Macro Sensors has designed a position sensor that is hermetically sealed, frictionless and will serve as a long-life replacement for failing potentiometers in a wide range of industrial position measurement applications such as machine tool positioning, hydraulic cylinder positioning, valve position sensing and automatic assembly equipment. Constructed entirely of stainless steel, these hermetically sealed sensors are sealed against hostile environments to IEC standard IP-68. The LP750 position sensors can, therefore, withstand the harsh and corrosive environments found in steel mills, power plants and petrochemical plants. For example, the LP750 position sensors’ reliability and capacity to withstand high ambient temperatures make them suitable for use in the position feedback of steam control valves in power plants while their significant stroke to length advantage in environmental extremes enables their use in cylinders implemented in hydraulic rams such as those found in construction equipment. The LP750 position sensors can also be used in petroleum applications to provide down-hole drill head directional drilling position feedback control and valve position. The LP Series position sensors are available in standard ranges of 4in to 25in and are offered in a precalibrated loop-powered 4-20 input/output or a nominal 24V DC input 0 to 10V DC output.
