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
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.
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
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… Continue reading Long Stroke Hydraulic Cylinders Part 2 – Replacing Failed Rod-Type Sensors.
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… Continue reading Position Sensing in Long Stroke Hydraulic Cylinders
Engineers and heavy equipment operators responsible for the maintenance of large scale hydraulics in the field, know what’s at stake when these systems fail. Costs to repair and impact to production represent a huge operational risk that can quickly have… Continue reading LVDT Based Linear Position Sensors
