Description
Applied Measurements amplified strain gauge displacement sensor AML/SGDA utilises strain gauge technology to provide a linearly proportional industrial output in relation to the movement of a captivated spindle. Outputs available for the amplified displacement sensor are 4-20mA, 0-5V and 0-10V.
Stroke ranges available are from 0-5mm up to 0-100mm, the strain gauge displacement transducer offers excellent accuracy of better than 0.1% on ranges from 0-5 up to 0-50mm and 0.2% on the 0-100mm versions, along with excellent resolution and long-term stability.
The design principle incorporates a low-noise signal conditioner, avoiding the need for external modules and simplifying the installation and configuration process.
Common applications for Applied Measurements AML/SGDA include Geotechnical Testing, R&D, Aerospace, Civil Engineering and Automotive.
Applied Measurements can supply a wide variety of instrumentation to complement your AML/SGDA amplified 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 is 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 |
