Force measuring pin

BROSA force measuring pins are made of stainless steel and can withstand the toughest requirements. Depending on the application-specific conditions, BROSA force measuring pins are designed and manufactured in accordance with various, partially patented construction concepts. By considering the exact installation situation from design to calibration of the sensors, high measuring accuracies are achieved and ensured in the long term.

There are various applications in which our force measuring pins are used:

  • Booms
  • Undercarriages
  • Chain stoppers
  • Rope endpoints
  • Winches
  • Steel structures
  • Pulleys 

Force measuring pins offer the advantage that they can often be installed into the existing structure to save space. For example, they can be used in place of a bolt in fork bearings.

By default, our force measuring pins 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
  • 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%
  • Overload capacity up to 700% (with force measuring pin MOP)
  • 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 / Ex d
  • IECEx certification
  • Protection class IP69
  • External amplifiers
  • Customized connections (cables and connectors)
