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
Momentary Switches for Extreme Duty – Reducing Failure Rates
Momentary Switch Design Parameters Extreme duty applications that require a momentary switch with ultra harsh environmental and duty cycle requirements call for more than just a “weatherproof” or “splashproof” rated component. For more than 40 years CPI’s has made precisely
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
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
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
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
Long Stroke Hydraulic Cylinders Part 2 – Replacing Failed Rod-Type Sensors.
Rod based magnetostrictive position sensors are historically one of the primary types of feedback sensors used on hydraulic or pneumatic cylinders where high accuracy was of primary concern. The sensor (often called an “LDT” or “MLDT”) incorporates a stainless steel
Position Sensing in Long Stroke Hydraulic Cylinders
Long stroke hydraulic cylinders commonly find use in equipment that is subject to extreme environments. This includes heavy duty industrial equipment of the sort found in power plants, oil and gas exploration, deep sea applications, and high-end mobile hydraulics such
