DC-EC SERIES General purpose DC LVDT SPECIFICATIONS High level 10VDC output Stroke ranges from 0.05 to 10in 0.25% linearity Reverse polarity protection Double magnetic shielding Stainless steel housing Imperial or metric threaded core The DC-EC Series DC operated LVDTs combine a computerdesigned 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. FEATURES Bi-polar DC operation Shock and vibration tolerant Captive core option (available on select AISI 400 Series stainless steel housing CE compliant Calibration certificate supplied with each unit models) APPLICATIONS Materials testing Z-axis position feedback for punchpresses Microscope X-Y stage position control Medical imaging Automotive suspension testing Flight simulators SENSOR SOLUTIONS ///DC-EC Series Rev. 8 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. 07/2017 Page 1 DC-EC SERIES General purpose DC LVDT PERFORMANCE SPECIFICATIONS ELECTRICAL SPECIFICATIONS Parameter Stroke range Sensitivity, VDC/inch Sensitivity, VDC/mm Frequency response Hertz @-3dB Input voltage Input current Output at stroke ends Non-linearity Output ripple Stability Output impedance DC-EC 050 DC-EC 125 0.050 [1.27] 200 7.9 0.125 [3.17] 80 3.15 DC-EC 250 DC-EC 500 0.25 [6.35] 40 1.6 0.5 [12.7] 20 0.79 DC-EC 1000 DC-EC 2000 DC-EC 3000 1 [25.4] 10 0.39 2 [50.8] 5 0.20 3 [76.2] 3.3 0.13 DC-EC 5000 DC-EC 10000 5 [127] 2.0 0.079 10 [254] 1.0 0.039 500 500 500 200 200 200 200 200 15VDC 25mA 10VDC (Positive and increasing when the core is displaced from null position towards the cable) 0.25% of FR, maximum 25mVRMS, maximum 0.125% of FSO 1 Ohm 200 ENVIRONMENTAL SPECIFICATIONS & MATERIALS Operating temperature Survival temperature Shock survival Vibration tolerance Housing material Electrical connection IEC 60529 rating +32F to +160F [0C to 70C] -65F to +200F [-55C to 95C] 250 g (11ms half-sine) 10 g up to 2kHz AISI 400 Series stainless steel Cable with 4 conductors, 28AWG stranded copper, braided shield and polyurethane jacket, 39 inches [1 meter] long.
