DESCRIPTION 
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, PLCs, 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.

HC-485 (RS485 digital output), and the HCT (4-20mA, 2-wire loop).
