Overview

About the Fully Digital Load Cell

Fully digital load cells are designed for weighing accuracy, enhanced security and intelligent performance in modern industrial weighing systems. Built-in digital signal processing and diagnostics give stable, tamper-resistant measurements while simplifying installation, calibration and maintenance.

Each load cell communicates digitally over an RS485 bus, so individual cell readings can be monitored and faults pinpointed without opening the junction box.

Applications

Where it is used

Public Weighbridges, Toll & Check Posts

The Public Weighbridge software version produces customised tickets, and we assist with legal metrology stamping.

Steel & Cement

Automated, unmanned weighing with RFID and ANPR keeps queues short and every transaction recorded with images.

Logistics & Warehousing

Flush pit weighbridges let trucks move through without ramps, and remote displays keep drivers informed from the cab.

Installation

Site & installation requirements

Fits weighbridge platforms using the matching mounting accessories.
Digital addressing on the RS485 bus lets each load cell be identified and diagnosed from the indicator.
No long analogue cable runs — the signal stays digital from the load cell to the indicator.

How our installation and maintenance works

FAQ

Questions about this product

Each cell converts its signal inside the load cell and sends it digitally, so it is far less affected by cable length, interference and tampering, and every cell can be monitored and diagnosed individually.

Fully digital load cells are available from 10 t to 50 t, including the DES3 double ended shear beam model in 30 t and 40 t.

The minimum order for the DES3 model is 6 pieces, supplied ex-stock or within 7 days.

Analogue strain gauge load cells output a millivolt signal that is combined in a junction box and read by the indicator. Digital load cells convert the signal inside each cell and communicate over RS485, so every cell can be monitored individually, faults are easier to locate and the signal is more resistant to tampering and interference.

Yes. Share the weighbridge make, capacity, number of load cells and indicator model. Our service team will confirm a compatible replacement or recommend upgrading the weighbridge to digital load cells, then install and recalibrate it.
