AC-Operated, Long-Stroke
Spring-Extended Armature

The long-stroke Model DS2000 has a threaded mounting shank and locking nut to allow secure, precise positioning in a simple mounting fixture.  For short-stroke "locking nut" LVDTS, see the Models DS200B and DS500.

The coil is epoxy-encapsulated and magnetically shielded, and the spring-loaded probe terminates in a hardened steel tip, rounded and polished, which is readily replaceable (see the optional Model 106 Contact Tip, below).  An optional rubber boot is also available, for protection of the probe shaft from fluids and abrasive materials.

Combining optimal electrical properties with rugged stainless-steel construction, these instruments can tolerate years of hard industrial use with no appreciable loss of precision.  Typical applications include in-process gaging control, creep test recording, structural deflection measurement, actuator and tool position feedback, dilatometry, strip thickness measurement, and much more.

Full Specifications are given below.
