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 PSI [700 bars]. With a diameter of just 3/8 inch [9.5mm], the MHR-V Series allow precision measurements in space restrictive installations at temperatures up to 392°F [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, 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 high output sensitivity resulting from the close electrical coupling between the coil and core provides ample signal for interfacing with practically all signal conditioners and conditioning circuits. The magnetic stainless steel housing provides electromagnetic and electrostatic shielding. Available in a variety of stroke ranges from ±0.025 to ±1 inch, the MHR-V is compatible with the full line of Measurement Specialties LVDT signal conditioners. 07/2017 Page 1 MHR-T SERIES Miniature High-Temperature AC LVDT PERFORMANCE SPECIFICATIONS ELECTRICAL SPECIFICATIONS (common) Input voltage Input frequency Test frequency 3 VRMS sine wave 2kHz to 20kHz 2.5kHz (standard) ELECTRICAL SPECIFICATIONS @ 10kHz (recommended operation) Parameter Stroke range Sensitivity, V/V/inch [mV/V/mm] Output at stroke ends, mV/V (*) Phase shift Input impedance (PRIMARY) Output impedance (SECONDARY) Non-linearity @ 50% stroke @100% stroke (maximum) @125% stroke @150% stroke Null voltage (max.)
