Selection of Common Anti-corrosive Material for Instrument Manufacturing

In process measurement, one of the fundamental response to corrosive measuring medium is use appropriate material resistant to the corrosion for instrument’s wetted-part, sensing diaphragm or its coating, electronic case or other required parts and fittings. PTFE: PTFE(Polytetrafluoroethylene) is... Read More

Risks of Corrosive Media in Process Measurement

Corrosive media are substances that can cause damage or degradation to surface and structure via chemical reactions. In the context of measurement instrument, corrosive media usually involve liquids or gases that may react chemically with materials of the instrument over time, adversely affecting... Read More

Bimetallic Thermometer Preliminary Understanding

Bimetallic thermometers use a bimetallic strip to convert temperature changes into mechanical displacement. The core operating idea is based on the expansion of metals who changes their volume in response to temperature fluctuations. Bimetallic strips are composed of two thin strips of different ...

Process Control Application among Storage & Transportation in Oil & Gas

Storage vessels and pipelines are key equipment for oil and gas storage and transportation, connecting all stages of the industry. From extraction to delivery to end users, petroleum products undergo multiple processes of storage, transportation and loading & unloading. Changes in pressure, l... Read More

Usage of Differential Pressure Transmitter in Cleanroom Application

Typically speaking, a cleanroom is constructed to establish a environment where containment of pollutant particles is controlled to low level. Cleanroom is extensively applicable in every industrial processes that impact of small particles needs to be eradicated, such as medical device, biotech, ... Read More

Introduction to Diaphragm Seal Connection for Transmitter

The diaphragm seal is a method of installation used to protect instruments from harsh process conditions. It acts as a mechanical isolator between process and instrument. The protection method is generally used with pressure and DP transmitters that connects them to the process. Diaphragm seals a... Read More

Fundamental Pressure Definition and Common Pressure Units

Pressure is the amount of force exerted perpendicular to the surface of an object, per unit area. That is, P = F/A, from which it is obvious that smaller area of stress or stronger force reinforce  applied pressure. Liquid/Fluid and gas can also apply pressure as well as solid surface. Hydrostati... Read More

WangYuan Reliable and Safe Pressure Measurement in Diverse Environments

Given the critical role of pressure in the process control of all kinds of industries, precise and reliable instrumental integration is paramount. Without proper coordination of measuring device, connection components and field conditions, entire section in a factory might be unable to commence o... Read More

Heat Sink Application in Instrumentation

Heat sinks are often used in electronic devices to dissipate heat energy away, cooling down the devices to moderate temperature. Heat sink fins are made of heat conductive metals and applied on high temperature device absorbing its heat energy and then emit to ambience via radiation and convectio... Read More

Accessories for Differential Pressure Transmitter

In normal operations, several accessories are commonly used to assist differential pressure transmitters in functioning properly. One of the vital accessory is valve manifold. The purpose of its application is to protect the sensor from single-side over pressuring damage and isolate the transmitt... Read More
