Strain Gauge Displacement Sensor | Linear Position Sensor | AML/SGD

Highly Accurate, Long-Life, with a Low Power Consumption
Category: Tags: ,

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.

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.
