DC-SE SERIES General purpose DC LVDT SPECIFICATIONS Single-Ended DC operation Low 6mA current consumption Stroke ranges from 0.1 to 6 inches 0.25% linearity Stainless steel housing Double magnetic shielding EMI/ESD protected 1 meter long shielded cable Captive core option 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. FEATURES The DC-SE is internally regulated, thus providing immunity to line ripple and allowing operation from unregulated power sources of between 8.5 Unipolar DC operation and 28VDC. The very low typical 6mA current draw is ideal for remote Low power consumption or battery powered applications. The highly stable oscillator provides excellent temperature performance throughout the operating Shock and vibration tolerant temperature range, while synchronous demodulation insures superb Captive core option (available on noise rejection. select models) AISI 400 Series stainless steel The built-in EMI/ESD protection and the shielded cable permit operation in noisy industrial environments, with double magnetic shielding housing providing the utmost protection from stray fields. CE compliant Calibration certificate supplied Like in most of our LVDTs, the DC-SE windings are vacuum with each unit 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. APPLICATIONS Factory floor automation 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 Position feedback metric threaded core, guided core and small diameter/low mass core. Data collection Process control Captive core option: The DC-EC features an optional captive core design (available for most models) that greatly simplifies installation. Metrology The core rod and bearing assembly includes a Bronze bearing on the Portable / battery powered front end for self-alignment, while a PTFE sleeve allows low-friction measurements travel through the stainless steel boreliner (spool tube). The core rod General industrial and the bearing assembly are both field serviceable.
