Applied Measurements Ltd. (United Kingdom) - The Challenge – Accurately Measure Fabric Tension On Furniture Frames. Why do we need an accurate fabric tension tester?
Firstly, fabric tension testing guarantees the fabric being used on furniture frames meets the high quality needed for durability, comfort and support. Secondly, having the incorrect fabric tension can lead to fabric tearing, poor posture support, visually poor fabric quality and a corresponding loss of customer satisfaction and a decrease in sales and profit.
However, different shapes, fabrics and styles of furniture meant there were 2 main problems:
- No starting point of where to apply the force.
- No consistent reference point to measure from.
Trent Thermal Technology needed to create an advanced universal fabric tension tester. To measure both fabric tension and fabric movement, even on different styles of furniture framework and fabrics.
The Solution – Applied Measurements s-beam load cell Accurate DBBSMM Miniature S-Beam Load Cell:
- Compact Only 35mm High!
- Capacities: 0-1kg up to 0-50kg
- High Accuracy: <±0.03%/RC
- Optional IP67 Dust Tight Protection for Harsh Environments
- Available in 2-3 weeks
The DBBSMM miniature s-beam load cell was the ideal choice. Standing at only 35mm high, it was easily able to fit between the domed surface contact pad and the deflection load (see images).
Calibrated to UKAS traceable standards with an Intuitive4 load cell indicator, it was able to offset the pad weight and triggers, with less than 3 grams of force. Thanks to its high precision, the miniature s-beam load cell indicated the vertical force being applied within ±0.03% accuracy.
Plus, the miniature s-beam load cell acted as a pressure sensitive re-set switch for an industrial LVDT displacement transducer, which was used to monitor the deflection of the fabric under a pre-determined load.
Applied Measurements AML/IE Industrial LVDT Displacement Transducer:
- IP65 Dust Tight Protection
- High Temperature & Fully Submersible Versions Available
- Wide Range of Configuration Options
- Friction Free & Long-Life
- Fast & Simple Installation
On initial contact with the fabric, the output from the Intuitive4 load cell indicator triggered a secondary input to an AML/IE displacement transducer, which “zeroed” the movement range. As the weight found its natural resting position, the distance between the first point of contact and the final resting position was displayed (in mm) on an Intuitive4 lite process panel meter.
Constructed from stainless steel, the AML/IE industrial displacement transducer has a dust-tight IP65 protection rating as standard, making it safe to use even in this high fibrous environment. We can also offer high temperature and fully submersible versions to IP68 rating to suit you.
Thanks to Applied Measurements industrial LVDT’s wide range of configuration options, the displacement transducer was able to be tailored to their exact application. Plus, its friction-free operation means it has an incredibly maintenance-free, long operating life.
Precise, Money-Saving Intuitive4 Digital Indicators:
- 10 Point Linearisation for Improved Performance
- Superior Resolution Guaranteed with its 20-bit A/D Converter
- Save Money with its Modular Construction
- Ideal in Demanding Environments
- Available in 1 Week
Both the miniature s-beam load cell and the industrial LVDT were calibrated with Intuitive4 digital indicators to UKAS traceable standards, certifying their traceability to strict national standards. The Intuitive4 digital indicators offer superior resolution and outstanding accuracy thanks to their 20 bit A/D converter and 10 point linearisation. Plus, with their modular construction, you only pay for what you need, saving you money from your already tight budget.
This PCC Enclosure Offers a Neat On-Site Monitoring Solution:
These Intuitive4 digital indicators were housed in a PCC2 desktop enclosure for a portable, neatly styled and robust, on-site desktop monitoring setup. The PCC enclosures are available in different formats that are able to house up to 12 individual panel meters with custom enclosures available for greater quantities if your application demands it.
