These tension amplifiers both interface with LVDT tension sensor or strain gauge sensors to measure tension in a continuous web strip or strand of material during converting or printing. The material can be paper, film, foil, rubber, wire, metal strip, non-woven or textiles used in continuous process. These amplifiers are ideal when you need low cost, accurate tension measurement of a web process interfaced with machine controls. Applications include input for data loggers, process controllers. Host computers or other applications that require a precise tension interface.
