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.

Case Studies
Universal Fabric Tension Tester for All Fabrics and Styles
The Challenge - Accurately Measure Fabric Tension on Any Style of Furniture. Fabric strength testing guarantees the fabric being used on furniture meets the high quality needed for durability, comfort and support. Choosing the wrong type of fabric can lead to fabric tearing, loss of customer satisfaction and a decrease in sales and profit. Find out how our miniature s-beam load cell, intuitive4-L digital indicator and industrial LVDT displacement sensors were used to determine fabric strength.
