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).
