About the MHR series

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.

Available in a variety of stroke ranges from ±0.005 to ±2.0 inches, the MHR Series can be configured for optional mild radiation resistance (1012 NVT total integrated flux; 107 rads Gamma) and high temperature operation (+220oC). High pressure (vented case) versions are also available (consult factory). The MHR Series is compatible with the full line of Althen LVDT signal conditioners.

Applications for MHR Series

• X, Y, Z stage position feedback
• Wire-die bonding machines
• Cylinder position feedback
• Voice coil testing
• Materials testing machines
• Space restricted installations
