What is a load cell junction box?
METTLER TOLEDO load cells and load cell junction boxes enable the quick and safe integration for weighing into any machine for filling, dosing, batching, sorting by weight and check weighing. METTLER TOLEDO load cells and load cell junction boxes are used in food, pharmaceutical and chemical applications.  They are available in various versions depending on the load cell types and applications and environment to meet requirements of OEM machine manufacturers, system integrators and end-users. A wide range of accessories is available for load cells junction boxes to ensure a good load cell junction box connection and an economic load cell junction box price.

How do load cell junction boxes affect the performance of a scale?

The load cell junction box is critical to the performance of weighing scales that use more than one analog load cell. It affects accuracy due to temperature effects, long-term stability and corner-load adjustment. Mettler Toledo load cell junction boxes provide unique long-term stability and easy installation features which ensures a stable load cell junction box connection. Using precision discrete resistors with tight temperature specifications avoid the weaknesses of trim potentiometers like instable contacts over time. The precise resistors are operated by means of gold plated rotary dip switches for making adjustments easy. All load cell junction boxes function with weightless calibration CalFree.

How can a junction box affect scale accuracy?

Load cell junction boxes are often underestimated in terms of their accuracy impact. Load cell junction boxes combine the best of two worlds. Discrete resistors provide high accuracy and long term load cell junction boxes connection while rotary switches combine them to a simple user interface similar to trim pots.

What material are junction boxes made of?
Load cell junction boxes by load cell suppliers like Mettler Toledo are made of very rugged  316 stainless steel stainless and FDA certified stainless steel. The load cell junction box cable entry fitting is available with polyamide (Nylon), carbon steel (zinc plated) or stainless steel which ensure that the load cell junction boxes are available in different load cell junction box price levels.

How does a load cell summing box work?
Load cell summing boxes or load cell junction boxes connect numerous load cells to one signal which is then read by the terminal. These load cell junction boxes are used in scales with more than one load cell. Actually, the name summing box is misleading. A more appropriate name would be an averaging box. These boxes do not add the single load cell to a sum but provide the average of all load cell signals (e.g. a box connected to 4x 50kg 2mV/V LC does not provide 8 mV/V at 200kg, but 2mV/V at 200kg).
