STT series I N S TA L L A T I O N AND A P P L I C AT I O N N OT E S MOUNTING THE TILT SENSORS STT280 See tilt sensor Dimensions on page 5. The STT280 is designed to be mounted on a flat and smooth vertical surface by using 2 x M4 socket head cap screws and M4 washers to retain the mounting flange. The STT280 has two radial slots 4.5mm wide on a 38mm diameter PCD, with the slot length sufficient to allow ±10° offset during attachment. The STT280 will be at approximate mid-span position when the cable outlet is vertically down. The mounting flange is fitted with stainless steel inserts around...

APPLIED VOLTAGES The STT280 and STT500 can operate from a 5Vdc regulated or 8 – 30Vdc unregulated power supply • At 5Vdc the sensor operates from a regulated supply in the range 4.75 to 5.25Vdc and provides a ratiometric output which is 80% of V supply over the selected full range angle of tilt, with 50% of V supply at 0° tilt. The ratiometric output means that any change in the supply voltage will show a proportional change in the output. • Between 8-30Vdc the sensor will operate from an unregulated supply in the range 8 to 30Vdc. This version has an internal voltage regulator and provides...

The cross-axis sensitivity (<4%) shows how much perpendicular acceleration or inclination is coupled to the STT280 or STT500 output signal. For example, if the cross axis tilt is 10°, the added error due to cross-axis sensitivity is less than 0.04 x 10...
