Compression Strain Gauge Load Cell by Nipro Weitek

Overview

About the Compression Strain Gauge Load Cell

Nipro compression strain gauge based load cells provide highly accurate and reliable force measurement in compression applications. High-strength alloy steel and precision strain gauge technology give stability, durability and long-term performance under heavy industrial loads.

An ATEX-certified version (model T34) is available for hazardous areas — contact us with your zone classification for details.

Used in truck scales and weighbridges, railway track scales, silo, hopper and tank weighing, hydraulic press force measurement, high-capacity batching systems and mining and heavy industrial weighing.

Applications

Where it is used

Steel & Cement

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

Manufacturing

Weighbridge and process weighing data can be integrated with SAP, ERP or Tally for one source of truth.

Mining & Quarrying

Above-ground pitless designs are easier to clean and inspect, and the Crusher & Mine software version handles material-wise dispatch.

Installation

Site & installation requirements

Use the matching top and bottom mounting plates to allow for the permitted tilt (e° max.).
Mount the cell vertically so the load passes straight through it; avoid side loads on the cable entry.

FAQ

Questions about this product

Instead of a single column, several vertical columns inside the body share the load. This improves load-bearing capacity, resistance to off-centre loading and long-term stability.

Yes. The multicolumn cells carry ATEX certification, and the T34 model is available for hazardous areas. Share your zone classification with us.

Compression strain gauge load cells are available from 15 t to 60 t, and the multicolumn model in 30 tf and 40 tf.

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.
