TECHNICAL BULLETINwww.dfe.com controlling process tensionTrueTension TI17C and TI18C Amplifier/ IndicatorComparing Output Voltage Over Time at Ambient and Cycled TemperatureThe TI17C and TI18C tension indicators have hadtheir internal components upgraded andruggedized over previous generations oftension measurement electronics.140Thorough testing shows that they deliverexceptional output stability, accuracy and120signal integrity.100The charts displayed here represent datacollected from two controlled laboratory80tests that DFE's Engineering department60performed on both the TI17C indicatorand a major competitor's top-of-the-line40tension amplifier. The first chart showsthe TI17C's signal output at a constant20low-voltage input and 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)0.010-0.01-0.02-0.03-0.04-0.05-0.06-0.07-0.08Tension Amplifier OutputOver Time at Ambient TemperatureTI17C vs Major Competitor (Brand 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 and back). The drift in the DFE outputsignal is virtually non-existent at the millivolt level.The drift of the competitor brand output tracksalmost inversely with the change in temperature.While the most visible upgrade from the TI17Bgeneration is the time-saving Quick-Cal pushbuttonzero and calibration feature, design elementsthat strengthened the amplifier's outputcharacteristics include integrated isolation, circuitstabilization,noise protection, surge protection, andcurrent limiting. The TI17C retained the footprintand connector pinout scheme from the TI17B forbackward compatibility and drop-in replacement,and the board architecture and components havebeen upgraded substantially. The TI17C and TI18CTI17CBrand Xindicators are CE-marked and providedrift-free linear performance over a widerange of industrial conditions.Additional TI17C and TI18C features: Quik-Cal Zero and calibrationpushbuttons for faster setup out-of-theboxwith no pot adjustments. 0-10VDC isolated output proportionalto tension. 4-20mA isolated outputoptional.Tension Amplifier Outputand Temperature Cycle over TimeTI17C vs Major Competitor Brand1.522.533.544.555.566.577.588.599.5Time (hours)1010.511CHART 2Dual Calibration.11.51212.513Temp (degrees F)TI17C (VDC)Brand X (VDC) Tension 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
