8. What Sets DFE Apart? 35 years of Satisfied Customers
More Tension Transducers on machines in North America than any other manufacturer

9. PRODUCTS Tension Transducers
Some call these ‘load cells’, or ‘tension sensors’
Tension Transducer Amplifiers and Indicators
Automatic Tension Controllers (analog and digital models)
Pneumatic Dual Disk Brakes

10. Tension Transducer Advantages
Stainless steel and
aluminum construction for
better corrosion resistance than
competitors who offer plated
steel construction.
Precision Recessed
Seals protect inside the
transducers from dust,
water and the industrial
environment.

11. Tension Transducer Advantages
Extended Range (XR) is an exclusive option of DFE
tension transducers that increases their effective
operating range from 50:1 to 100:1. XR allows
customers to run a broader range of substrates (and
tensions) with the same transducers.

12. Tension Transducer Advantages
Mechanical stops that are designed to give higher overload protection than the competition. No failures from web pulls or from operators climbing on the rolls.
Dual cantilever beam design and limited beam travel enhance durability and minimize risk of resonant frequency vibration problems at high speeds.

13. Model C Tension Transducers
Eight Standard Load Ratings
from 10 up to 800 lbs (45 up to 3560N; or 4.5 up to 364 Kg).
50:1 effective load sensing range, standard (100:1 with Extended Range option)
Dead shaft and Live shaft (rotating bearing) models.
Superior seals protect inside from dust and water.
Dual cantilever beam for high strength and accuracy.

14. Model C Tension Transducers
More mounting styles (5) than any competitor.
Screw mount (S)
Pillow Block (PB)
Flange Mount (FL)
Through-Frame (TF)
Piloted Flange (PFL) S FL PB TF
Piloted Flange Mount enables transducer to fit in place of standard RFC 3” piloted flange bearings.
PFL

15. Tension Roll® Transducer
No assembly required.
Tension transducers and dead-shaft idler roll combined into a single, easy-to-install unit.
Time-proven through-shaft design provides
superior overload capacity and strength.

16. TR Tension Roll® Transducer
Save Engineering Time. The TR Transducer installs
easily in place of an existing idler roll anywhere in the web path.
Connector at one end only eliminates cable-crossing between machine frames.

17. Narrow Web NWI™ Transducer
Cantilevered idler roll and
two tension transducers in
one unit – for high accuracy
and fast, simple installation.
For Narrow Web machines
with single-side frame.
Widths from 7 – 20 inches
(178 to 508mm)
Optional LED Readout
and 0-10 VDC output.
Screw mount or Flange
mount.

18. Heavy Duty UPB Transducers
UPB (Under Pillow Block) transducers install under standard pillow block bearings.
UPBH for tension force parallel to top plate. UPBV for tension force perpendicular to top plate.
Load ratings from 100 – 5000 lbs (450 – 22250N)
Made of corrosion-resistant stainless steel and aluminum
for harsh environments, like paper processing.

19. Tension Amplifiers & Indicators
Tension signal amplifiers, interfaces and
indicators provide a tension readout and
voltage or current output proportional to
tension.
Output can be used as reference to control
tension manually.
Signal can be used to
interface with drive
systems, controllers,
computers, or recorders.

20. TI17C TrueTension™ Amplifier
Low-cost, ultra-stable transducer interface for tension measurement.
VDC or 4 – 20 mA isolated outputs proportional to tension.
Quik-Cal™push-button zero and calibration.
CE-marked.
Choice of mounting styles, including DIN rail mounting.
TI18C runs on 24 VDC.

21. iAmp™ Inline Transducer Amplifier
Compact tension transducer amplifier
(50mm x 75mm x 25mm) mounts on
transducer cable or on transducer.
Saves space, expense and installation time
versus standard amplifiers or interfaces.
Powered by 24 VDC. Outputs 0 – 10 VDC
isolated for PLC, motor drive or other controller.
Easy-to-setup zero and calibration
potentiometer adjustments.
Optional built-in LED tension readout.

22. WebHandler™ 3 Tension Controller
Automatic closed-loop web tension controller.
Control outputs include: psi pneumatic, 0-90 VDC, 45 VDC, 24 VDC, and 0–10 VDC isolated and non-isolated.
Touch panel setup and calibration via large, backlit LCD display.
Compensation for speed and roll diameter.
Auto/ Manual control mode, Emergency Stop, Soft start, storage
and recall of multiple job setups, serial access via computer with
Windows-based software, and many other features and options.

23. Pneumatic Dual Disk Brakes
Available in 5 standard sizes.
From 6 inch (15 cm) up to
18 inch (457 cm) diameter disks.
Wide torque range
from 3 to 17,990 lb-in.
Large heat dissipation capacity.
Simple friction pad removal and
installation – no tools required.
Brakes fit easily in place of competitive
dual disk brakes.
Limited travel pistons prevent disk
scoring.
Universal actuator return spring
cannot puncture the diaphragm.
