Auto-sensing voltage / current output sensors with easy teach mode for span and zero

Ixthus Instrumentation's new VLPSC series linear position sensors provide precise displacement measurement with teach-mode calibration for zero and span in addition to autosensing 0 - 10VDC or 4 - 20 mA outputs. With a choice of nine electrical travel ranges from 25 to 290mm, the robust and competitively-priced sensors combine tried and tested conductive plastic element technology and integrated signal conditioning electronics to offer a 12-bit resolution, linearity to 0.1% and high positional repeatability. Available for displacement referencing as single components or as part of comprehensive test and measurement system solutions from Ixthus, the rod-style VLPSC series combines the benefits of convenient installation via self-aligning spherical bearing mounts and a compact design that keeps overall length to measured length ratio to a minimum. The 15mm square aluminium housing and improved felt and O-ring shaft seal arrangement provides IP65 protection with IP67 on request. The design features a patented multi-fingered precious metal wiper arrangement that ensures smooth and uninterrupted contact with low electrical noise and high resilience to shock and vibration. The high-reliability sensor has a rated service life in excess of 25 million operations, an operating temperature rating of -40C - +90C and 5% - 95% humidity tolerance. The simple teach function procedure allows referencing the start and end positions for the sensor without the need for a PC connection, using a visual signal from an on-board red/green LED and a single input pushbutton. The VLPSC provides a sampling rate of 4 kHz and a refresh rate of 1kHz for fast position update. Supply voltage is 12 to 24VDC and sensor is delivered with one metre-lead, or optional three-metre lead.
