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. […]
Miniature LVDT position sensors operate in high-pressure environments
NewTek Sensor Solutions introduces a miniaturized series of AC-operated position sensors with a lightweight and compact 3/8-in. diameter size that provides highly reliable linear position feedback in rugged industrial applications with tight space and weight restrictions. Resistant to harsh and high-pressure environments, the NewTek M-375 Series Miniature AC LVDTs provide high response dynamic measurement for […]
Position sensor measures up to 5-m length in hydraulic and telescopic cylinders
The new SGH50 wire-actuated encoder from SIKO uses a clever cable mechanism for absolute measurement of hydraulic or telescopic cylinders. The sensor represents the latest generation of the SGH wire-actuated encoder family and now makes it possible to measure distances up to 5 m. Target applications are agricultural machinery, construction machines, municipal vehicles, forestry machines, […]
Wire-actuated encoder as integrated position sensor for hydraulic cylinders
The new SGH25 wire-actuated encoder from SIKO is characterized by a measurement range up to 2.5m and an extremely long service life. The variety of interfaces meets the very highest requirements, even in applications that are critical for safety. With this performance profile, the wire-based position sensor is suitable for applications in mobile machines such […]
Tough gauge comes in small package
When space is limited, Ashcroft 1008S 40mm (1.5”) and 50mm (2”) diameter pressure gauges provide the quality and performance of a larger gauge, but in a smaller diameter. A NEMA 4/IP66 ingress rating and a stainless steel case allow the 1008S to be used outdoors or in harsh environments. Liquid fill or the patented Flutter Guard […]
Linear position sensor adapts to existing hydraulic cylinder designs
Alliance Sensors Group has expanded its in-cylinder position sensor product line to include the MHP-7 series linear inductive sensors. These compact inductive linear sensors were designed to be installed into the rear endcap of hydraulic cylinders for operation at pressures up to 5,000 psig. Their 1-in. hex aluminum or stainless steel housing are ideal for […]
