Hand Force Load Cell Enables Grip Measurement

March 1st, 2005

hand-force-200x200The grip measurement application required the design of a custom built hand force load cell to enable the customer to determine the ratio between gripping force and friction coefficients of various materials.  The length and overall diameter of the finished transducer were stipulated by the customer and it was important that the load cell could be gripped at any point along its length without compromising the sensitivity and accuracy.

Successful grip measurement was achieved by utilising the basic single point load cell principles but adapting them to meet the dimension specifications.  To enable transducer to be used in a variety of locations, it was calibrated to UKAS Standards with our portable battery powered PD100 Indicator.

From the initial consultation through design and manufacture took only 6 weeks.  This is a typical example of our design and manufacturing capabilities for custom specials.

Digiforce Strikes A Chord at Bison Concrete

March 8th, 2004

digiforce-150x150Bison is the UK’s leading producer of structural, precast concrete products.  Consistent, quality control is vital to maintain the company’s position at the forefront of the sector.

Bison is particularly renowned for prestressed elements, including hollow-core floors, solid composite floors and beams.  Integral to the durability and structural performance of these products is the correct tensioning of the prestressing steel tendons.  There are approximately 30 tendons in the average 1200mm-wide hollow-core floor slab.  These may be up to 160m in length.

The tendon carrier precedes the casting hopper.  It lifts the tendons to the required depth in the slab so that sufficient concrete cover is achieved during casting.

The tensioning equipment must be tested on a regular basis, but current methods are cumbersome and time-consuming to use.  Accuracy is very much dependent on the skill of the operator.

The unique Digiforce developed jointly by TMS Systems, and Applied Measurements has enabled Bison to achieve rapid, highly repeatable, non-contact tension measurement using the latest technology incorporated into their new Digiforce non-contact tension meter.

The Digiforce non-contact tension meter operates on the principle that when a tensioned cable or wire is struck it vibrates at a frequency relative to its tensile stress.  These vibrations interfere with the magnetic field created by the Digiforce and, via unique software, allow accurate force measurements to be made.

The Digiforce non-contact tension meter is quick and easy to use.  Only two inputs are required – the tendon length and the weight in grams per metre.  As the measurement is taken, a reading in KiloNewtons is digitally displayed.  The values can be saved in the internal datalogger and downloaded for quality control purposes.

The Digiforce tension meter is supplied in a robust carry case with a bush hammer for creating resonance and ferrous clips for non-magnetic tendons.  Lookup tables from which to calculate the weights of various types of tendons, cables or strands are also included.  It is also resistant to shocks and rated to IP65 (waterproof).

Compact Under-Hook/Lifting Gear Telemetry Load Cell & Display

May 1st, 2003

et-telemetry-200x200The latest weighing system from Applied Measurements Ltd is one of the first of its kind to use a telemetry link between the load cell and the portable digital display instrument, thus eliminating the problems associated with a long interconnecting cable.

Specifically designed for the measurement of cable tension and under hook crane and lifting gear weighing, the complete ET Telemetry Lift Link system consists of a robust telemetry load cell with an internal data transmitter with a range of 200 metres, together with a portable handheld receiver instrument, displaying the weight digitally.

The ET telemetry load cell is available in ten different ranges from 0-1 to 0-500 tonnes and offers excellent performance with a repeatability of <0.05% of rated output.  It has been designed for use with standard lifting shackles and is sealed to IP66 for waterproofing to withstand arduous outside conditions.

The ET lift link telemetry load cell’s weight and height have been kept to a minimum, thereby reducing the overall headroom required for the installed system.  The portable instrument receives the load cell transmitted signal at typically 420MHz and displays the weigh value on the 8 character 14 segment LCD display, over the range of -4999 to 65000.  Features on the unit include a ‘hold’ control for display storage, and a ‘tare’ control for automatic zeroing of the load signal.  It operates on a 9V PP3 supply, with auto power down to conserve battery life.
