The first weigh module certified under National Sanitation Foundation (NSF) reduces contamination risk and increases processing efficiency in industrial settings by allowing efficient Cleaning in Place (CIP).

A new video shows applications for the weigh modules, including junction boxes in sanitary design compliant with NSF. It shows all critical points for hygienic cleaning and state-of-the-art solutions of the weigh module and the junction box.

Weigh Modules and Junction Boxes with Sanitary Design

Complying with the most recent hygienic guidelines is a challenge for most weigh modules. It requires design features that are not typical for standard weigh modules, junction boxes or load cells.

METTLER TOLEDO offers weigh modules and load cells, including junction boxes, that are certified by NSF with the following key features:

  • Capacities 110, 220, 550, 1100, 2200 and 4,400 kilograms
  • NSF certification as standard
  • Fully self-draining for fast drying; avoids standing water
  • Mirror polished for minimal bacteria accumulation
  • Hardware available in 304 or 316 stainless steel
  • Stainless-steel load cell, IP68 / IP69K
  • OIML, NTEP, ATEX, FM approvals as standard

As fully integrated weighing solutions, SWB805 MultiMount weigh modules reduce contamination risk and comply with hygienic standards while increasing processing efficiency in industrial settings. Bellows are designed to be protected from contamination or damage and do not need to be opened for installation, further reducing contamination risk. A mirror surface-polish also dramatically reduces opportunities for bacterial contamination, as does the fact that weigh modules are fully self-draining to avoid standing water.

SWB805 MultiMount weigh modules are also extremely versatile. They are offered in a wide range of capacities from 110 up to 4,400 kilograms, making them appropriate for a wide variety of applications. Perhaps even more importantly, they offer solid weighing performance at nearly any orientation. That makes them exceptionally easy to integrate into your equipment.


Hardware is available in 304 or 316 stainless steel for durability, and stainless steel load cells are rated IP68/IP69k for excellent ingress protection. OIML, NTEP, ATEX and FM approvals are all standard to ensure these modules meet your most stringent regulatory and processing requirements.

To further expand their versatility, SWB805 MultiMount modules can be used with mixer tanks with stabilization accessories that do not compromise the modules’ hygienic nature. Adding NSF-certified junction boxes and sealing accessories further facilitates easy installation and clean operations.

In short, SWB805 MultiMount weigh modules are a unique and ideal solution for sensitive applications in food and pharma applications where durability, accuracy and cleanliness are of paramount importance.
