Description

Applied Measurements AML/E series of standard LVDT displacement transducers are available with measuring ranges from ±0.5mm (0-1mm) up to ±500mm (0-1000mm).

Constructed from stainless steel, they are sealed to IP54 and can be supplied in a variety of mechanical configurations including plain core-only, plain core & extension rod, guided core & extension rod, spring-loaded core & extension rod with ball-end or with guided core & spherical rod-end bearings.

An AC mV/V output is available as standard, with a range of DC voltage signal output options also offered including 0-5Vdc, 0-10Vdc and ±2.5Vdc, as well as a 3-wire 4-20mA current output.

The broad range of typical applications for the AML/E series include Industrial Automation, R&D, Manufacturing and Machine Building.
