Description
Applied Measurements AML/SGD strain gauge displacement sensor utilises strain gauge technology to provide a linearly proportional voltage output in relation to the movement of a captivated spindle.
Available in ranges from 0-5mm up to 0-100mm, the strain gauge displacement transducer offers excellent accuracy of better than 0.1% on ranges up to 0-25mm and 0.2% on the 0-50mm and 0-100mm versions, coupled with high resolution and long-term stability.
The strain gauge bridge design operates using minimal current, making the AML/SGD suitable for use in battery-powered systems and equipment.
Common applications for Applied Measurements AML/SGD include Geotechnical Testing, R&D, Aerospace, Civil Engineering and Automotive.
Applied Measurements can supply a wide variety of instrumentation to complement your AML/SGD strain gauge displacement sensor, such as handheld indicators, digital displays and amplifiers.

| Operational Notes: 1. The outer case must not be distorted when clamping the sensor. A full diameter clamp is advised. 2. The sensor is not recommended for use in hostile environments without additional protection. 3. Special tools are required to remove the plunger tip (anvil) to avoid damage to the spindle. 4. With the plunger tip (anvil) attached this forms a positive overload protection stop. If the anvil is removed, the threaded end of the plunger must not be allowed to enter the case. |

Case Studies
Applied Measurements’ Displacement Transducers Make Tracks Through Turkey
Applied Measurements were asked to design a bespoke bridge monitoring system for Turkey’s new rail tunnel – The Marmaray Project. We created a bespoke bridge monitoring system using 3 off 50mm AML/SGD displacement transducers, forming a triaxial measurement of each joint. The AML/SGD series of displacement transducers utilise strain gauge technology to convert the linear movement of the joints within the tunnel into an analogue electrical signal. The AML/SGD series of displacement transducers were chosen for their excellent accuracy (0.1%), coupled with their high resolution and long-term stability, making them a perfect transducer for The Marmaray Project.
