    What applications are different types of hydraulic instruments used for?

    • Diagnostic Testers and Monitors for hydraulic systems are in-line sensors for measuring and reporting key values within fluid or oil-based hydraulic systems, such as flow rate, pressure, temperature, and in some cases fluid quality.
    • Digital hydraulic pressure switches are sensors used to track/display fluid pressure levels; they respond to variances in pressure by opening/closing electrical contacts once a certain threshold is reached. They’re often used as automatic feedback and supervisory devices in pressurised fluid systems like hydraulic machine tools, pumps or compressors.
    • Hydraulic circulation sights are installed inline as important maintenance tools in hydraulic fluid systems, giving operators a quick and easy way to perform a manual visual check on fluid/oil levels.
    • Hydraulic column level indicators perform a similar role in a different format, and can often include temperature gauge functions as well.
    • Hydraulic pressure sensors, indicators and displays convert pressure measurements into an analog electrical output signal for easy reference as part of a system monitoring, maintenance and quality assurance setup. Hydraulic pressure sensors are often referred to as transducers, as they read pressure changes as a shift in resistance on their internal electrical circuits, which in turn adjusts the output voltage.
    • Hydraulic test points are leak-proof sealed connecting devices used to monitor and control static and peak system fluid pressure in low- or high-pressure loops. They can be installed inline or connected via hydraulic test point hose, and usually, allow for the venting of air and contamination sampling as part of their role.
