Highly durable, the ASM's POSICHRON PCST27 series position sensors with a rod profile design can be easily installed inside the cylinder and precisely detect piston positions under difficult conditions. Also suitable for measurement of fluid levels, they can be used underwater at pressures up to 15 bar. Protected to IP68, the sensors consist of a magnetostrictive waveguide and a movable position magnet. Based on magnetically generated density waves and the measurement of time pulses, this measurement principle suits applications that demand high precision, repeatability and resistance against environmental factors such as vibration, humidity or shock. The sea water resistant stainless steel housing allows use in off-shore locations. Based upon non-contact measurement technology, this position sensor ensures years of trouble-free operation. The absolute output offers linearity up to ±0.02% full scale. Measurement lengths from 0 to 100 or from 0 to 5,750 mm are available. For easy integration into various systems, there is either an analog (with 0,5-10V or 4-20mA), a pulse (start/stop) or SSI output available. Longitudinal cable water tightness is a first in these sensors.
