New Paper Explores How Pressure Switch Customizations Overcome Design Challenges

New Paper Explores How Pressure Switch Customizations Overcome Design Challenges

May 21, 2018

Pressure switches are often considered commodity items. But for many mission-critical or demanding applications—including aerospace, pharmaceuticals and chemical processing—your switch may require a custom mechanical design or electrical features that go beyond what commercial off-the-shelf switches can offer. With a little extra engineering, you can boost the performance of your switch and even overcome challenges […]

Flush-Mount Pressure Switches—And Transducers Too

Flush-Mount Pressure Switches—And Transducers Too

January 22, 2018

Food, pharmaceutical and chemical processes often use tubular equipment to mix, transport or store materials. In these applications, it’s a good idea to keep any internal switches or sensors from protruding too far into the tube—where they can create a toehold for material buildup or impede flow. That’s where our newest pressure switch design comes […]

Thermal Lockout for Hermetic Pressure Switches

Thermal Lockout for Hermetic Pressure Switches

December 5, 2017

In hydraulic systems, cold start-ups often cause pressure switching errors that disappear once the system reaches its normal operating temperature. The culprit behind these false high pressure signals is increased fluid viscosity, which temporarily increases the differential pressure across the diaphragm or pressure sensing device. A thermal lockout mechanism based on a snap-acting, temperature-sensitive bimetallic […]

Off-Road Vehicle Sees Success In Pressure Switch Signal Delay

Off-Road Vehicle Sees Success In Pressure Switch Signal Delay

August 23, 2017

If your hydraulic systems suffer from pressure spikes, your pressure switches may not work as expected. The spikes can trigger the switch prematurely, even though continuous pressures remain below the set point. The result is a hard-to-control hydraulic system plagued by false switching signals. Fortunately, there’s a simple solution to these spike-induced switching errors: Just […]

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 […]

Understanding Metal Bellows Manufacturing Methods

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

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 […]
