Macro Sensors” 24V DC-LVDT position sensors are now available in metric versions. Constructed entirely of stainless steel, the HSE/HSER 750 Series of 19.0 mm diameter DC-operated LVDTs are hermetically sealed, making them impervious to dirt, water, steam, and other corrosive elements. The CE-approved units are a good fit for use in hydraulic cylinder positioning, valve position sensing, automatic assembly equipment, and other industrial applications with hostile conditions and corrosive environments. The sensor’s coil windings are sealed against hostile environments to IEC standard IP-68. The housing, bore liner, and end washers are TIG welded, providing a hermetic seal free from oxidation-producing faults that may cause leakage. Available in ranges of 2.5 mm to 500 mm, the position sensors feature high resolution, repeatability (repeatability error <+/-0.01 percent of FSO), and low hysteresis (hysteresis error <+/-0.01 percent of FSO). Standard maximum linearity error for any of these DC-operated sensors is <0.25 percent of full-scale output using a statistically best-fit straight line derived by the least-squares method. Operating from 24 V DC (nominal) or 12-26 V DC, 25 mA (max), the HSE/HSER Series 750 LVDTs offer a full-scale output of 0 to 10 V DC.
