Mobile equipment manufacturers are always striving to get the most out of their machines without overburdening the system with costly and complex mechanics. Moreover, performance expectations are not only shaping machine needs but also safety requirements. Consequently, this has driven many engineers to design closed-loop systems featuring electronic sensors as feedback devices. For example, manufacturers […]

New position sensor for hydraulic cylinders offers almost no stroke loss
Mobile machine designers are often faced with the following dilemma: accommodating quite a large functionality in the smallest possible installation space. Some mobile machines and utility vehicles must comply as well with unambiguous regulations regarding the width or height of the vehicle. The difficulty of this task becomes particularly evident when additional functions are to […]
New differential pressure gauge for any budget
Ashcroft 1140 series differential pressure gauges are the budget-friendly solution in applications that do not require all stainless steel protection. These gauges feature a sturdy glass filled nylon front case that allows the window to be easily removed and cleaned. No additional hardware is required for either direct or panel mounting. Designed for either liquid […]
Webtec hydraulic flow monitoring range now compatible with biodegradeable fluids
Webtec has unveiled its FlowHUB ViscoCorrect, an innovative and intelligent hydraulic flow monitoring device with integral temperature measurement and large digital display, now for use on oils, water and water-based fluids. Martin Cuthbert, MD of Webtec said, “We have seen more customers asking for a flow monitoring solution that they can take from stock and […]
Miniature linear position sensors operate reliably in high-pressure hydraulics
The operating environments of many hydraulic and materials testing systems require linear position sensors that operate reliably under continuous high pressures and temperatures while fitting into restrictive spaces. NewTek Sensor Solutions, Pennsauken, N.J., offers vented versions of its M-375 miniature LVDT linear position sensors specially designed to provide the highest level of reliability and accuracy under […]
Tough transducers ensure precise road maintenance while reducing machine downtime
Roadtec manufactures a variety of road building and asphalt paving equipment, relying on hydraulics for the power density and precision control it provides in cutting, paving and more. The company’s soil stabilizers and road reclaimers are well balanced and constructed with a sealed box frame to make them as durable and versatile as possible. Used […]
Position sensor technology comparison for hydraulic cylinder feedback
Contributed by Edward E. Herceg, Chief Technology Officer, Alliance Sensors Group a div. of H.G. Schaevitz LLC As the demand for increased control and functionality has increased over the years, sensor- instrumented cylinders are becoming more important in the heavy industry, subsea and mobile equipment worlds. Position feedback sensors for hydraulic or pneumatic cylinders have […]
Customization enhances pressure switch functionality
Pressure switches are often considered commodity items. But for many mission-critical or demanding applications, including high-pressure hydraulics, aerospace, pharmaceuticals and more, a switch may require a custom mechanical design or electrical features that go beyond what commercial off-the-shelf switches can offer. In fact, with a little extra engineering, users can boost a switch’s performance and, […]
Hall-effect transducers ensure correct axle width to match crop row spacing
When the planting season begins, farmers will plant different crops at different row widths, requiring the sprayers to match the row width by running wheels between the plants and not over them. In the past, changing the axle width was a time-consuming task, as users would have to jack up one wheel of a tractor/sprayer, […]
What does pressure really mean?
Pressure is simply the force applied perpendicular to the surface of an object per unit area over which that force is distributed. However, there are many ways to reference and identify pressure, which is largely dependent upon the application. In many applications, there is a common misconception that all pressure measurement needs to be absolute. […]
