Variohm EuroSensor is claiming that the Celesco M150 is the world's smallest stringpot or draw-wire sensor. With its miniature conductive plastic potentiometer, robust IP50-rated aluminium housing and nylon-coated stainless steel cable, the M150 can be installed in a volume of less than 20 x 20 x 10mm and provides an essentially infinite linear position resolution over a measurement range of 0-38mm with a +/-1 per cent full-scale accuracy.
Aimed at demanding space-restricted applications such as throttle position feedback and vibration/displacement measurement in vehicle testing, the compact unit is easily installed with two threaded mounting holes and is supplied with a 450mm multi-conductor cable.
With a 10g vibration rating at 30-2000Hz and a potentiometer life rating of 5million cycles, the M150 is designed for a long life in the arduous conditions found in the automotive and aerospace industries.
