Tank Weighing
SWB505 MultiMount™ weigh modules offer rugged construction and many features for easy installation and accurate and reliable tank weighing. Standard lift-off bolt copes with  ipping forces while vertical safety down-stop provides additional safety.

Conveyors and  Mixers

Weigh modules are also designed for dynamic-loading applications such as conveyors, mixers and blenders. SWB505 MultiMount ™provides 360° checking for ease of installation and maximum safety. The rocker pin restores the top plate to its ideal position to maintain accurate, repeatable weight.

Load Cell

Load cells have a rocker pin design that automatically aligns load forces for accurate weighing. These hermetically sealed load cells are rated IP68 and can be used in all environments. The load cells are easy to inspect or replace

Stabilizers

Up to two optional stabilizers can be applied to each weigh module to stabilize a scale subject to heavy vibration, high torque, or in-motion weighing. With stabilizers installed, thermal expansion is still possible, guaranteeing the best weighing performance.

SWB505 MultiMountTM Right the First Time

SWB505 MultiMount™ features ensure correct scale system installation, right from the start. Weigh modules do not compromise on safety – all safety features are built-in. The rocker pin design provides the highest level of weighing accuracy. Service features, including SafeLock™ provide easy and trouble free installation.

Features:
• Integrated lift-off protection

  • Vertical safety down-stop
  • Full 360° integrated checking
  • Ground strap – welding protection
  • SafeLock™ – Weigh module locked for installation
  • SafeLock™ – Load cell protected for installation
  • Dual stabilizer option
  • All load cells with IP68/IP69K and fully stainless steel
  • Global approvals standard on each load cell
  • OIML C3/NTEP III M n:5 or OIML C6/NTEP III M n:10
  • Zinc plated or stainless steel mounting hardware
  • CalFree™: Calibration without test weights

1) The weigh module is rated for these forces in normal operation, a Factor of Safety has been applied by Mettler Toledo.

2)arWning: if loaded statically one time in excess of these forces, the weigh module may yield and need replacing. The Max. Yield Forces do not consider fatigue/cyclic loading and should be approached only in exceptional circumstances.

3)arWning: if loaded statically one time in excess of these forces, the weigh module may break with potential for serious injury and/or property damage.

4)arWning: apply a Factor of Safety appropriate to the application.

5) The top plate will travel downwards by 5 mm (0.2 inches) before the down-stop engages and this ultimate force can be developed.

6) % of Applied Load (A.L.) per mm (in) displacement of the top plate (transverse & longitudinal).

7) 1 or 2 per weigh module. Max permissible longitudinal force per stabilizer.

8) 0 with Stabilizer.
