Montalvo 350 Type FN Load Cell Transducer 50 LB Web Tension Roller 13.5"

Montalvo 350 Type FN Load Cell Transducer 50 LB Web Tension Roller 13.5"

The Montalvo 350 is a Type FN load cell transducer designed for web tension measurement in converting, printing, and coating line applications. It combines the load-sensing element and roller into a single integrated assembly, mounting via a four-hole stainless steel flange to a machine frame while the roller rides directly against the web material to measure tension in real time.

Applications

Montalvo load cell transducers are standard components in web tension control systems used throughout the converting, printing, laminating, and coating industries. The Type FN series is a roller-type transducer: the roller itself spans the web and transmits tension forces directly to the internal strain gauge element, providing a continuous electrical signal proportional to web tension. This signal feeds a tension controller or display, allowing operators to maintain precise, consistent tension across materials such as paper, film, foil, fabric, and nonwovens. Montalvo is a well-established U.S. manufacturer of tension control equipment, and their load cells are commonly integrated with Montalvo controllers and amplifiers as well as third-party tension control systems that accept standard millivolt/volt load cell outputs. These transducers are used in production environments ranging from narrow web label presses to wide-format film lines and industrial coaters.
