DESCRIPTION
The DC-EC Series DC operated LVDTs combine a computer-designed AC LVDT with custom integral signal
conditioning to achieve premium performance. Operating on a nominal ±15VDC supply, the DC-EC Series
delivers an extremely linear, low noise, yet high frequency response ±10VDC output.
Innovative design and manufacturing techniques further enhance the DC-EC performance and cost efficiency.
The micro-miniature components employed were meticulously selected for maximum stability and thermal
performance. Vacuum encapsulation of all elements affords excellent shock and vibration tolerance, while
double magnetic shielding provides the utmost protection from stray fields.
Like in most of our LVDTs, the DC-EC 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.
Available in a variety of stroke ranges from ±0.05 to ±10 inches, the DC-EC Series can be configured with a
number of standard options including metric threaded core, guided core and small diameter/low mass core.
Captive core option: The DC-EC features an optional captive core design (available for most models) that
greatly simplifies installation. The core rod and bearing assembly includes a Bronze bearing on the front end for
self-alignment, while a PTFE sleeve allows low-friction travel through the stainless steel boreliner (spool tube).
The core rod and the bearing assembly are both field serviceable.
Also see our other LVDTs with built-in signal conditioning: DC-SE (single-ended DC voltage), HCD (Hermetically
sealed, ±DC voltage), HC-485 (RS485 digital output), and the HCT (4-20mA, 2-wire loop).
