Solid State Tilt Transducer for Damper/Valve Position Feedback TT-470 Series

Solid State Tilt Transducer for Damper/Valve Position Feedback


The Kele TT-470 Series solid state tilt transducer is a programmable, 2-wire, 4-20 mA loop-powered device specifically designed to provide positive feedback of damper or valve position to a building automation system. The transducer is quickly and easily field programmed, using an integral pushbutton, to span any shaft rotational range between 10° and 360° (one full rotation). The TT-470 contains no mercury or other hazardous substances and meets or exceeds all current RoHS environmental standards. The transducer includes an integral crankarm style mounting bracket and is available in 2 models. The TT-470 fits a 1/2" shaft and the TT1-470 fits a 1" shaft. The transducer must be mounted on a horizontal shaft, typically a damper shaft or a globe valve linkage shaft (for example the Honeywell Q5020 linkage).
