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 […]

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 […]

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 […]
