Magpowr | Position and Diameter Sensors Overview

Scrap is essentially waste, and waste represents reduced profits. An effective way to reduce scrap and therefore maximize profits is by increasing the accuracy and control of the web. MAGPOWR’s US-2 Ultrasonic Sensor used with VERSATEC control measures the diameter of the roll and allows your core and full roll alarms to be adjusted to give your operator proper notification before reaching the end of the roll. This fully automated ultrasonic tension control system allows you to reduce scrap by utilizing the entire roll on your web.

The goal in dancer/follower arm applications is to utilize the dancer arm for increased accuracy in tension control, eliminating dependence on an operator and achieve automatic control of the braking torque on the unwind roll — resulting in constant web tension. MAGPOWR’s compact DFP-2 is perfect for use in dancer control applications with the MAGPOWR VERSATEC, and in dancer and follower arm applications with the Spyder and DFC-90. It offers the same exceptional sensing performance as the original DFP sensor, but in a lighter duty, low cost housing. The DFP-2 also includes a servo-type flexible coupling to allow for misalignment in shaft-to-shaft applications as well as 15 feet of shielded cabling for ease of installation. The DFP and DFP-2 use the same conductive plastic element to measure dancer and follower arm positions.
