INPRO Technologies represents a line of tension
control equipment manufactured by Dover Flexo
Electronics. www.dfe.com Tension control is often used
in manufacturing or printing processes such as
unwinding, rewinding, extruding, slitting, sheeting,
coating, laminating, braiding, embossing and embedding.
Proper tension is needed for high quality output in all
of these operations.
DFEs tension control
products are designed to be integrated into your machine
structure wherever your application demands them.
Reliable, durable, easy-to-install components, including
transducers, indicators, controllers and brakes, are the
hallmark of a complete DFE tension control system. DFE
offers a 5-year product warranty, 24/7 technical support
and 30 years of leadership in the industry.
Available models include:
· Model C The industry standard in tension
transducers, this model mounts on the ends of a live or
dead shaft idler roll.
· Model TR The tension roll is an easy-to-install unit
that combines tension transducers and idler roll in one
· Model RS The Roll Shell transducer locks into the
inner diameter at each end of an aluminum or steel tube
to create a tension-sensing roll.
· Model NW The Narrow Web transducer features a
cantilevered design in widths up to 14-inches.
· Model VNW The Very Narrow Web transducer measures
tension in webs, ribbons or filaments up to 6-inches
· Model RFA This transducer is suitable for wire,
cable or filaments of plastic, rubber, metal or glass.
· Model THN This Thin Profile transducer is available
for applications with limited horizontal space and
features easy installation with single-bolt mounting.
· Model UPBH and SUPB These under pillow block
transducers are designed for heavy duty, high tension
DFE offers a wide range
of tension indicators, including tension signal
amplifiers and interfaces with or without display
meters. Either 0-10VDC voltage or 4-20mA current
outputs, proportional to tension, can be used to
interface with drive systems, controllers, computers, or
recorders. Indicators can also be used as a visual
reference for operators to control tension manually.
Options are available to customize any indicator to fit
Available models include:
· True Tension Interface, TI-17B/TI-18B available as a
bare card, a card and mounting bracket, DIN-rail
mounting, or CE-marked in a full enclosure.
· TI-5 Indicator displays tension in any of three
ways: at the left edge, right edge, or total web
· True Tension TI-14 Indicator This is a
general-purpose indicator for measurement and display of
total web tension. An optional Tension Limit Switch
activates at high or low preset tensions.
· SteadyView Digital Indicator Available as a Ό DIN
panel mount enclosure or a wall mounted enclosure. Both
use programmable, microprocessor technology in a
compact, easy-to-use package. Features serial interface
with a PC or PLC.
· IAmp Inline Amplifier These enclosed miniature
amplifiers are powered by a 24VDC and output 0-10VDC
isolated signals proportional to tension. The amplifier
can be mounted directly to the connector on most
· MAC MultiAmplifier Card The MAC card is an
eight-channel interface featuring eight independent
amplifiers on a single circuit card.
· TI-11 Dual Transducer Interface This dual-channel
amplifier can be used with one or two pair of
transducers to measure tension in one or two zones. The
card contains two independent circuits with independent
· Fireguard This model is an intrinsically safe
interface between transducers and a controller, drive
system or computer. The UL listed FireGuard reduces risk
of fire or explosion in plant environments where
combustible vapor may be present.
With an automated control
system, you will no longer need to continuously monitor
and adjust tension throughout your operation. DFE
controllers will do it for you. Automatic tension
controllers will save you manpower and improve the
quality of your finished product. Easy to configure DFE
controllers automatically compensate for variations in
roll diameter, speed and web characteristics. All
controllers offer a choice of output for use with an
electric brake, a pneumatic brake, an eddy current
clutch or a variable speed drive. Emergency Stop,
auto/manual control modes and soft start capability are
standard features on all controllers.
Available models include:
· WebHandler3 This digital tension controller is
offered at a highly competitive price. Features include:
touch panel setup and calibration, LCD display,
compensation for speed and roll diameter, soft start,
storage & recall of multiple job setups and serial
access via PC using Window-based software.
· TensionManager This is a microprocessor based
controller for OEM and machine builders. This compact
system is customizable with modular device add-ons.
· SteadyWeb This full-featured analog controller is
known for its reliability and ease of use. Optional
functions include taper tension, dual transducer input,
DC and pulse tachometer inputs and more. System status
lights allow the operator to see the operating mode at a
· WebHandler2 This is a low cost analog controller for
unwind and rewind zones. Its compact size facilitates
easy installation almost anywhere.
· SteadyWeb Splicer This is a complete automatic
turret rewind control system for automating a flying
splice sequence. This controller combines advanced
SteadyWeb tension control, core speed matching controls
and flying-splice sequencing circuitry with a
user-friendly interface. The splicers circuit design
coordinates turret rotation, knife firing, core speed
matching and tension control all at the touch of a
