Series 350 Specs Gaging (LVDT) Transducers
4Pages

General Purpose DC Gaging LVDTs The Series 350 DC Gaging Transducers are an integrated package consisting of a spring loaded spindle, precision linear variable differential transformer, a solid state oscillator, and a phasesensitive demodulator. The transducer is designed for 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 spindle, 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 ±3.0” High Sensitivity SPECIFICATIONS MODEL NUMBER WORKING RANGE ± Inches (mm) MECH. TRAVEL, Inches (mm) NOMINAL F.S. OUTPUT ±VDC (tested with load impedance simulating open circuit) @ 6 VOLT INPUT @ 28 VOLT INPUT INPUT CURRENT 6.3 mA @ 6 Volt input to 48 mA @ 28 Volt input LINEARITY % FULL SCALE OVER TOTAL WORKING RANGE ±0.50 INTERNAL CARRIER FREQ., Hz NOM.

BLOCK DIAGRAM Polarity of excitation must be observed for proper function. Reversal will not damage the unit. Load Impedance of 50 KOhms minimum required for proper Output polarity will be positive on one side of null, negative on the other side of null. White lead is more positive with respect to the Green lead when the core is moved toward the lead end.

ACCESSORIES & OPTIONS

ALTERNATE SPRINGS TO BE USED IN OPTION X0038 assembly weight from the tip force. To determine the tip force when the unit is vertical, and pointing up, subtract twice the shaft assembly weight. The weight of the shaft assembly includes both the weight of the shaft and the return spring(s). Both the tip forces and the weight of the shaft assembly are given in grams. To convert this value to ounces, divide by 28.38. The standard springs are designated by an asterisk*. The tip force is given for operation within the linear region of the transducer at full extension (TF-), full compression...
