Pressure Switches Combine Accuracy and Reliability for Oil and Gas Operations

Pressure Switches Combine Accuracy and Reliability for Oil and Gas Operations

July 18, 2018

Pressure switches for oil and gas facilities have to meet a set of challenging requirements. Not only should the switch provide exceptional accuracy and reliability, but it also must be suitable for use in hazardous locations—and carry the safety ratings to prove it. Our Model 703-U and 703-UJ explosion-proof pressure switches with piston actuation combine […]

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 […]
