    Tips: Application of torque sensor in Lift Bridge

    1. Vertical Lift Bridge
      The mechanical rework and painting of the vertical lift bridge will probably change the weight of the mobile span. At this moment, in order to ensure the normal and safe operation in the later period, checking the balance between the span and weight is quite essential. How to check the entire balance of the balance weight cable system? A big cable can be used to connect the span with the counter weight through the pulley driven by the motor on each corner of the bridge. The torque is measured on the four drive shafts at the same time, so as to confirm if the four corners have any imbalance. Through the torque sensor and the remote telemeter connecting to each drive shaft, the torque data will be recorded in lifting and lowering the span. Through comparing the lifting torque and lowering torque, and correcting the friction, it can be proved that the movable span is slightly heavier than the combined counter weight (required condition), and all four corners are in the acceptable balance scope.
    2. Two-leaf open bridge
      The Park Street Bridge in Alameda County, California is a four-lane, two-leaf open bridge spanning 372 feet. It is located between City of Alameda and Oakland.
      When the rework structure changes the weight of the original elevator, the engineers of Alameda County need to determine the appropriate counterweight to prevent the elevator drive motor from overloading. By measuring the torque on the main pinion shaft used to lift the bridge, the drive load can be easily determined and optimized by adjusting the counterweight on each span. The strain gauge of the torque sensor is connected with the pinion drive shaft and two wireless torque telemetry systems are used to simultaneously transmit strain gauge signals from the two pinions as the shaft rotates.
      Alameda County has many movable bridges. Because of repair or other mechanical changes, they are occasionally in need of adjustment. Using the wireless torque sensor remote equipment can quickly and accurately conduct torque and balance measurement, eliminate the suspected and potential problems of motor driver overload.

    Yes, we do.
    I am looking forward to buying 4 torque sensors.
    I am looking forward to buying 4 ATO torque sensors (0-5Nm), output  /-5V, and looking at the user manual. On the last page, I have pin 7 (RPM ) and 8 (RPM-) to read the machine speed in RPM. Could you please tell me what the voltage levels in these pins are? How should I read these pins with my microcontroller to compute the machine speed? Thank you!

    1. The voltage level in these pins is 5V.
    2. The single-chip microcomputer can use counters or external interrupts to read speed signals.
    We recommend that the single-chip microcomputer add optical coupling isolation to reduce interference.
