When Bi-Metal Thermal Switches Are Really The Only Good Solution
In an era where many applications have gone the way of cheap remote sensors and electronics, there is still a place for electromechanical bimetal switches that is cost effective, reliable and in some cases the only solution to complex operational
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
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
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
Oil & Gas Safety Switch Applications
Explosions and failures that occur in the Oil and Mining industry can have catastrophic results. While not every incident rises to the level of the tragic Deepwater Horizon oil spill disaster in the Gulf of Mexico, the nature of drilling
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
Limit Switch Unlimited Uses – Part 2
The second part in our continuing series on CPI Limit Switch applications highlights a few of the extreme duty deployments where harsh outdoor conditions, high vibration, and heavy usage are the norm. Many of these kinds of implementations can be
Linear Position Sensor Technology Choices
There are a number of technologies to choose from when considering the implementation of a linear position sensor. As CPI’s own sensors focus on the needs of hydraulic cylinder and hydraulic accumulator designers, it is instructive to review the various
Limit Switches – Unlimited Uses.
As one of the worlds leading providers of custom designed, waterproof limit switches for over 50 years, our products have been designed into some pretty diverse applications. Some of them are pretty easy to understand, like the panel mounted kill
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
