Force sensor washer

BROSA force sensor washers offer decisive advantages thanks to their patented three-point design: the forces flow optimally through the measuring points, thus enabling a high measuring accuracy. Customer requirements can be flexibly, individually and easily implemented. Thanks to the compact and robust design, use in the most unforgiving environments are not a problem.

There is a wide variety of applications in which our force sensor washers are used: 

  • spreader twist locks
  • Straddle carriers
  • Packaging machines
  • Rolling mills

Force sensor washers offer the advantage that they can often be installed into the existing structure to save space. 

By default, our force sensors washers offer additional features in addition to a customized design:

  • Integrated amplifier (4-20mA, CANopen, optional CANopen Safety, PROFINET, optional PROFINET PROFIsafe)
  • Design capable of sustained operation
  • Temperature compensated from -40 ... + 80 °C 
  • High EMC resistance of 200 V/m 
  • No zero drift, i.e. no re-calibration required 
  • Consistent accuracy over the entire temperature range
  • Very easy integration into existing applications
  • Design for tensile and / or compressive forces
  • Load limit 150% and breaking load 300% of the nominal load
  • Security classification PL c / SIL 1
  • Protection class IP66 / IP67 in accordance with DIN EN 60529
  • Calibration of reproduced installation situation including test report

As an option, our sensors also offer the following advantages:

  • Increased border and breaking load, for example 300/500%
  • Temperature compensated to + 160 °C
  • Fault insensitive to magnetic fields up to 300 mT
  • Redundant design
  • Performance Level d (e) in accordance with ISO 13849
  • SIL 2 (SIL 3) in accordance with IEC 61508
  • ATEX Ex i
  • IECEx certification
  • Protection class IP69
  • External amplifiers
  • Customized connections (cables and connectors)
