Standalone inductive sensor for non-contact linear position and displacement measurement

Written by: Tom Austin-Morgan | Published:

Kaman’s digiVIT is a precision inductive sensor system that is claimed to measure linear distance or displacement to any conductive target with nanometre resolution and accuracy. Available from Kaman’s UK distribution partner Ixthus Instrumentation, the standalone digital variable impedance transducer is said to provide easy set-up and calibration. digiVIT self-calibrates for the specific sensor connected, the sensor cable length and whatever conductive target material is used.

What sets digiVIT apart from other digital inductive linear displacement sensors systems is that all set-up functions can be accessed through four pushbuttons on the front panel with no need for connection to a PC – making configuration faster and easier for position, vibration and proximity sensing applications that include parts sorting, process control, laboratory test, engine dynamics testing and condition monitoring.

The pushbutton guided set-up procedure can be configured for 2-, 6-, or 21-point linearity calibration. Pushbutton temperature compensation and zeroing is also provided via the four button keypad. All information is presented on a digital display that reveals percentage of full scale, or a choice of voltage or current output values. Analogue output options are selectable from 0 to 5Vdc, 0 to 10Vdc, ± 5Vdc, ±10Vdc, 4 to 20mA and 0 to 20mA.
