MHR SERIES Miniature General Purpose AC LVDT SPECIFICATIONS FEATURES Compact size Lightweight core ±0.25% linearity (100% stroke) Shock and vibration tolerant Stainless steel case Calibration certificate supplied with each unit APPLICATIONS X, Y, Z stage position feedback Wire-die bonding machines Cylinder position feedback Voice coil testing Materials testing machines Space restricted installations SENSOR SOLUTIONS /// MHR Series Rev. 8 Small size and low mass core High output signal Stroke ranges from ± 0.005 to ±2 inches AC operation from 2kHz to 20kHz Stainless steel housing Imperial or metric threaded core The legendary MHR Series LVDTs provide precision measurements in space restrictive applications. With a diameter of just 3/8 inch [9.5mm], and an extremely lightweight core, the MHR Series is ideal 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. The high temperature operation (200oC) model, MHR-T is available for stroke ranges of ±0.025 to ±1 inch. A High pressure (vented case) model, MHR-V is also available. The MHR is compatible with the full line of Measurement Specialties LVDT signal conditioners. Like in most of our LVDTs, the MHR windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, and the coil assembly is potted inside its housing with a two-component epoxy. This provides excellent protection against hostile environments such as high humidity, vibration and shock. 5/2016 Page 1 MHR SERIES Miniature General Purpose AC LVDT PERFORMANCE SPECIFICATIONS ELECTRICAL SPECIFICATIONS (common) Input voltage 3 VRMS sine wave Input frequency 2kHz to 20kHz Test frequency 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) MHR 005 ±0.005 [±0.13] 8.70 [343] MHR 010 ±0.010 [±0.25] 6.05 [238] MHR 025 ±0.025 [±0.64] 8.10 [319] MHR 050 ±0.05 [±1.27] 3.15 [124] MHR 100 ±0.10 [±2.54] 2.80 [110] MHR 250 ±0.25 [±6.35] 2.07 [81.5] MHR 500 ±0.5 [±12.7] 1.96 [77.2] 43.5 60.5 202.5 157.5 280 517.5 980 MHR 1000 MHR 2000 ±1 ±2 [±25.4] [±50.8] 0.77 0.49 [30.3] [19.3] 770 980 +38° +20° +21° +8° +5° +7° +7° -1° -15° 84Ω 165Ω 238Ω 419Ω 400Ω 345Ω 264Ω 155Ω 504Ω 302Ω 300Ω 485Ω 154Ω 200Ω 420Ω 810Ω 450Ω 1780Ω 0.15 0.25 0.25 0.30 0.15 0.25 0.35 0.50 ±% of FR 0.15 0.25 0.25 0.30 0.20 0.25 0 .50 / / 0.50 / / Non-linearity @ 50% stroke @100% stroke (max) @125% stroke @150% stroke Null voltage (max.) 0.20 0.10 0.25 0.25 0.30 0.35 0.40 0.35 2.5% FRO 1.0% FRO Parameter MHR 005 MHR 010 MHR 025 MHR 050 MHR 100 MHR 250 MHR 500 ±0.005 [±0.13] ±0.010 [±0.25] ±0.025 [±0.64] ±0.05 [±1.27] ±0.10 [±2.54] ±0.25 [±6.35] ±0.5 [±12.7] ±1 [±25.4] ±2 [±50.8] 3.19 [126] 3.36 [132] 4.36 [172] 2.55 [100] 2.40 [94] 1.73 [68] 1.60 [63] 0.70 [27] 0.47 [19] 16 33.6 109 127.5 240 432.5 800 700 940 +73° +59° +58° +36° +30° +33° +23° +6° +3° 59Ω 78Ω 116Ω 141Ω 135Ω 147Ω 145Ω 100Ω 304Ω 260Ω 192Ω 286Ω 90Ω 125Ω 268Ω 445Ω 370Ω 13620Ω @ 50% stroke 0.20 0.10 0.15 0.15 0.15 0.15 0.15 0.20 / @100% stroke (max) 0.25 0.25 0.25 0.25 0.25 0.25 0.25 0.25 0.25 @125% stroke 0.30 0.35 0.25 0.35 0.25 0.35 0.30 (**) 0 .50 / @150% stroke 0.40 0.35 0.30 0.50 0.30 0.50 (**) 0.75 (**) / / 3% FRO 1.5% FRO 0.15 0.15 0.25 0.25 0.35 0 .30 (**) 0.50 (**) 0.75 (**) 0.5% of FRO ELECTRICAL SPECIFICATIONS @ 2.5kHz (standard calibration) Stroke range Sensitivity V/V/in [mV/V/mm] Output at stroke ends, mV/V (*) Phase shift Input impedance (PRIMARY) Output impedance (SECONDARY) Non-linearity Null voltage (max) MHR 1000 MHR 2000 ±% of FR 0.5% of FRO (*) Unit for output at stroke ends is millivolt per volt of input voltage (**) Requires special reduced core length SENSOR SOLUTIONS /// MHR Series Rev. 8 5/2016 Page 2 MHR SERIES Miniature General Purpose AC LVDT ENVIRONMENTAL SPECIFICATIONS & MATERIALS Operating temperature -65°F to +300°F [-55°C to 150°C] Shock survival 1,000 g (11ms half-sine) Vibration tolerance 20 g up to 2KHz Housing material AISI 400 Series stainless steel Electrical connection Six lead-wires, 32 AWG stranded Copper, PTFE insulated, 1 foot [0.3m] long (longer wires optional) IEC 60529 rating IP61 Notes: All values are nominal unless otherwise noted Electrical specifications are for the test frequency indicated in the table Dimensions are in inch [mm] unless otherwise noted FR: Full Range is the stroke range, end to end;
