Draw Wire vs. Variable Inductance Position Sensors

A recent article in an EET Asia technology magazine discussed the advantages of linear position sensors based on variable inductance, as compared to those based on either magneto-strictive or potentiometer based sensors. The article was really a thinly veiled plug… Continue reading Draw Wire vs. Variable Inductance Position Sensors

Linear Position Sensors for High Temperature Environments

Traditional Linear Position Sensor technologies (ie. Magnetostrictive sensors) used in hydraulic cylinders have been limited in their ability to function in high temperature environments. One of the strongest applications for CPI SL series sensors are in these high temperature hydraulics… Continue reading Linear Position Sensors for High Temperature Environments

Linear Position Sensing In Tight Spaces

We’ve said it before but it bears repeating: magnetostrictive sensors are the devil you know, but they aren’t the only game in town… not any more. In fact the need to perfectly core-drill a piston cylinder, the requirements for support… Continue reading Linear Position Sensing In Tight Spaces

Linear Position Sensors for Harsh Environments

For many years, hydraulic cylinder manufacturers were forced to forgo accurate, robust hydraulic cylinder position measurement on the largest, most powerful hydraulic systems: you know, the place where it’s needed most? Since these systems are typically operating outdoors, under extremely… Continue reading Linear Position Sensors for Harsh Environments

Magnetostrictive Position Sensor Replacement – Part II

As mentioned in our last post Magnetostrictive Linear Position Sensors are a common type of position sensor for hydraulic cylinders where high resolution is of primary concern.  The sensor incorporates a stainless steel tubular probe (ie. “the Rod”) and is… Continue reading Magnetostrictive Position Sensor Replacement – Part II

Magnetostrictive Position Sensor Replacement Considerations

One of the prevalent piston position measurement technologies used for mobile hydraulic cylinders is based on the Magnetostrictive properties of ferromagnetic metals. The physics of these sensors is quite complicated, taking advantage of something called the Villari and Wiedemann effects… Continue reading Magnetostrictive Position Sensor Replacement Considerations

Hydraulic Linear Actuator Design Considerations

While there are many types of Linear Actuators ranging from the simple “roller screw” model to sophisticated electro-mechanical, pneumatic, piezoelectric, and hydraulic, a linear actuator generally refers to devices that convert rectilinear or electro-rotational motion into linear motion.  Hydraulic linear… Continue reading Hydraulic Linear Actuator Design Considerations

Really Big Hydraulic Cylinders Are Cool…

For those of us engineering types who derive particular enjoyment from an understanding of how big machines work, one of the most awe inspiring things to understand is the power achievable through large scale hydraulic cylinders. Being a unique supplier… Continue reading Really Big Hydraulic Cylinders Are Cool…

CPI Linear Position Sensor Applications

Since we introduced our first LVDT based position sensors back in 1997, we’ve learned a lot about how to refine and extend this technology into some amazing industrial applications. Originally developed for the mobile hydraulics market, CPI sensors have evolved… Continue reading CPI Linear Position Sensor Applications

Applying Smart Hydraulic Cylinders

What is a Smart (Hydraulic) Cylinder? Smart hydraulic cylinders gain their name from the fact that highly accurate position sensing electronics are integrated with the hydraulics in a single actuator.  Thus these cylinders are “smart” about understanding cylinder position allowing… Continue reading Applying Smart Hydraulic Cylinders
