The DC-SE Series LVDTs operate on a single-ended DC power supply,
and provide either a 0 to +5VDC or +1 to +6VDC output signal (wiring
dependent) over their full range of displacement. The extremely linear
and low noise output makes the DS-SE Series the perfect choice for
interfacing to unipolar inputs of analog-to-digital converters, PLC’s, and
various data collection systems.
The DC-SE is internally regulated, thus providing immunity to line ripple
and allowing operation from unregulated power sources of between 8.5
and 28VDC. The very low typical 6mA current draw is ideal for remote
or battery powered applications. The highly stable oscillator provides
excellent temperature performance throughout the operating
temperature range, while synchronous demodulation insures superb
noise rejection.
The built-in EMI/ESD protection and the shielded cable permit operation
in noisy industrial environments, with double magnetic shielding
providing the utmost protection from stray fields.
Like in most of our LVDTs, the DC-SE 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 0.1 to 6 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.
