Model 1911/1991 Static Torque Transducers Features - strain gauge technology - range from 100 Nm to 1000 Nm - accuracy up to 0.1 %fs - mild steel with nickel plated treatment (1911) 17-4PH construction (1991) - protection grade IP 66 Applications - torque wrench and torsion measurement of shaft Description Based on BCM’s advanced strain gauge technology, 1911/1991 static torque transducers are made from either alloy steel (1911) or stainless steel (1991) and sealed to IP 66 protection grade. 1911/1991 static torque transducers are operated in the following way: one side of the transducer is fixed as the stationary part, while the other side is as motion part which intends to have torsion shift corresponding to the stationary part. These transducers are designed for symmetric use, i.e., use in measuring torques in both directions: clockwise (positive torque) and anti-clockwise (negative torque). 1911/1991 torque transducers can measure torque ranges from 100 Nm to 1000 Nm with an accuracy up to 0.1%fs. On request, these transducers can be supplied as transmitters with conditioned signals such as 0~5 V can be obtained by integrating a signal conditioner PCB in the torque body. 1911/1991 torque transducers are widely used in torque wrench and torsion measurement of shaft.
