Curtiss-Wright STT280

Sealed Tilt Sensor, Choice of Measurement Ranges From ±10°, ±20°, ±30°, and ±60°.

The new Curtiss-Wright (Product Brand: Penny & Giles)  STT280 sealed tilt sensor is designed to provide reliable, fit-and-forget tilt measurement sensing within an extremely compact housing, for the most arduous operating environments.

  • No moving parts
  • High-resolution ±0.07°
  • Absolute measurement
  • Measuring ranges ±10°, ±20°, ±30° and ±60°
  • Less than 6.5mA supply current
  • Crush-proof mounting flange
  • Rugged construction, sealed to IP68

The STT280 uses solid-state, 3D-MEMS (Micro-Electro-Mechanical Systems) technology to measure the sensor’s inclination relative to earth’s gravity

The STT280 is suitable for use in applications such as road construction equipment, cranes and booms, scissor lifts, agricultural vehicles, container handling and hydraulic lift systems.
