Description

The OBBS bending beam load cell design is suitable for low capacity weighing applications such as batching hoppers where a highly accurate measurement system is required.  They are also suitable for use in conveyor weighing applications.

The bending beam load cell’s high integrity hermetically sealed IP68 bellows and stainless steel construction means that it is ideal for use in process situations where regular washdowns are required to maintain hygiene standards.

Two mounting assemblies are available to suit the OBBS bending beam load cell; the Vessel Mount for static applications and the Shock / Anti-Vibration Mount for mixer, feed hopper and conveyor applications where vibration or transient loads may occur.

If you have an existing installation that you would like to upgrade with higher capacity bending beam load cells, we have custom designs for capacities up to 1200kg in the same form factor.  Please contact our technical sales team via the quick enquiry form, email us, or phone +44 (0) 1189 817339.

The Vessel Mount assembly for both the OBBS Series of load cells is simple to install and easy design into new or existing installations. The mounts can be installed with or without the load cells in position. Plant down time is reduced to an absolute minimum and the risk of damage to the load cell is eliminated during installation.

The mount provides a permanent Integral Safety Jacking System for your vessel.

Vessel Movement due to thermal effects is accommodated with no loss of performance or accuracy by means of it’s built-in Free Motion load adaptor.

A substantial protection plate is positioned above the cable outlet to prevent damage by falling objects or misuse.

Maximum Safety Protection from the effects of wind or accidental collision are built-in. When vessels being weighed are in hazardous areas, heavy duty earth straps ensure that no potential difference between the upper and lower plates occurs. This low resistance path also assists in removing strong welding currents.

Shock Mount for OBBS Load Cells

  • For easy lifting and removal of load cell.
  • Reduces Installation Time
  • Integral Vessel Jacking Facility
  • Anti-Lift Mechanism for Greater Vessel Stability
  • Stainless Steel Construction
  • Rugged Construction

The shock mount assembly is designed to enable successful weighing when a vessel or hopper is subjected to external forces, such as vibration. The complete assembly is supplied enabling the client to source all the items from a single source, reducing the need for in depth research and endless sourcing problems.
