Positek’s PIPSTM Technology Makes Custom Modification For HighTemperature Automotive Position Measurement Application
Positek Limited, the leading the need for special magnetic UK displacement transducer materials - and for simplified manufacturer, recently control they do not require completed the design and separate signal conditioning. supply of a custom modified As there is no contact version of its PIPSTM equipped between the moving electrical P103 series short stroke linear components, the technology position sensor for a wastegate yields extremely long life when valve position feedback task compared to potentiometer on an advanced automotive based equivalents. Even as turbocharger. As part of a standard components the motorised control system robust technology has excellent that regulates and optimises resilience to shock and vibration peak engine performance, the with respective specification compact pushrod style P103 values of 10g (IEC 68-2-6) is mounted near the direct and 40g (IEC 68-2-29). These flow hot engine exhaust gases factors combine with typical where its specially designed IP67 protection ratings and full thermal shield allows use at compliance to EN61000 for both elevated temperatures of up to susceptibility and radiated EMC. 160 0C at the inductive sensing element whilst the conditioning electronics remain at around 125 For the wastegate valve application, the stainless steel housed P103 series sensor 0C. includes a special threaded Positek’s patented PIPS installation for the customer inductive technology is based as well as the standard options upon a simple, single coil design of spring-loaded pushrod and which facilitates straightforward customisation, often with the benefit of reduced lead times which in some cases can be as short as a few days. When compared with other available cable gland. The electrical characteristics combined a 4.5V DC calibrated output from a +5V DC supply. A wide range of alternative electrical options are available across the standard range along with mechanical LVDT and magneto- strictive options that include flange or sensor types, PIPS based body clamp mountings and free displacement sensors overcome or captive push-rods. problems such as bulky coils, mounting that aided compact poor length-to-stroke ratio or The 35 mm diameter P103 series

short stroke position sensor has any measurement range up to 50 mm (a version for longer measurements up to 100 mm is also available). With independent linearity to < +/-0.25% (< 0.1% option available) and with essentially infinite resolution and a low temperature coefficient, the sensor provides highly accurate and repeatable position measurement over a wide temperature range.
The P103 is part of a comprehensive range of linear, rotary and tilt sensors from the ISO9001:2015 designer and manufacturer which includes ATEX, IEC-Ex and CSA certification across many product lines. Positek’s sensors are widely specified and well proven in challenging environment measurement tasks including intrinsically safe, hazardous area, automotive, aerospace and submersibles as well as general industrial and scientific research applications.
