Diaphragm seals protect expensive measuring instruments from direct contact with potentially dangerous process media. Adding a diaphragm seal to a pressure gauge or sensor offers protection from corrosive media and mitigates the impact of both high- and …

Getting a Grip on Dual-Purpose Capillary Lines
Chi-Che MaAn instrument capillary line can serve a dual purpose. First, capillary lines, or tubes, are a convenient method for separating a pressure instrument such as a gauge or transmitter from the process connection so the reading can be taken at a more accessible location. …
How to Choose the Right Fill Fluid for Your Diaphragm Seal
Chi-Che MaA diaphragm seal is designed to protect expensive instruments. It operates by transferring the pressure effect of a process media through a membrane-like seal to a fill fluid that then transfers the resulting pressure wave to a pressure gauge or sensor at the head of …
Extreme Process Temperatures Need Diaphragm Seals with Cooling Elements
Chi-Che MaExtreme process temperatures need diaphragm seals with cooling elements, heat will degrade almost any mechanical or electronic device over time. Similarly, extreme process temperatures have been shown to dramatically reduce the functional lifetimes of sensitive …
Understanding Why Some Pressure Sensors Fail, and What to Do about It
Robert LukatElectronic pressure sensors can stop working for a variety of reasons. Understanding those reasons is a key step in preventing future failures. A pressure sensor plays a key role in the instrumentation of machinery and processes. When sensors fail, the process …
