Industrial LVDT Displacement Transducer | Position Sensor | AML/IE

Robust, Long Life and Highly Configurable, for Harsh Environments

Description

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

Constructed from stainless steel, the AML/IE LVDTs are sealed to IP65 as standard with the option of IP68 (submersible), making them ideally suited for a multitude of harsh and demanding applications where environmental conditions are humid, wet, dusty or dirty.

The basic AML/IE industrial LVDT displacement transducers have an AC mV/V output 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.

Applied Measurements AML/IE industrial LVDT offers a choice of mechanical configurations including captive guided core & extension rod, which is standard, plus spring-loaded core & extension rod with ball-end or guided core & extension with spherical rod-end bearings.

Please see our full range of LVDT displacement transducers and position sensors.  We can also offer a comprehensive variety of supporting instrumentation.  Contact Applied Measurements expert and friendly technical team to discuss your requirements.
