Product Overview

Mettler Toledo junction boxes enable quick and safe integration of multiple analog load cells into weighing systems. Our precision junction boxes are designed for hazardous areas with ATEX and IECEx certification, as well as food and pharmaceutical applications meeting EHEDG design rules with GMP and NSF certification.

Critical Performance Considerations

As an analog component where voltage changes as small as 0.1 µV can be significant, junction box design directly impacts scale accuracy. Mettler Toledo's precision junction boxes are engineered to resist temperature fluctuations, maintain long-term stability, and correct corner-load errors while reducing installation time and improving maintenance ergonomics.

Durable Construction

Our junction boxes feature IP67 or IP69K stainless-steel enclosures with high-accuracy electrical components. Available in 304 (1.4301) or 316 (1.4401) stainless steel housing materials for maximum durability.

Advanced Technology

Unlike junction boxes using trim-pots, our models employ precision discrete resistors that provide superior immunity to temperature and humidity effects. Rotary switches select arrays of precision resistors for easy corner error correction, combining the accuracy of discrete resistors with user-friendly operation.

Frequently Asked Questions

What is a load cell junction box?

A load cell junction box is an enclosure designed specifically for use with load cells, which measure weight or force. It connects multiple load cells together to create an accurate weighing system.

How do load cell junction boxes affect scale performance?

Junction boxes are critical for scales using multiple analog load cells, affecting accuracy through temperature sensitivity, long-term stability, and corner-load adjustment. Mettler Toledo junction boxes provide exceptional stability and easy installation features.

How can a junction box affect scale accuracy?

Our junction boxes combine discrete resistors for high accuracy and long-term stability with rotary switches that provide simple user interfaces similar to trim pots, but without their sensitivity issues.

What materials are used in junction box construction?

Our junction boxes are made of rugged 316 stainless steel and FDA-certified stainless steel, with optional materials including polyamide (Nylon), carbon steel (zinc plated), or stainless steel to meet various budget requirements.

How does a load cell summing box work?

Load cell junction boxes (sometimes called summing boxes) connect multiple load cells to a single signal read by the indicator. Despite the name "summing box," these devices actually average the signals from multiple load cells in a weighing system.
