The MTL precision magnet tensioning brakes range comprises six basic models covering a variety of torques, loads, speeds and application configurations.
It is easier to use, more reliable as it has no moving parts and is less vulnerable to dust ingress.
The new ultrasonic sensor continuously monitors the profile of the web and outputs the data as a 0-10V DC signal to the Placid power supply so that torque automatically varies as roll-size changes.
Tension is then adjusted by a remotely mounted potentiometer.
With a resolution of 2mm and repeatability of 4mm, the ultrasonic sensor is designed to be used both with Placid brakes for producing unwind or payout tension or Placid clutches for rewind tension. Request a free brochure from Huco Dynatork ...
