Dc to dc LVDTS eliminate concerns over power supply selection, grounding issues

RDP ELECTROSENSE DCV Series of dc to dc Linear Variable Differential Transformer (LVDT) provides 0 to 10 volt output that is electrically isolated from the input, eliminating concerns over power supply selection and grounding issues. Units will operate from +14 to +26 volts dc. They are available in measuring ranges from 0.2 inches (5 mm) up to 37 inches (940 mm) with an output of 0-10 volts dc. Transducers use the Linear Variable Differential Transformer (LVDT) principle, making it a robust and reliable position sensor. There is no electrical contact across the transducer position sensing element, ensuring clean data, infinite resolution and a very long life.  http://www.rdpe.com
