The AML/SGD strain gauge displacement sensor is the flagship performer in our range, offering 0.1% accuracy on ranges up to 50mm and 0.15% accuracy on the 100mm version.  Being strain gauge-based the AML/SGD requires very low power (29mA @ 10Vdc excitation) and also provides a high output sensitivity to ensure lowest possible noise.

The compact Ø17.4mm body diameter design features a spring loaded plunger with a superbly smooth operating action that gives sub-micron resolution and an operating life of many millions of cycles.  These qualities make the AML/SGD ideal for many long-term research and testing applications.

The strain gauge bridge design offers low power consumption (less than 29mA @ 10 Vdc) and a high output sensitivity (more than 5mV/V).  These features make the sensor suitable for use with all common types of strain gauge input instrumentation including indicators, displays, amplifiers, signal conditioners, data acquisitions systems, digitisers and PLCs and wireless telemetry systems.  Our most popular instrumentation accompaniments configurations are shown below.

The high stability, precision and long life span of the AML/SGD makes it ideal for all types of analytical or reference use or for long term testing where excellent stability and thermal performance are of paramount importance.

If you require a USB output we can modify the AML/SGD strain gauge displacement sensor to use with a USB digitiser for PC monitoring & data logging. What’s more, we can adapt the AML/SGD strain gauge displacement sensor for wireless monitoring, please contact our sales team to discuss.

As with all our LVDT type position sensors, the sensing principle is contactless which makes it an extremely robust, long-lived sensor.

Suitable Instrumentation for the Strain Gauge Displacement Sensor

We can supply a high precision strain gauge indicator for the strain gauge displacement sensor.  It offers superior accuracy and high resolution thanks to its 10 point linearisation.  The intuitive4-L offers a modular construction, meaning you can configure it to suit your needs and only pay for the features you require.  Our intuitive4 ‘lite’ strain gauge digital indicator version is a low cost version with no additional add on features and ideal for those low budget applications.
