For the web tension measurement in machines with limitedinstallation space the force sensor BZL-A offers great constructive advantages due to its particularly slim, compact design.The pillow block web tension bearing BZL-A made of high-strength aluminum consist primarily of a pillow block with a measuring inner part with a precision bore for a self-aligning ball bearing. The inner part component contains a double beamtechnology system with the well-known advantages of a goodlinearity and a high stiffness. The strain gauges wired as full bridge deliver a signal proportional to the force.HAEHNE offers for all its sensors a corresponding range ofamplifiers to condition the measuring signal and deliver the bridge voltage supply.
