Product Overview

What Is a Weight Sensor for Heavy Trucks?

Also called a truck scale load cell, weighbridge load cell or heavy-duty load cell, a weight sensor for heavy trucks is the precision component that turns a loaded truck’s mass into a reliable, billable number.

When a heavy truck drives onto a weighbridge, the load is transferred through the tires to the steel weighing deck, then distributed to multiple load cells at the support points. Each sensor converts mechanical force into an electrical signal, and the weighing indicator combines the signals to display the total vehicle weight.

Heavy-truck sensors are built for a much tougher life than standard industrial load cells — they must survive high shock loads, off-centre loading, mud, pressure washing and extreme temperatures, while keeping trade-approved accuracy for commercial billing, logistics settlement and overload enforcement.

  • Capacities from 10 t to 50 t per sensor, 10–200 t per system
  • 150% safe overload, 200–300% ultimate overload capacity
  • IP68 / IP69K sealing against water, dust and salt corrosion
  • Digital output (RS-485 / CAN) with strong electromagnetic immunity

Two Core Solutions

Two Ways Heavy Trucks Are Weighed

A heavy truck weighing job is either done on the ground (static or dynamic weighbridge) or on the vehicle itself (on-board weighing). Keli supplies world-leading sensors for both.

The Complete Solution: KELISCALES Truck Scale / Weighbridge

Don’t need to build a system from components? The KELISCALES truck scale ships as a complete, engineered weighbridge — deck, digital load cells, indicator and software — ready for heavy-truck weighing from day one.

Electronic Truck Scale weighbridge for heavy trucks with digital display and interfaces

A weighbridge (truck scale) is heavy-duty equipment that weighs full trucks plus cargo. It combines a weighing deck, digital load cells, a weight indicator and weighing software for consistent, trade-ready readings in factories, logistics yards, ports and mines.

10–200 t+Capacity — small delivery trucks to fully loaded semi-trailers
4.5–24 mPlatform length × 2.4–3.4 m width, custom sizes available
Class IIITrade-approved accuracy for commercial billing
Digital CellsAnti-interference, stable in dusty, noisy environments
  • U-beam structure (most popular): 8–14 mm plate, high bending strength, shock-proof — ideal for high-frequency heavy duty.
  • Channel-steel structure: cost-efficient for moderate daily weighing volume.
  • Concrete deck: for special local site and environmental conditions.

Interfaces: Ethernet · RS-232 · RS-485 · Bluetooth — connect to plant automation for automatic data logging, statistics and a full smart-weighing workflow.

6 Requirements That Make a Sensor “Heavy-Truck Grade”

Truck scales operate in the harshest conditions in industrial weighing. Here is what a weight sensor for heavy trucks must deliver — and exactly what Keli builds in.

10 t – 50 t per sensor

High Capacity & Headroom

Single sensors handle 10–50 t; a full system combines 4–8 cells to weigh 60–100 t+ gross vehicle weights without saturated output.

150% / 200–300%

Impact & Overload Resistance

Braking, bouncing tires and falling loads create huge momentary forces. Keli sensors hold 150% safe overload and 200–300% ultimate overload.

IP68 / IP69K

Environmental Protection

Welded hermetic sealing, corrosion-resistant alloy and stainless steel keep mud, rain, pressure washing and salt away from the strain gauges.

Anti-Side-Load Design

Off-Centre & Side-Load Tolerance

Uneven cargo shifts weight left/right and front/back. Bridge, canister and pin structures suppress lateral-force interference for stable readings.

RS-485 / CAN-BUS

Digital Output & Noise Immunity

Digital transmission covers long cable runs and shrugs off EMI from truck motors, radios and site equipment — with per-cell diagnostics.

Long-Term Stability

Creep Control & Temperature Compensation

Outdoor temperature swings and stationary weighing demand low creep and full temperature compensation to keep repeatability day after day.

FAQ

Frequently Asked Questions

Straight answers about weight sensors for heavy trucks.

What is a weight sensor for heavy trucks?+
A weight sensor for heavy trucks — also called a truck scale load cell or heavy-duty load cell — is a precision transducer installed beneath a weighbridge deck or directly on a truck. It converts the vehicle’s mass into an electrical signal, supports capacities from 10 t to 50 t per sensor, withstands impacts and moisture, and feeds weight data to a weighing indicator for display and billing.
How much weight can a truck scale load cell measure?+
Keli truck scale load cells are available from 10 t to 50 t per sensor. A typical weighbridge uses 4, 6 or 8 load cells working together, so complete systems measure gross vehicle weights from 10 tons to 200 tons and higher — from light delivery trucks to fully loaded semi-trailers and mining haul trucks.
What is the difference between analog and digital truck scale load cells?+
Analog load cells send small voltage signals to a junction box before reaching the indicator; digital load cells process and transmit data digitally from the sensor itself. Digital systems make per-cell diagnostics easier, resist electromagnetic interference better, simplify troubleshooting, and integrate smoothly with weighbridge management software — a key advantage in harsh truck environments.
Can Keli sensors be used for on-board truck weighing?+
Yes. Beyond static weighbridges, Keli supplies on-board weighing solutions including pin load cells that replace suspension or trailer-hitch pins, compact bending-beam sensors mounted under dump-truck bodies, and vehicle terminals (such as D12-Y / D39) that upload live payload data via GPS/BDS telemetry to fleet and logistics management platforms.
What IP rating do truck weighing sensors need?+
Heavy-truck sensors face mud, rain, pressure washing, salt and temperature swings. Keli truck scale sensors are built to IP68 (and IP69K where washdown is extreme) with welded hermetic sealing and corrosion-resistant alloy or stainless steel construction — protecting both accuracy and long-term reliability.
How many load cells does a truck scale need?+
Large truck scales commonly use 6 or 8 load cells, though the exact number depends on platform length, sections, capacity, steel structure and vehicle types. More important than the count is that cell capacity, mounting and load transfer are correctly matched to the weighbridge design so all weighing points work together.
Are Keli truck scale sensors trade-approved?+
Yes. KELISCALES truck scales are built to Class III trade-approved accuracy suitable for commercial billing, and Keli’s sensor manufacturing complies with international industrial weighing standards and rigorous in-house environmental testing. See our guide to industrial weighing certifications for details.
How do I get a custom weight sensor for my truck operation?+
Tell our engineers your maximum gross vehicle weight, axle configuration, daily weighing volume, environment, and whether you need static, dynamic or on-board weighing. KELISCALES will recommend the right sensor series and configuration. Contact our sales team for a quote.
