TECHNICAL BULLETINwww.dfe.com controlling process tension<strong>True</strong><strong>Tension</strong> <strong>TI17C</strong> <strong>and</strong> <strong>TI18C</strong> Amplifier/ IndicatorComparing Output Voltage Over Time at Ambient <strong>and</strong> Cycled TemperatureThe <strong>TI17C</strong> <strong>and</strong> <strong>TI18C</strong> tension indicators have hadtheir internal components upgraded <strong>and</strong>ruggedized over previous generations oftension measurement electronics.140Thorough testing shows that they deliverexceptional output stability, accuracy <strong>and</strong>120signal integrity.100The charts displayed here represent datacollected from two controlled laboratory80tests that DFE's Engineering department60performed on both the <strong>TI17C</strong> indicator<strong>and</strong> a major competitor's top-of-the-line40tension amplifier. The first chart showsthe <strong>TI17C</strong>'s signal output at a constant20low-voltage input <strong>and</strong> at ambienttemperature (~70°F) from startup over0time. It also shows the output of thecompetitor's tension amplifier runsimultaneously under the same conditions.Output (Volts deviation)0.010-0.01-0.02-0.03-0.04-0.05-0.06-0.07-0.08<strong>Tension</strong> Amplifier OutputOver Time at Ambient Temperature<strong>TI17C</strong> vs Major Competitor (Br<strong>and</strong> X)0 60 120 180 240 300 360 420 480 540 600 660 720 780 840 900 960Time (minutes)CHART 1Temperature (degrees F)00.51The second chart shows signal outputs with aconstant input, over a 16.5-hour temperature cycle(75°to 120°F <strong>and</strong> back). The drift in the DFE outputsignal is virtually non-existent at the millivolt level.The drift of the competitor br<strong>and</strong> output tracksalmost inversely with the change in temperature.While the most visible upgrade from the TI17Bgeneration is the time-saving Quick-Cal pushbuttonzero <strong>and</strong> calibration feature, design elementsthat strengthened the amplifier's outputcharacteristics include integrated isolation, circuitstabilization,noise protection, surge protection, <strong>and</strong>current limiting. The <strong>TI17C</strong> retained the footprint<strong>and</strong> connector pinout scheme from the TI17B forbackward compatibility <strong>and</strong> drop-in replacement,<strong>and</strong> the board architecture <strong>and</strong> components havebeen upgraded substantially. The <strong>TI17C</strong> <strong>and</strong> <strong>TI18C</strong><strong>TI17C</strong>Br<strong>and</strong> Xindicators are CE-marked <strong>and</strong> providedrift-free linear performance over a widerange of industrial conditions.Additional <strong>TI17C</strong> <strong>and</strong> <strong>TI18C</strong> features: Quik-Cal Zero <strong>and</strong> calibrationpushbuttons for faster setup out-of-theboxwith no pot adjustments. 0-10VDC isolated output proportionalto tension. 4-20mA isolated outputoptional.<strong>Tension</strong> Amplifier Output<strong>and</strong> Temperature Cycle over Time<strong>TI17C</strong> vs Major Competitor Br<strong>and</strong>1.522.533.544.555.566.577.588.599.5Time (hours)1010.511CHART 2Dual Calibration.11.51212.513Temp (degrees F)<strong>TI17C</strong> (VDC)Br<strong>and</strong> X (VDC) <strong>Tension</strong> Limit Switch (optional) servesas an alarm trigger for web breakprevention.For more information go to www.dfe.com.13.51414.51515.51616.50.10.050-0.05-0.1-0.15-0.2-0.25Amplifier Output (Volts DC change)T H E T E N S I O N C O N T R O L S P E C I A L I S T SDOVER FLEXO ELECTRONICS, INC.217 PICKERING ROAD, ROCHESTER, NH 03867 USA 603-332-6150 FAX 603-332-3758E-Mail: info@dfe.com • Internet: www.dfe.com • ISO 9001 Certified
