Overview
The MK301-M is a bellows weighing module whose welded metal-bellows seal shuts out moisture, dust and corrosive agents in harsh plant atmospheres. A self-aligning loading head keeps the force vertical, so off-centre, side and overload effects are rejected and weighing repeatability stays high. Its compact modular body bolts straight onto equipment feet, with limit devices that stop vessels tipping.
