WWZMDiB Load Cell With HX711 Amplifier (1KG/5KG/10KG/20KG)
Product features include a combination HX711 24-bit ADC with a selection of load cell capacities (1kg, 5kg, 10kg, 20kg). The module supports voltage in a 2.6 to 5.5V range and provides precise readings for force, pressure, displacement, and strain. This kit is suited for compact weighing projects integrated with microcontrollers such as Arduino or Raspberry Pi.
Wishiot 2 Sets 20kg Load Cell Kit With HX711
This pair of 20kg load cells comes with an HX711 amplifier and a straightforward four-lead connection (Red E+, Black E-, Green A+, White A-). Drive voltage is typically in the 5–10V range. The kit outputs a voltage signal proportional to force, making it ideal for DIY scales, laboratory setups, or tank weighing where multiple load cells are used for distributed measurement.
ShangHJ 4 Sets Digital Load Cell + HX711 Kit
The kit features four 1kg load cells with HX711 ADC modules, designed for Arduino and Raspberry Pi projects. Each load cell uses a standard four-wire configuration (Red E+, Black E-, Green A+, White A-), with voltage input in the 5–10V range. Suitable for small to medium tank weighing experiments or scaled-down brewery, chemical processing, or fertilizer tanks where compact, modular sensing is beneficial.
NOYITO 1kg/5kg/10kg/20kg Load Cell + HX711 Combo
NOYITO’s combo emphasizes a sturdy aluminum alloy load cell with strain gauges and pre-attached relief wires. The system supports 0–5kg, 5kg, 10kg, and 20kg ranges, with a high-precision HX711 breakout for rapid, accurate force measurement. The design includes multi-compatibility with microcontrollers and a 22 cm long wiring harness for flexible installation in tank setups or lab benches.
STCELLS Inline Load Cell (2000KG, 25mm)
This inline load cell uses alloy steel and ranges up to 2,000 kg, suitable for robust tank weighing where bulk loads or high-velocity flow processes demand strong hardware. Its compact 25 mm profile makes it compatible with tight spaces in industrial tanks and process vessels. It is designed for high stability and accuracy under dynamic loading conditions.
Wishiot 2PCS Digital Load Cell Weight Sensor Kit (2pcs 10kg)
This two-pack focuses on 10kg per cell with a four-lead connection and a 5–10V drive voltage, producing a voltage output proportional to measured force. The two-pack configuration is well-suited for multi-point tank weighing, enabling redundancy or distributed sensing across larger tanks or vessels in industrial settings.
Buying Guide: Key Considerations For Tank Load Cells
Selecting the right load cell for tank weighing involves balancing capacity, signal quality, environmental tolerance, and integration complexity. Consider the following perspectives to make an informed choice.
- Capacity and headroom: Tanks often require higher capacities to handle full volumes and surge loads. Start with a cell or kit that exceeds the maximum expected load, or plan for multiple cells sharing the weight to maintain precision.
- Signal chain and accuracy: Most hobbyist and mid-range systems rely on HX711 ADCs. Ensure the chosen module provides low-noise amplification and stable readings under temperature changes typical to your application.
- Mounting and form factor: Inline and compact designs help fit into tight tank configurations. Consider the mounting holes, thread sizes (M4, M5, etc.), and the orientation needed for load application.
- Electrical requirements: Review drive voltage ranges (commonly 5–10V) and interface compatibility with your microcontroller (Arduino, Raspberry Pi, or PLCs).
- Environmental durability: Tanks may expose sensors to moisture, corrosion, and chemical exposure. Aluminum or stainless-steel constructs and sealed enclosures improve longevity in challenging environments.
- Redundancy and reliability: For critical tank weighing, using multiple sensors aids data integrity. Independent channels reduce risk from a single-point fault.
- Calibration strategy: Plan a practical calibration routine with known masses to ensure accuracy over time, accounting for drift and temperature effects.
In summary, optimal tank load cell selection weighs capacity against installation practicality and data reliability. Kits with multiple sensors and HX711 compatibility typically offer straightforward field setup, while heavy-duty inline cells address higher load scenarios and industrial environments.
