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… Continue reading What is a Micro Switch?
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… Continue reading Electromechanical Switch Endurance
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
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… Continue reading 5 Reasons You Can’t Kill Our Plunger Switches
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… Continue reading LVDT Based Position Sensors Offer Greater Longevity In Harsh Environments
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… Continue reading Taking Limit Switches to the Limit
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… Continue reading Comparison of Hydraulic Cylinder Position Sensing Technologies.
Waterproof Momentary Switch Technology
For extreme duty applications a mechanically activated momentary switch is often a critically necessary electronic component, and can also be a primary operational failure point. CPI’s line of Waterproof Momentary switches have been staying dry and operational for over 40… Continue reading Waterproof Momentary Switch Technology
Safety Interlock Switches – Limit Switch Design Considerations.
One of the most common applications for our high performance Limit Switches is in the area of safety or performance controls for extreme duty machines. These are applications where failure of some component or system would be catastrophic or costly… Continue reading Safety Interlock Switches – Limit Switch Design Considerations.
Improving Safety and Reliability in Hydraulic Accumulator Charge Sensing
Whether using a piston or a bladder, hydraulic accumulators are all about precharge pressure. When sizing an accumulator, specifying the correct volume and precharge pressure can mean the difference between a system that runs smoothly and one that doesn’t. Monitoring… Continue reading Improving Safety and Reliability in Hydraulic Accumulator Charge Sensing
