It was a revelation when I first learned that people could own air compressors. That experience, as well as my experiences of learning that people can own power washers, power tools or power anything, really, was the impetus for the restructuring of

Imagine the following situation. You are the pilot of a commercial airliner on a sold-out flight. You are carefully monitoring all of the instrumentation in the cockpit, and so far the flight is going smoothly. Unbeknownst to you, though, a piece of

When Adjustable Pressure Switches are a Good Idea (And When They Aren’t)

micheals — Tue, 24 Jan 2012 21:34:20 +0000

Pressure switches are valued because of the control they give their operators over the systems in which they’re included. In an air compressor, for example, the pressure switch is triggered when the pressure within an enclosure reaches a certain re

How High Pressure Switches Can be Used

There are many different kinds of pressure switches. This is because there are many different kinds of applications in which the measurement and regulation of pressure is necessary. Consider the following examples. Suppose that you work for a company

Digital Pressure Gauges vs. Analogue Pressure Gauges

micheals — Tue, 27 Dec 2011 21:01:45 +0000

Every pressure gauge serves essentially the same purpose: to convert a reading of pressure in an enclosed system into a signal that can be read by humans or a control system. The differences between pressure switches are found in other areas. They ar

Understanding Pressure Transduction

Before a pressure switch can send a signal to monitoring or control equipment, it must first generate an electrical signal to send to that equipment. The generation, strength and type of signal are expressions of the kind of pressure to which the pre

Yesterday, I took my 1997 Ford Escort in for an oil change. I know very little about cars, so I almost never undertake even the most basic maintenance tasks by myself. Here’s what I do know about my car. I know

Pressure Switches in Emergency Shutdown Systems
