Weigh Modules, Load Cells, Weight Sensors

METTLER TOLEDO weigh modules, or weighing modules, are used in food, pharmaceutical and chemical applications.  They are available in various versions depending on the application and environment to meet requirements of OEM machine manufacturers, system integrators and end-users. Weigh modules incorporate SafeLock for fast and safe installation. The weigh module is locked and acts as a solid block protecting the load cell sensor from overload during installation. 

A wide range of accessories are available for weigh modules including stabilizers for use with aggressive mixers and agitators, thermal pads to isolate from conducted heat and shock-vibration pads to dampen shock and vibration. Dead stands for level-control applications are also available.

METTLER TOLEDO offers a wide range of weighing modules from 5 kg up to 300 t capacity. Weigh modules are available in painted steel, zinc plated steel, 304 (1.4301) stainless steel and 316 (1.4401) stainless steel electro-polished. They are available in various legal-for-trade accuracy levels according to OIML R60 and NTEP HB44 starting from OIML 3000e (OIML C3), NTEP 5000d, OIML 6000e (OIML C6), NTEP 10000d to finally OIML 10000e (OIML C10). Weigh modules are available for hazardous area application and are approved according to ATEX, FM (Factory Mutual), cFM (Canada), IECEx and NEPSI. They meet protection classes IP67, IP68 or even IP69K. Weigh modules are available in EN1090 versions made in specially controlled and documented manufacturing process for high safety requirements. Weigh modules support the weightless calibration CalFree or even CalFree Plus allowing for tank calibration on a fingertip.

If we look at this question in simple terms, this can be easily explained. Put simply, a weigh module takes a non-traditional structure and turns it into a scale. And a load cell or load cell sensor is what is found within every 'traditional scale' – let's break that down a little further.

A weigh module takes a non-traditional structure, most commonly a tank, and turns it into a weighing device. This means, when we add weighing sensor modules underneath tank legs, the tank goes from just a structure that was holding a substance, to a weighing structure that is measuring how much substance is within the tank itself.

A load cell, in simple terms, is the heart of every standard scale. Load cells are found in all scales, from a highly sensitive lab balance to a heavy duty floor scale, and everything in between. Load cell sensors are what takes a scale from just a platform and turns it into a sensitive weighing device.
