HBM Releases Torque Transducer
February 14, 2011—A torque transducer integrated between drive and machine, directly in the drivetrain, is suitable for precisely determining the performance of a machine. As a metrology technology specialist, HBM offers numerous solutions to accurately and reliably measure such forces; including the type T10FH torque flanges, which come standard with nominal (rated) torques of up to 300 kNm. In order to be able to use the T10FH transducer in potentially explosive environments, the electronics have been appropriately modified and adapted. The special version of the T10FH transducer is available with ATEX approval ll 2G EEx d e q IIC T4 for nominal (rated) measuring ranges up to 150 kNm. The design for Category II2G and therefore permits application in Zone 1. Data transmission between rotor and stator is digital, so that secure, error-free measured value acquisition and transmission is possible even under difficult ambient conditions, for example electromagnetic interference or fluctuating temperatures.
A typical application for the T10FH-ATEX torque transducer is in the controlling of gas engines for gas compressor systems. These are used, for instance, in compressor stations of gas pipelines or subterranean gas caverns. As the pressure in the pipeline frequently fluctuates, a rapid and accurate regulation that reacts to changing operating parameters is essential. The drive can thus be effectively protected against damage and the fuel consumption is also reduced at the same time. Status data of the system can also be acquired due to the high accuracy of the torque measurement and can be used to ensure optimized maintenance intervals together with condition-based monitoring.
