SLB Visão geral
A bending-beam load cell is a force transducer that converts an applied mechanical load into a measurable electrical signal via strain gauges bonded to a metal element that deflects proportionally under load. The SLB belongs to the broader category of strain-gauge load cells, which sit within the sensor hierarchy of load/force sensors -> weighing sensors -> industrial measurement transducers -> sensors. Bending-beam cells are typically used in tank, hopper, platform, and process-scale installations where low profile, hermetic sealing, and high repeatability are required.
Key features of the SLB include 17-4 PH stainless-steel construction, hermetically sealed to IP67/IP68, a six-core shielded cable with strain-relief boot, integrated overload protection to approximately 150% of rated capacity, and laser-welded strain-gauge sealing that eliminates potting failures in humid or wash-down environments. The cell uses a four-wire (plus sense) bridge configuration with a nominal 2 mV/V output and 350-ohm bridge impedance, allowing direct connection to most industrial weight indicators and PLCs.
Typical applications include truck and rail scales, batching and mixing hoppers, tank and silo weighing, in-process checkweighing, and OEM platform scales. The SLB's wide capacity range lets one mechanical design replace several single-capacity beam cells across a product line. When installing the SLB, use self-aligning mounting hardware to prevent side-load errors, and torque mounting bolts to the values listed in the datasheet to avoid preload shifts that compromise zero stability.

Aplicações típicas
SLB é adequado para 6 aplicaçãos: Tank and Hopper Weighing, Truck and Rail Weighing, Batching and Mixing Systems, Checkweighing and Process Control, Platform and Bench Scales, OEM Weighing Equipment.
Tank and Hopper Weighing
The Flintec SLB is widely used in tank and hopper weighing installations where low profile and single-ended mounting are required. With capacities from 200 to 5,000 lb and OIML R60 C3 accuracy, the SLB provides reliable mass measurement for inventory and batching of liquids, grains, and bulk solids. Its 17-4 PH stainless construction and IP67/IP68 sealing tolerate humid, dusty, or wash-down environments typical of food, chemical, and agricultural facilities. The 2 mV/V output at 350 ohm bridge impedance interfaces directly with most industrial weight indicators. Recommended companion products: Flintec SA-1 self-aligning mount, hardware mounting bracket and assembly hardware.
Recomendado
Truck and Rail Weighing
For portable truck scales and in-motion rail weighing, the Flintec SLB's high NTEP rating and 5,000 lb capacity per cell make it a strong choice when mounted in pairs or quads. Each SLB delivers OIML R60 C3 accuracy and 2 mV/V nominal output, supporting legal-for-trade aggregate weighing up to 20,000 lb on a four-cell platform. The full stainless-steel body and IP67/IP68 rating allow outdoor deployment without additional weather protection. Installation should use Flintec SA-1 mounts to isolate side-loads from vehicle dynamics. Recommended companion products: 9363 alternate beam cell (Vishay Revere), hardware mounting bracket.
Recomendado
Batching and Mixing Systems
In multi-component batching and mixing skids, the Flintec SLB provides accurate in-process mass feedback for recipe control. With OIML R60 C3 (3,000 verification intervals) and combined non-linearity plus hysteresis within OIML pLC=0.7 limits, the SLB delivers repeatable ingredient weights essential for product consistency. Its 6-core shielded cable resists EMI from adjacent mixers and VFDs, while the potted, hermetically sealed construction tolerates ingredient dust and cleaning chemicals. The 200-2,500 lb capacities cover most pilot-plant and small-batch production scales. Recommended companion products: SLB-1000 alternate SLB capacity variant, hardware weight transmitter and indicator.
Recomendado
Checkweighing and Process Control
For in-line checkweighing of packaged goods, the Flintec SLB provides fast, repeatable mass measurement at conveyor speeds typical of food and pharmaceutical packaging lines. The 17-4 PH stainless body withstands daily wash-down cycles, and the laser-welded strain-gauge sealing eliminates the potting failures that plague lesser beam cells in humid environments. Combined non-linearity, hysteresis, and TCRO meet OIML R60 with pLC=0.7, ensuring that under/over-fill reject decisions remain accurate across temperature shifts. The 200 lb and 500 lb SLB capacities are ideal for light-product conveyor scales. Recommended companion products: SLB-500 alternate SLB capacity variant, hardware checkweigher controller and reject mechanism.
Recomendado
Platform and Bench Scales
Low-capacity Flintec SLB variants (200 lb, 500 lb) are commonly integrated into bench scales and floor platforms used in shipping departments and laboratories. The single-ended beam topology keeps platform height low, improving operator ergonomics and reducing tipping hazards. With OIML R60 C3 accuracy and 2 mV/V nominal output, the SLB connects to any standard weight transmitter with PC connection for calibration, providing legal-for-trade readings for commercial transactions. Its full stainless-steel body tolerates accidental spills and routine cleaning. Recommended companion products: RL30000 alternate single-ended beam, hardware platform mounting plate and load feet.
Recomendado
OEM Weighing Equipment
Scale OEMs favor the Flintec SLB for product lines that span multiple capacities because the same mounting hardware, cable, and indicator interface accommodate the full 200-5,000 lb range. This standardization reduces BOM complexity and simplifies field service. The 17-4 PH stainless construction and potted IP67/IP68 sealing allow OEMs to ship the same platform for indoor or outdoor, food or industrial, without model variants. With one of the highest NTEP ratings in its class, the SLB also enables legal-for-trade OEM platforms in the US. Recommended companion products: SLB-2500 alternate SLB capacity variant, hardware load cell junction box with surge protection.

Notas de projeto
Always mount the Flintec SLB using Flintec SA-1 (compression) or SA-3 (tension) self-aligning hardware. Rigid mounting transfers side-loads and thermal expansion into the cell, causing zero shift and inaccurate readings. The mounting bolts must be torqued to the datasheet-specified value (typically 50-60 N m); under-torquing allows preload shifts that compromise zero stability over time. The SLB is a single-ended beam and must NOT be loaded in pure tension without the SA-3 hardware kit.
Route the SLB's 6-core shielded cable away from VFDs, motor leads, and other EMI sources. Ground the shield at the indicator end only - do not ground both ends, as this creates ground loops that inject 50/60 Hz noise into the low-level mV/V signal. Use a cable gland at the junction box entry to maintain IP67/IP68 integrity. Keep excitation voltage stable; 10 VDC is standard, and some indicators offer 5 VDC for lower-power consumption. Verify the indicator's excitation matches the SLB's 350 ohm bridge (most modern indicators support 350 ohm cells natively).
Estimated: When designing the weigh structure that hosts the SLB, plan for a safety factor of at least 3x on the maximum live load to stay well within the SLB's 150% overload rating. For a 5,000 lb SLB supporting a hopper, the maximum static load (including product, structure, and dynamic impulses) should not exceed approximately 1,667 lb under normal conditions. Always verify that the weigh platform's center of gravity is co-planar with the SLB's loading axis to prevent moment-induced errors; install check rods or stops to limit horizontal sway without introducing side-loads into the cell.
