Applied Measurements were approached and asked to manufacture a 3-channel digital displacement measurement system to replace an ageing and difficult-to-monitor mechanical system based on dial gauges. The result was a neat, user-friendly, high accuracy system based on a strain gauge sensing principle and coupled with the very latest digital indication technology, all delivered within 2 weeks and backed up by an expert team of engineers.
The basis for the system was the strain gauge-based AML/SGD displacement sensor that has been designed specifically to offer high resolution and accuracy in applications where the more conventional choice a LVDT or potentiometer type sensor does not offer sufficiently precise performance.
In this instance a 10mm version of the AML/SGD was calibrated over a +/-3mm measuring range with a resolution of 10 microns, although this can be extended to 1 micron or even 0.1 micron if demanded. The AML/SGD is a spring-loaded displacement sensor design available with measuring ranges from 0-5mm up to 0-100mm.
On indication duties were three Intuitive2-L strain gauge input displays. These highly flexible panel-mount displays were chosen as they can be used with any common type strain gauge transducer (and even some uncommon ones!) to provide a highly stable reading from their six 14mm high LED digits. The Intuitive range offer excellent flexibility with the ability to build in both analogue and digital outputs plus a set of 2 or 4 alarm relays.
The three indicators were coupled with a 3-way PCC desktop enclosure (our primary choice for any desk-mounted, mains powered measurement system) to give the system a clean finish and keep all interwiring contained, leaving the user to simply connect the three transducers to their corresponding connectors on rear of the PCC3 and attach a standard 3-pin IEC mains cable.
Prior to despatch each displacement transducer was calibrated with its allocated indicator using our custom-designed in-house test equipment and a set of UKAS-calibrated slip gauges and issued with a calibration certificate that is Traceable to National Standards.
