描述
LCt-104 Tension Transmitters measure up to four independent web points, or zones, to ensure maximum operating speeds without belt, felt, or product breakage. Each zone is precisely measured with 750,000 count resolution and produces a corresponding, high resolution, 4-20 mA output.
Total, individual, and differential outputs from two HTU transducers permit a comparison of tension signals on either side of a sheet, strip, or web. Digital calibration eliminates time consuming dead weight loading and machine ‘strapping’. With four integral operating modes, LCt-104 transmitters offer wide operating flexibility and easy installation. Simply select the mode that matches your application, enter the transducer zero and span values, and begin system operation.
When combined with HTU transducers, units measure both horizontal and vertical tension vectors. Based upon both measurements, software algorithms calculate the precise, resultant force vector and exact linear tension component. Auto-wrapping maintains smooth, constant tension for winding zones as the roll diameters increase or decrease.
