Comptrol Load Cells are high quality, and rarely need to be serviced after installation.

We have been building Load Cells for superior Tension Control since 1952, over 50 years! Best reputation in the industry for Durability, Accuracy and Dependability. Comptrol Load Cells fit applications in all industries.

A Complete Line of Web Tension Control System Products

Many industries today rely on web tension. Web Tension refers to tension within a moving web of material. For example, when material is pulled through rollers, it must have a continuous amount of tension on it, and this tension varies depending on the application. Controlling this tension can be done in several ways, but one of the most accurate methods involves a load cell called a tension transducer.

Web tension is so important because, in order to wind or unwind rolls of material you must have constant tension on the system. In many applications, the required tension is very specific and this takes accurate measuring equipment like a web tension control system.

Our designs also provide a number of features only Comptrol tension transducers have to offer:

  • Capacity ranges from 4-20,000 pounds
  • Up to 5 volts DC output direct from the transducer
  • 1000% overload protection (10 times the rated load capacity)
  • Mount at any angle around the axis
  • Work in either tension or compression
  • Zero tare adjustment
  • Adjustable Tension Ranges (Superloadcell only)

Standard Options:

  • Stainless Steel Construction
  • Dual Range Superloadcells
  • Corrosion Resistant Paint
  • High Tare Monocells
  • Air Purge for Hazardous Environments
  • Vacuum Enviro Compatable Electronics
  • 0-10VDC/4-20 milliamp amplifier output

Call us today for Upgrades, Retrofits, New production lines or replacement load cells. (COMPTROL load cells can be mounted at any angle and can easily ‘drop in’ to any existing application). Any size load cell can be adapted, (don’t let our competition tell you we are too big or too rugged) we work just as easy with paper as we do with film, steel and even plastic wraps, etc. There are no limitations to materials used for our measurement capabilities!

You will find Comptrol’s web tension control system working hard in a wide-range of commercial and industrial applications today. Many of our load cells being replaced today were made back in the 1970s and 80s. Click this link to our Web Tension 3D CAD Model Configurator.
