Digital deflection measuring system for suspended structures

  • Modular system: basic configuration with 3 measuring units
  • Expandible up to 6 units
  • DATALOG 8, 8 channels datalogger, in-built battery operated with rigid carrying case suitable for use on field. 5.7” touch screen colour graphic display
  • Displacement transducers with 50 mm travel and 12 m cable allowing increase manageable on site
The determination of deflection of ceilings, bridges or any suspended structure, can be easily performed using this modern digital system. This independent data acquisition unit, equipped with in-built rechargable battery, touch screen graphic display and removable USB pen drive, is ideal for testing application where the data must be verified as soon as they are acquired or in case of programmed medium and long term acquisition.
The testing set includes DATALOG 8,  8 channels multipurpose data logger with rigid carrying case suitable for use on field, 5.7" touch screen graphic colour display; three telescopic supports with 3 displacement transducers 50 mm stroke.    
Additional transducers with telescopic supports and PC software can be ordered separately.  See link to other products below for further details of DATALOG 8 - Battery operated version.
