Tilt sensor is suitable for safety-critical applications

Based on proven solid-state technology, the STT500 is claimed to provide distinct advantages in terms of reliability, stability and compactness over fluid-based, electrolytic and pendulum-operated sensors. It can operate from a 5V or 8-30V power source and has a measurement range of +/-10, +/-20, +/-30 or +/-60 degrees with an output from 0.5-4.5V DC over the full inclination angle.

The STT500 features a marine grade (LM6) cast aluminium alloy housing with 88mm diameter flange. It has a high environmental protection rating of IP69K to withstand the ingress of dust and fluids, even under high-pressure washing.

With no moving parts, the sensor has excellent resistance to shock and vibration up to 20,000 'g' and it can withstand operating temperatures of -40 to + 125degC. It has an EMC immunity of 100V/m.

Options

For flexibility, the new sensor has a low-power requirement of less than 6.5mA, so it can be used in hard-wired or battery-powered systems; for ease of installation, OEMs can fit their own cable through the supplied gland or use Penny + Giles' supplied cable option. Alternatively, a circular M12 connector is available that can interface with industry-standard sensor cables.

The company's popular STT280, which has a smaller, moulded housing of just 28mm diameter, is also now available with +/-10, +/-20, +/-30 or +/-60 degrees measurement range options.

Penny + Giles' range of tilt sensors provide a highly reliable option for absolute tilt measurement sensing in a variety of applications such as road construction equipment, cranes and booms, scissor lifts, agricultural vehicles, container handling and hydraulic lift systems.
