Product catalog summary
Overview: The Series 330 3/8" AC Gaging LVDTs are designed for precise linear displacement sensing in a compact, spring-loaded package. They are suitable for applications such as material thickness measurements, surface profiling, and creep testing. These transducers can replace standard dial indicators.
Key Features: The LVDTs offer ranges from ±0.005” to ±1.0” with a non-linearity of ≤ 0.20% and 20 MicroInch repeatability. They include self-lubricating bearings.
Specifications:
  • Linear Range: Varies from ±0.005 inches (0.13 mm) to ±1.0 inches (25.4 mm).
  • Non-Linearity: Less than ±0.25% max.
  • Temperature Range: Operating: -4°F to +176°F (-20°C to +80°C); Storage: -65°F to +176°F (-54°C to +80°C).
  • Temperature Coefficients: Zero: < ±0.001% Linear Range/°F; Sensitivity: < ±0.01% /°F.
  • Sensitivity: Varies by model, from 0.5 to 4 V/in./V ±10%.
  • Input Impedance: Ranges from 245 to 480 Ohms.
  • Output Resistance: Ranges from 135 to 210 Ohms.
  • Maximum Excitation: 15 VRMS.
Mechanical Specifications:
  • Total Length: Varies from 2.45 inches (62.2 mm) to 10.45 inches (265 mm).
  • Shaft Extension: Varies from 0.65 inches (16.5 mm) to 2.60 inches (66.0 mm).
  • Spring Force at Null: Ranges from 0.57 to 1.07 lbs.
  • Frequency Response: Ranges from 4 to 250 Hz.
Accessories: Includes adapters and contact tips for various applications.
High Temperature Version: This version operates from -67ºF to +400ºF (-55ºC to +204ºC) and includes high-temperature materials. Electrical characteristics are adjusted for high-temperature performance.

Series 330-1

3/8 Inch AC Gaging LVDTs The Series 330 3/8″ AC Gaging LVDTs provide precise linear displacement sensing in a compact, spring loaded package. Advanced coil winding techniques are employed to minimize package length and optimize overall performance. Spring forces have been carefully selected to insure the proper balance of mechanical frequency response and tip force. Available in strokes ranging from ± 0.005″ to ± 1.0″, these sensors are ideally suited to material thickness measurements, single or multi-point surface profiling, creep testing, or any other application requiring the use of a small, spring loaded LVDT. These transducers are also an excellent replacement for a standard dial indicator.
