MHR-V 250

MHR-V 250 is a MHR-V series miniature vented case high-temperature AC LVDT (variant of the legendary MHR series). This is specifically designed for submersion in inert gas, mineral oil, and other non-aggressive oils under pressures up to 10,000 PSI [700 bars]. It is with a diameter of just 0.37inch and allows precision measurements in space restrictive installations at temperatures up to 200°C. The extremely lightweight core makes the MHR-V an excellent choice for applications where excessive core weight could influence the motion with less inertia, and accurate measurements at higher displacement speeds are easier to achieve. The lightweight core also reduces mechanical stresses and helps preserve the structural integrity of the core actuation assembly. The application includes immersion applications, subsea oil & gas equipment, down-hole tools, and oil drilling equipment, hydrostatic test chambers, hydraulic spool valve feedback, automotive transmission servo testing.
