By Josh Coford, Contributing Editor Temperature, pressure, and displacement are typical transducer offerings. A linear displacement transducer measures linear position or distance, especially when high accuracy is needed. Linear transducers work using a principle called magnetostriction. A typical transducer uses three major components; the sensor assembly, a waveguide and a permanent magnet. The sensor assembly […]

What are the differences between proportional and servovalves?
By Josh Cosford, Contributing Editor The line that separates the performance of servo and proportional valves has blurred in recent years. Some may consider a servovalve to be any valve capable of accurately positioning your actuator with closed-loop control. However, in everyday hydraulic circles, many industry professionals describe a servovalve as a valve with a […]
Precision is key in agricultural machinery
The use of GPS technology, coupled with the power and precision of hydraulics, ensures modern farming success. By Josh Cosford, Contributing Editor It’s challenging to find an industry older than agriculture. Humans have been farming for over twelve millennia based on current estimates, making agriculture easily more mature than all other industries outside of carpentry. […]
Electronic control units for hydraulic valve control
Argo-Hytos is launching new sophisticated and versatile proportional electronic control units for hydraulic applications. The EL7 control unit offers multiple types of analog input signals (nine) and also gives the user the option to switch to the CAN bus interface. Everything is easily parametrizable via Bluetooth using the ARGO-HYTOS app, which is free to download […]
LunchBox Sessions and FPW take to YouTube Live again
Last year, Fluid Power World partnered with the experts at Lunchbox Sessions to promote special, free YouTube Live training sessions to bring accessible fluid power training to the world during lockdown. And although many people are back at work, there is always a need for quality education on hydraulic systems, so we are continuing this […]
Hydraulic and pneumatic Colorflow valves adapt to digital age
Contributed by Mike Giammo, product sales manager, and Mitch Eichler, business development manager, Parker’s Hydraulic Valve Div. Parker Colorflow valves have been a global standard in industrial and mobile applications for more than 60 years. The exclusive colored rings found on metering, flow control and needle valves provide users highly visible checkpoints that allow for […]
Bosch Rexroth reveals fast, power-dense Hägglunds Atom hydraulic motor
The smallest of the Hägglunds hydraulic motors from Bosch Rexroth has been transformed. The Hägglunds Atom takes over from the existing Hägglunds CAb — supplying not only more revolutions per minute, but also far more power than motors of similar size. The result is a tiny, power-dense package suitable for mobile, marine and recycling applications. […]
Hydraulic cylinder repair: Metric in an Imperial world
By Josh Cosford, Contributing Editor We live in a global village where local preferences seem to matter less, and acceptance of unfamiliar ideas more widespread than ever. Thirty years ago, the idea of metric bolts, nuts, threads or other objects measured in round numbers was cringe-worthy, especially in the manufacturing space. Many found it annoying […]
What is the best raw material for hydraulic cylinder repair?
By Josh Cosford, Contributing Editor When your customer’s cylinder arrives on your dock for repair, how often do you consider raw material when you quote the overhaul? Probably very little. Most hydraulic cylinders are manufactured from a combination of 1018/1020 cold rolled steel for the “square” components such as flanges, heads and caps. Piston rods […]
Load-sensing gets it done in forestry
Logging and timber harvesting machinery rely on load-sensing electrohydraulics for efficient, productive operation. Contributed by Carl Dyke, LunchBox Sessions In agriculture, like any other large-scale commodity, productivity and efficiency are keys to profitability and competitiveness. In corn harvesting, for example, it is not uncommon now to find harvesters with 2,000 hp and harvesting headers wider than […]
