1DFE Tension Measurement & Control The Dover DifferenceDover Flexo Electronics
2Why do customers choose DFE for tension control? “DFE specializes in one technology area for our customers in the converting, printing and web processing industries. If you require tension measurement or control, we offer everything you need.” --Ken Ekola, President
3What sets DFE apart? Value Innovation Leadership Product Focus High quality, competitively priced products and unmatched technical supportInnovation LeadershipNo other tension control manufacturer offers as many cutting-edge products for measurement and control applicationsProduct FocusTension sensing, monitoring andcontrol are all we do.
4What Sets DFE Apart? Broad Standard Product Range Fast Delivery Exclusive Extended Range (XR) optionboosts tension measurement range from 50:1 to 100:1 for wider application.
7What Sets DFE Apart? Customer Support Largest Tension Control Engineering and Support Staff in North AmericaExpert Technical SupportAlways available 24/7/365 by phone or atCode Blue urgent request serviceExperienced Applications SupportFast, Friendly Customer Service
8What Sets DFE Apart? 35 years of Satisfied Customers More Tension Transducers on machines in North America than any other manufacturer
9PRODUCTS Tension Transducers Some call these ‘load cells’, or ‘tension sensors’Tension Transducer Amplifiers and IndicatorsAutomatic Tension Controllers (analog and digital models)Pneumatic Dual Disk Brakes
10Tension Transducer Advantages Stainless steel andaluminum construction forbetter corrosion resistance thancompetitors who offer platedsteel construction.Precision RecessedSeals protect inside thetransducers from dust,water and the industrialenvironment.
11Tension Transducer Advantages Extended Range (XR) is an exclusive option of DFEtension transducers that increases their effectiveoperating range from 50:1 to 100:1. XR allowscustomers to run a broader range of substrates (andtensions) with the same transducers.
12Tension 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.
13Model C Tension Transducers Eight Standard Load Ratingsfrom 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.
14Model 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)SFLPBTFPiloted Flange Mount enables transducer to fit in place of standard RFC 3” piloted flange bearings.PFL
15Tension 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 providessuperior overload capacity and strength.
16TR Tension Roll® Transducer Save Engineering Time. The TR Transducer installseasily in place of an existing idler roll anywhere in the web path.Connector at one end only eliminates cable-crossing between machine frames.
17Narrow Web NWI™ Transducer Cantilevered idler roll andtwo tension transducers inone unit – for high accuracyand fast, simple installation.For Narrow Web machineswith single-side frame.Widths from 7 – 20 inches(178 to 508mm)Optional LED Readoutand 0-10 VDC output.Screw mount or Flangemount.
18Heavy 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 aluminumfor harsh environments, like paper processing.
19Tension Amplifiers & Indicators Tension signal amplifiers, interfaces andindicators provide a tension readout andvoltage or current output proportional totension.Output can be used as reference to controltension manually.Signal can be used tointerface with drivesystems, controllers,computers, or recorders.
20TI17C 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.
21iAmp™ Inline Transducer Amplifier Compact tension transducer amplifier(50mm x 75mm x 25mm) mounts ontransducer cable or on transducer.Saves space, expense and installation timeversus standard amplifiers or interfaces.Powered by 24 VDC. Outputs 0 – 10 VDCisolated for PLC, motor drive or other controller.Easy-to-setup zero and calibrationpotentiometer adjustments.Optional built-in LED tension readout.
22WebHandler™ 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, storageand recall of multiple job setups, serial access via computer withWindows-based software, and many other features and options.
23Pneumatic Dual Disk Brakes Available in 5 standard sizes.From 6 inch (15 cm) up to18 inch (457 cm) diameter disks.Wide torque rangefrom 3 to 17,990 lb-in.Large heat dissipation capacity.Simple friction pad removal andinstallation – no tools required.Brakes fit easily in place of competitivedual disk brakes.Limited travel pistons prevent diskscoring.Universal actuator return springcannot puncture the diaphragm.
