Many weighing applications involve tanks, vessels, or process equipment where the entire load is transferred vertically through structural supports.
Eilersen® digital capacitive compression load cells are designed for these installations. They are commonly used in tank supports, vessel legs, reactor platforms, and other process structures where accurate vertical load measurement and long-term stability are critical.
Acuity Process Solutions supplies the full line of Eilersen compression load cells and integrates them into weighing systems for bioprocess and life sciences applications.
Why Choose Compression Load Cells
Compression load cells from Eilersen are commonly used in applications where the full process load is transferred vertically through a support structure. These installations often require stable, repeatable measurement over long operating periods without frequent recalibration.
This makes compression load cells particularly valuable in systems where:
- tanks or vessels must be weighed directly through their support structure
- large process vessels require accurate inventory or batch measurement
- the load is primarily vertical and evenly distributed
- measurement stability must be maintained over long operating cycles
- reliable performance is required in hygienic or regulated environments
For many tank and vessel weighing applications, compression load cells provide a stable and durable solution for long-term process measurement.
Tank and Vessel Weighing
Many process vessels and tanks are supported on structural legs or load-bearing frames where the entire operating load must be measured accurately.
In these systems, compression load cells are installed beneath the support points to measure the vertical force applied by the vessel and its contents.
Example applications
Compression load cells are commonly used in:
- tank and vessel weighing systems
- reactor and hold vessel monitoring
- batching and dispensing by weight
- buffer and media preparation systems
- large mixing vessels and blending tanks
- raw material inventory measurement
- upstream and downstream process vessels
In many bioprocess facilities, these systems provide continuous weight measurement to support inventory control, batch verification, and process monitoring.
Key Design Considerations
To achieve accurate and stable tank weighing, the supporting structure and the way the load is introduced into the load cell must be designed correctly.
Important considerations include:
- load distribution across vessel supports
- structural rigidity and allowable deflection
- protection from lateral forces or thermal expansion
- mounting method and restraint strategy
- washdown or hygienic design requirements
- hazardous-area requirements, if applicable
- calibration strategy and verification requirements
Acuity helps customers evaluate these factors during system design so the weighing system performs reliably under actual operating conditions.
Components & System Integration
Eilersen compression load cells integrate with Eilersen digital weighing modules and digital weighing indicators. Eilersen digital weighing systems support multiple fieldbus interfaces including PROFINET, Profibus DP, EtherCAT, EtherNet/IP, Modbus TCP/IP, DeviceNET, RS485, 4-20 mA, and 0-10 Vdc.
This allows the weighing system to integrate with PLC and process control architectures commonly used in bioprocess and industrial environments.
Calibration Without Weights or Water
In large tank installations, traditional calibration methods using heavy test weights or filling vessels with water can be difficult and time-consuming.
EilerCal™ is a force-transfer calibration solution that allows tank weighing systems to be verified without the need for water or heavy calibration weights. This enables faster verification, reduces contamination risk, and minimizes disruption to production environments.
