Sensing Linear Position in Telescoping Hydraulic Cylinders
Telescoping Hydraulic Cylinders find uses in everything from raising the bed of a dump truck, to the massive riser tensioner cylinders used on offshore oil rigs. Telescoping cylinders were first designed to provide long stroke lengths where the total length
Industrial Applications for a CPI Thermal Cutoff Switch
CPI Thermal Cutoff Switches offer some of the most reliable and dependable temperature control in the industry, and as such have many unique applications where an uncompromising approach to thermal switch design is needed. Our product family has a calibration
What Is An Electromechanical Limit Switch?
In the broadest sense, a limit switch is an electromechanical device designed to detect the presence or absence of another physical object, usually a piece of machinery that moves or travels. Perhaps one of the best ways to understand limit
What is a Micro Switch?
So called “Micro Switches” have been around for many years and are made by a large variety of manufacturers. While the Micro Switch trademark is owned by Honeywell (who did not invent it, merely purchased it…), it has become part of
Electromechanical Switch Endurance
If you’re an engineer concerned about the reliability of your switch in a hostile, demanding operational environment, then you’re worried about electromechanical switch endurance. In applications like limit switches, safety interlock switches, door open/close switches, and many others, failure of
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
5 Reasons You Can’t Kill Our Plunger Switches
CPI has been making waterproof limit switches in a variety of form factors for over 50 years now and the simple message about our switch products is: “built to last”. Our stuff is tough, made of stainless steel and carefully engineered
LVDT Based Position Sensors Offer Greater Longevity In Harsh Environments
Accurate sensing of linear position in hydraulic cylinders takes on more complex design considerations when targeting applications where a rugged outdoor environment is the operational norm. Environmental considerations include: Heat – Not just ambient temperatures but the temperature of hydraulic
Taking Limit Switches to the Limit
Applications for CPI limit switches are often safety related or critical to the performance of a machine where failure would be catastrophic. (or catastrophically expensive to fix…) Add requirements such as 5 million electro-mechanical cycles, precise actuation points, and a
Comparison of Hydraulic Cylinder Position Sensing Technologies.
For over a decade the same basic technologies have dominated the landscape of hydraulic cylinder position sensing for harsh environments. Recently a hybrid solution developed by Control Products Inc of East Hanover NJ, has solidly entered the field providing increased
