Sealed Tilt Sensor  No moving parts – MEMS technology  Compact 28mm diameter body  Unlimited mechanical life  Absolute measurement  Measurement range ±10-60°  High resolution ±0.07°  Analog output – 0.5-4.5V  5V or 8-30V supply  Over-voltage protection  Reverse polarity protection  Low power consumption  Sealing to IP68  Crush-proof mounting flange The STT280 is a tilt sensor that is sealed in a compact, 28mm diameter body, which has been designed to provide reliable, fit-and-forget tilt measurement sensing for even the most arduous of operating environments. Solid-state 3D-MEMS (Micro-Electro-MechanicalSystems) technology is used to measure the sensor’s inclination relative to the gravity of the earth. As there are no moving or contacting parts, this sensing method provides distinct advantages in terms of reliability, stability and compactness over fluid based, electrolytic and pendulum operated devices. Four measurement ranges – ±10°, ±20°, ±30° and ±40° – with resolution of ±0.07° are available, and each provides a 0.5-4.5V output analog signal across the angular span, with a nominal 2.5V signal at 0° tilt. A choice of power supply options – 5V and 8-30V – is also offered meaning the sensor can be used in conjunction with a regulated supply or connected directly to an unregulated source, such as a battery. Reverse polarity and over-voltage protection is included, while the current consumption is less than 6.5mA. The sensor body is manufactured from high strength, corrosion resistant material and has a protection rating of IP68. A wide operating temperature range and EMC immunity of 100V/m mean the STT280 is ready for use in the harshest of environments. Typical applications include: road construction equipment, cranes and booms, scissor lifts, agricultural vehicles, container ha
