MHR-V SERIES Miniature Vented Case, High Temperature AC LVDT SPECIFICATIONS Vented case for submersed applications Operating pressure up to 10,000 PSI Operating temperature 392F 200C Small size and low mass core High output signal Stroke ranges from 0.025 to 1 inch AC operation from 2kHz to 20kHz Stainless steel housing Imperial or metric threaded core The MHR-V Series LVDTs are a variant of the legendary MHR Series. The MHR-V is specifically designed for submersion in inert gas, mineral oil, and other non-aggressive oils (consult factory for medium compatibility) under pressures up to 10,000 FEATURES PSI 700 bars . Compact size With a diameter of just 3/8 inch 9.5mm , the MHR-V Series 10,000 PSI equipressure operation allow precision measurements in space restrictive installations 392F 200C continuous operation at temperatures up to 392F 200C . The extremely lightweight Lightweight core core makes the MHR-V an excellent choice for applications Stainless steel case where excessive core weight could influence the motion with less inertia, accurate measurements at higher displacement Calibration certificate supplied with speeds are easier to achieve. The lightweight core also reduces each unit mechanical stresses and helps preserve the structural integrity of the core actuation assembly. APPLICATIONS The high output sensitivity resulting from the close electrical Immersion applications (oils, inert coupling between the coil and core provides ample signal for gasses) interfacing with practically all signal conditioners and Subsea Oil & Gas equipment conditioning circuits. The magnetic stainless steel housing Down-hole tools and oil drilling provides electromagnetic and electrostatic shielding. equipment Hydrostatic test chambers Hydraulic spool valve feedback Available in a variety of stroke ranges from 0.025 to 1 inch, Automotive transmission servo the MHR-V is compatible with the full line of Measurement testing Specialties LVDT signal conditioners.
