Macro Sensors' LP750 series linear position sensors are offered with a pre-calibrated, loop-powered 4-20 input/output or a nominal 24V DC input 0 to 10V DC output.
Macro Sensors has released 9mm -diameter hermetically sealed position sensors that offer an infinite cycle life to serve as long-life replacements for failing potentiometers in industrial position measurement applications such as machine tool positioning, hydraulic cylinder positioning, valve position sensing and automatic assembly equipment.
Offering a favorable ratio of a short sensor body length to sensor range, the LP 750 series linear position sensors are ideal for long-stroke applications where sensor length needs to be essentially the same length as the stroke of the device.
The sensors can be implemented for "in cylinder" use within the hydraulic rams of construction equipment, which require sensors with a significant stroke to length advantage (0.75% to 0.9%) and robustness.
Because the sensors are constructed entirely of stainless steel and IP68 sealed against hostile environments, they can operate in harsh and corrosive environments with high reliability.
The frictionless position sensors offer infinite cycle life for greater performance and reliability than pots.
Available in standard ranges of 100 to 600mm, Macro Sensors' LP750 series linear position sensors are offered with a pre-calibrated, loop-powered 4-20 input/output (LPIR model) or a nominal 24V DC input 0 to 10 V DC output (LPER model).
In addition to high resolution, excellent repeatability and low hysteresis, the LP 750 series position sensors have a maximum linearity error of +/-0.25% of full-scale output.
