How to Identify a Load Cell When the Part Number Is Missing

Load cell identification is a common challenge in industrial weighing systems. Over time, load cell labels can fade, corrode, or become unreadable—especially in truck scales, floor scales, and outdoor installations. When the part number is missing, replacing a failed load cell can feel complicated, but it doesn’t have to be.

This guide explains how to identify a load cell without a visible part number and what information you need to find the correct replacement.

Load cells are manufactured with identification tags that list key specifications.

Why Load Cell Labels Go Missing

Load cells operate in harsh environments, and label damage is common. Some of the most frequent causes include:

  • Moisture and washdown exposure

  • Corrosion from chemicals or road salts

  • Physical wear and abrasion

  • Age and prolonged outdoor use

Even when the label is gone, the load cell itself still provides clues that can help identify a compatible replacement.


Key Information Needed to Identify a Load Cell

When the part number is missing, focus on these critical factors:

  • Capacity – The maximum weight the load cell is designed to measure

  • Physical Shape – Single point, beam, canister, or rocker column

  • Mounting Style – Bolt pattern, end plates, or load button design

  • Cable Length and Type – Standard PVC or braided stainless steel cable

  • Output Signal – Commonly 2 mV/V or 3 mV/V

  • Certification – NTEP approval if the scale is used for legal-for-trade weighing

Matching these characteristics is often more important than matching the original brand.


Where to Find Helpful Clues

If the load cell itself does not show identifying information, check these locations:

  • Load Cells – If there are multiple load cells, check the other load cells for a tag.

  • Junction Box – Labels or wiring diagrams may reference the load cell

  • Scale Manufacturer Plate – Often lists model or capacity information

  • Old Service Records or Invoices – Previous replacements may be documented

These details can significantly narrow down the correct replacement options.


When an Exact Match Isn’t Required

In many cases, an exact part number match is not necessary. Load cells can often be replaced with functionally equivalent models that match:

  • Capacity and safety factor

  • Mounting dimensions

  • Output signal

  • Environmental rating

  • Certification requirements

Using a compatible replacement can reduce lead times and cost without sacrificing accuracy or durability.
