: can an absolute pressure gauge with a range of 0–100 kPa be used to measure negative

Most transmitters have two types: with display and without display. Transmitters with display can display the measured value of the measured medium in real time at the site of use, which is convenient for observation and value detection. The types of transmitters with display will be slightly different in terms of appearance size, power supply
