Transducer range offers expanded stroke lengths

An Applied Measurements product story
Edited by the Engineeringtalk editorial team Jan 13, 2009

A range of strain gauge displacement transducers is now available from Applied Measurements that offers expanded stroke lengths from as low as 0-5mm up to 0-100mm.

The transducers are interchangeable with alternative strain gauge displacement transducer models currently on the market and offer long service life and mechanical reliability.

The AML/SGD Series of strain gauge displacement transducers produces a linearly proportional voltage output relative to the movement of a captive and guided spindle arrangement.

Compared to LVDTs, measuring displacement using strain gauges is generally more consistent and accurate.

The internal construction of the AML/SGD transducer provides a smooth, frictionless movement of the inner core, resulting in minimal resistance and providing overall accuracy of <+/-0.1 per cent.

Due to its virtually frictionless movement, the AML/SGD displacement transducer is less intrusive to the application, particularly if the customer is trying to measure the displacement of soft, pliable materials.

Also, being strain gauge based, the AML/SGD Series utilises simple DC electronics and is compatible with a broad range of standard analogue and digital instrumentation.

The design of the AML/SGD Series is based on a four-arm active Wheatstone Bridge, with a nominal impedance of 350ohms.

The company said that this design ensures excellent non-linearity, low current consumption and good temperature stability.

The transducers are used by several industry sectors, including research and development, industrial, aerospace, civil engineering, automotive and marine/shipbuilding applications.
