Video: Bellows for Temperature Switching

August 4, 2017

Temperature switching is another common use for metal bellows. The bellows are typically attached to a fluid-filled capillary. Changes in temperature cause the fluid to expand or contract, causing the bellows to move and actuate a switch, a gauge, or a valve. Bellows are found across many industries and are used extensively in thermostats, self […]

Maximize Aneroid Performance

December 6, 2016

Altitude-sensing aneroids play a crucial role in flight systems. But keep in mind that the aneroid will only be as good as the metal bellows or diaphragm capsule that serves as the pressure sensing element. Here’s a brief introduction to what you need to know about aneroid performance.

Understanding Metal Bellows Manufacturing Methods

April 7, 2016

You can’t begin to talk about metal bellows performance without considering manufacturing methods. All key performance parameters depend on the way the bellows is formed or welded. Let’s take a look at two of the most common manufacturing methods: seamless hydroformed bellows and seam-welded formed bellows. Seamless hydroformed bellows. As their name suggests, seamless metal bellows […]

Designing With Metal Bellows

July 14, 2015

Metal bellows have long been a key component in demanding sensing and sealing applications. In fact, they’ve become so familiar that many engineers now think of bellows as generic items: Just specify a few key dimensions, pick a metal alloy and you’re good to go. The reality, however, is that not all bellows technologies are […]
