Control & Automation Load Cell Assembly Modules – Mounting Hardware for Process Weighing Systems
Load cell assembly modules are the mechanical foundation of any process weighing installation — providing the precision-engineered interface between the load cell and the vessel, platform, or structure being weighed. In control and automation applications, where the weight signal drives PLC logic, valve control, batching sequences, and process alarms, the mechanical integrity of the mounting arrangement is just as important as the accuracy of the load cell itself. A poorly mounted load cell introduces side loading, friction, and structural interference that corrupt the weight signal and undermine the entire control system — regardless of how sophisticated the transmitter or PLC programme may be.
Our range of load cell assembly modules covers the most common mounting configurations used in process weighing: compression mounting feet for base-supported tanks, silos, and vessels; rocker pin and self-aligning mounts that accommodate thermal expansion and structural movement without transmitting lateral forces to the load cell; and tension mounting assemblies for suspended hoppers, bins, and reactors. All modules are designed to transfer the process load cleanly and accurately onto the load cell sensing element, while protecting it from the overload, shock, and side forces that occur in real industrial environments.
Modules are available in standard carbon steel and stainless steel construction, with options for high-temperature, hygienic, and ATEX-rated installations. Whether you are engineering a new process weighing system or replacing worn mounting hardware on an existing installation, our technical team can advise on the correct module type, load cell compatibility, and installation arrangement for your vessel geometry, capacity, and process environment.

Frequently Asked Questions
Why does the mounting arrangement affect process weighing accuracy?
A load cell measures force in one direction — vertically, in compression or tension. Any lateral force, friction, or structural constraint acting on the load cell introduces an error into the weight signal that the transmitter or PLC cannot distinguish from a genuine weight change. In process environments, these forces come from thermal expansion of the vessel, wind loading on outdoor silos, pipework connections, and agitator vibration. Correctly specified mounting modules eliminate these error sources by allowing controlled movement at the mounting point while transferring the vertical load accurately to the load cell — ensuring the weight signal feeding your PLC is a true representation of the vessel contents.
What types of mounting modules are available for process weighing?
The most common types are compression mounting feet (for base-supported tanks and silos), rocker pin mounts (which allow the vessel to expand and contract thermally without transmitting lateral forces to the load cell), self-aligning mounts (which automatically level the load cell seating surface to compensate for minor structural misalignment), and tension mounting assemblies (for suspended hoppers and reactors). The correct type depends on your vessel geometry, load cell format, capacity, and operating environment — contact our team for guidance on the right configuration for your application.
How do I prevent thermal expansion from affecting my process weighing system?
Tanks and process vessels expand and contract with temperature changes — particularly in chemical and pharmaceutical applications where process temperatures may vary significantly. If the mounting arrangement does not allow for this movement, lateral forces are transmitted to the load cells, causing the weight reading to drift with temperature rather than reflecting the true vessel contents. Rocker pin and self-aligning mounting modules are specifically designed to accommodate thermal expansion by allowing controlled horizontal movement at the mounting point while maintaining accurate vertical load transfer. For high-temperature or large-diameter vessels, this is a critical design consideration — contact our team for advice.
Can mounting modules be retrofitted to an existing process vessel?
Yes. Retrofit mounting is a common requirement when upgrading an existing process weighing system, replacing worn or damaged hardware, or converting a non-weighed vessel to a weighing installation for process control integration. The vessel is temporarily supported while the existing feet or supports are modified to accept the new mounting modules and load cells. Our technical team can assess your existing structure and recommend a compatible mounting solution — contact us with your vessel dimensions, load cell format, and capacity for advice.
Are stainless steel modules available for hygienic or corrosive process environments?
Yes. We stock stainless steel mounting modules suitable for food, dairy, beverage, pharmaceutical, and chemical processing environments where hygiene, washdown resistance, or corrosion resistance is required. Stainless steel modules meet the construction requirements for hygienic process installations and are compatible with CIP (clean-in-place) cleaning processes. Contact our team to confirm the correct specification for your process environment and load cell format.
