The LP750 Series Linear Position Sensors also offer excellent stroke to length ratio, making them ideal for long stroke applications. With the ability to be almost the same length as the stroke, the LP750 Series opens new possibilities in using this sensor technology in place of 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, frictionless position sensors withstand the harsh and corrosive environments found in steel mills, power plants and petrochemical plants. Their reliability and capacity to withstand high ambient temperatures make them ideal for use in the position feedback of steam control valves in power plants while their significant stroke to length advantage and environmental robustness in environmental extremes enables their use in cylinders implemented in hydraulic rams such as those found in construction equipment. The LP750 Series Linear Position Sensors can also be used in petroleum applications to provide down-hole drill head directional drilling position feedback control and valve position.
Units also operate reliably and accurately while buried in oil and under water pressure. A low operating frequency allows the signal process to be remotely located in applications of high temperature and radiation. With remote electronics, the linear position sensor can operate up to 500 deg F and 30 million Rads.
Offering frictionless position feedback similar to the potentiometer, the LP750 Series Linear Position Sensors have no parts that wear out, offering unlimited cycle life and greater performance than a pot. Units incorporate a digitally enhanced analog output that, with the unique coil winding configuration, enables a compact design much reduced in size in comparison to an LVDT. Microprocessor electronics also provide better unit-to-unit consistency and non-linearity.
Macro Sensors’ LP 750 Series Linear Position Sensors (macrosensors.com) are available in standard ranges of 3.75 (95 mm) to 24” (600 mm) and are offered in three outputs including a 5 VD DC input with 0.5 to 4.5V DC output, a pre-calibrated, loop-powered 4-20 input/output or a nominal 24V DC input 0 to 10 V DC output. The low voltage, power regulation 5V DC input works with micro-controlled based systems and allows the signal processing electronics to be located remotely in hostile applications such as high temperature, vibration, shock and radiation.
