The MNM 1,000 lb stainless shear beam replacement family is relevant to buyers searching for Celtron SQB SS, Rice Lake RL35023S or RL39123, Sensortronics 65023SS, Revere 9123 and several other stainless single-ended shear beam models. MNM publishes these as interchangeable product families, but a replacement should still be matched by more than capacity alone.
Published Interchange Families
MNM lists Artech SS30310, Celtron SQB SS, HBM B35, Revere 9123, Rice Lake RL35023S, Rice Lake RL39123, Sensortronics 65023SS and Coti Global CG-23SS. These names are useful search references when an existing floor or platform scale needs a compatible stainless shear beam.
Match More Than the 1,000 lb Capacity
Check overall dimensions, mounting-hole spacing, loading-hole position, foot thread, height, cable length, mV/V output, bridge resistance, wiring colors and environmental construction. A load cell can be electrically similar but mechanically incompatible, or it can bolt in correctly while producing a different signal that requires recalibration.
Electrical Matching
MNM's published stainless specification is 3.00 ±0.015 mV/V with 385 ±5 ohm input resistance and 350 ±3 ohm output resistance at 10 V excitation. The listed cable colors are red +excitation, black -excitation, green +signal and white -signal. Never assume another brand uses the same color code; follow the label or datasheet on the cell being removed and the replacement being installed.
After Replacing One Cell in a Four-Cell Scale
Replace the sensor mechanically, route the cable safely, verify polarity, then perform corner correction. A replacement cell can shift the balance even when it has the same nominal output. After corner trim, recalibrate zero and span and verify the full platform at multiple locations.
When to Replace All Four Cells
Replacing one failed cell is common when the remaining sensors are known-good and compatible. A full four-cell kit can make more sense when several cells are corroded, wiring has been repeatedly repaired, the existing cells are mixed models or the scale is being rebuilt for a different environment. The final decision should consider downtime, calibration effort and the condition of the entire platform.
