Patent pending HTU Web Tension Transducers provide the ultimate in web tension accuracy. With HTU transducers, there is no need to choose between a horizontal or vertical load cell. Unique SR-4 Strain Gage design places two independent wheatstone bridges on each end of the transducer. This configuration produces both horizontal and vertical force output signals; its like getting two load cells in one package. A single BLH instrument receives both signals and calculates the precise web tension force. Measuring web tension force in this manner ensures constant, dynamic accuracy, even if wrap angles change during operation.
With an ultra-low height of only 1.45 inches, HTU installation is negligible to the overall system in-line profile. In addition to low profile, units function flawlessly at temperatures from 0 to 250F. Cylindrical sensing sections are metal to metal sealed and meet or exceed all IEC IP67 requirements.
