Non-contacting inductive technology eliminates wear for submersible rotary sensor

Positek has launched a new rotary position sensor aimed at demanding industrial, vehicle, marine, and offshore angle measurement tasks. 

Protected against water jets and submersion, the compact and durable S508 rotary sensor is fully sealed to IP68 10 bar and IP69K with shaft drive, flange mount and 35 mm diameter housing in 316 stainless-steel. The precision sensor offers an independent linearity to ±0.25 % FSO (0.1% FSO on request) with factory-set angle measurement up to 160°, and full 360° mechanical rotation. 

Maximum performance and reliability is supported with impressive specifications for temperature range, temperature coefficient, vibration, and shock plus an extremely long MTBF life of 350,000 hours at 40 degrees. For maximum application flexibility the calibrated angle output can be supplied in a wide choice of instrument-level voltage and current output options as ratiometric or buffered signals that are available across most common supply input voltages from ±5V DC to ±24V DC.

Positek´s PIPS technology (Positek Inductive Position Sensor) is a thoroughly proven advance in other displacement sensor principles. Developed and refined over several years, the patented technology wins against conventional potentiometric, hall and RVDT with simpler coils and less environmental susceptibility. Positek´s ASIC control electronics interprets the absolute position of embedded inductive coils to provide a proportional, high-bandwidth DC analogue output signal with infinite resolution that requires no external signal conditioning. Furthermore, the cost-competitive technology does not require the use of expensive magnetic materials – and in contrast to potentiometer-based displacement sensors, delivers an extremely long working life.
