Short Stroke DC LVDTs The Series 200 DC-DC LVDTs are precision Linear Variable Differential Transformers packaged with a solid state oscillator and a phase sensitive demodulator. The transducer is designed to work with DC voltages, and has excellent linearity, infinite resolution, and high sensitivity. Input and output circuits are electrically isolated from each other and from the coil assembly housing, making them usable directly in floating or ground return systems. DC indicators, recorders, and control systems can usually be driven directly by the large DC output. The core, when displaced axially within the coil assembly, produces a voltage change in the output directly proportional to the displacement. KEY FEATURES Ranges from ±0.05” to 0.20” Stainless Steel Construction High Sensitivity SPECIFICATIONS - ELECTRICAL MODEL 1. Polarity of excitation must be observed for proper function. Reversal will not damage the unit. OUTPUT, FULL SCALE OPEN CIRCUIT, ±VDC LINEARITY, ±FULL SCALE, % 2. Load Impedance of 50 KOhms minimum required for proper operation. 3. Output polarity will be positive on one side of null, negative on the other side of null. INTERNAL CARRIER FREQUENCY MAX RIPPLE, RMS/VDC Output Range OUTPUT IMPEDANCE, KOhms FREQ. RESPONSE (3 dB down), Hz TEMPERATURE RANGE RESOLUTION BLOCK DIAGRAM DIMENSIONAL DIAGRAM 4. Blue lead is more positive with respect to the Green lead when the core is moved toward the lead end.

All standard units will end with a 0 indicating a core assembly. This core assembly consists of a core brazed to an extension rod that terminates in 1-72 UNF-2A threads. If an option is not selected, option 0 will be provided. Option 1 indicates a core assembly with a smaller core. Core options 2 and...
