Load cells and how they work


In the industrial market, you’ll find numerous types of tension load cells. There are various types, such as for compression, tension and compression, shear beam, single point, column, etc. Tension load cell, often called “force sensors,” are used on industrial machinery to convert tension (such as from a web or wire) to a signal.

By installing high-quality force sensors, the tension can be determined with accuracy and adjusted according to what’s needed based on the electrical signal given. With web tension control, these can help improve overall product quality and operating conditions. In industries that work with chemicals, plastics, steel, etc., using these types of control products can improve the weighing and batching process as well.

How Do Load Cells Work?

222rtfThey are typically integrated with a closed loop tension control process. The force sensors measure the tension; then an amplifier measures the electrical signal (determined by the sensors) and calculates the output value. This process is often referred to as “signal conditioning.” Once the output value has been determined, it can be used by the machine’s clutch, brake or even a motor drive to determine an accurate torque or speed.

One thing that should be noted about a  tension load cell its ability to change shape when a pressure of a load is applied. It’s important to choose load cells that can withstand the tension from high overloads without being damaged.

Manufacturers such as Carotron, Inc. provide force sensors that withstand load tension from 22 – 2200 pounds! These are LVDT load cells with a high-quality mechanical design for harsh industrial environments. Tip: Check out products online before ordering. You can view specs, features, brochures, manuals, etc. online to determine if the products are appropriate for your application.

Benefits for Your Facility

Installing tension load cells can help reduce material damage and loss during the production process. Reduce down time in your facility by having the best possible controls in place. Maximize profits by producing end products of higher quality and durability. Keep employee morale at its best by helping them reach their production goals.

Minimize wear and tear on your motors, drives, and any parts/products that are affected by tension.

378uytWhen buying tension force sensors for your facility, speak with an engineer if possible to make sure you’re getting exactly what you need. Every application is unique, and you’ll find there are various types on the market. It can be a little confusing, but an engineer can probably tell you what type of products is needed after just a brief explanation of your application.

A high-quality product can provide an affordable way to implement web tension control and other forms of motor control in your facility.
