Support jack load cell

BROSA support jack load cells reliably monitor the forces on support cylinders. Due to the special design of the sensors, they are extremely insensitive to forces in deviation of the measurement direction and transverse forces. Thus, the axial forces can be accurately measured at each base, even on uneven or sloping surfaces. Optimal stabilization of emergency vehicles or mobile equipment can be ensured at any time with the support jack load cells. Due to the rugged construction with high-quality materials, the sensors are ideally suited for continuous operation.

  • There are various applications in which our support jack load cells are used:
  • Mobile cranes
  • Fire trucks
  • Mobile concrete pumps
  • Lifting platforms

By default, our support jack load cells offer additional features in addition to a customized design:

  • Insensitive to diagonal introduction of force
  • Integrated amplifier (4-20mA, CANopen, optional Safety, PROFINET, optional 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%
  • 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)
