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

24-02-2015 | Ixthus Instrumentation | Test & Measurement

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.
