Spyder Plus Tension Controller

Powerful tension control at an affordable price used to control clutches and brakes, or interface directly with a drive

Offers open loop, closed loop, load cell and closed loop dancer control in one compact package

Optional S1 Model offers an additional input for roll diameter, a feature usually reserved for our highest-end controllers

Spyder Plus Overview

MAGPOWR’s cost-effective Spyder Plus Tension Control is capable of controlling web tension in closed loop, open loop, unwind, rewind, point-to-point or dancer applications. It measures tension from one or more MAGPOWR load cells and outputs a corrective analog signal to control a torque device. Its reduced size means it can be neatly hidden away in an enclosure or underneath the machine.

With its Ethernet connection, the easy-to-use Spyder can be viewed on a web browser for remote troubleshooting, programming and/or data collection. Additionally, the Spyder provides an analog input for manual level setpoint, control inputs for Run/Stop, Auto/Manual: Tension On/Off and E-Stop and a 0-1 mADC meter output proportional to measured tension.
