主要特点9/strong>
790 series was developed to accurately measure torque when the ratio of peak torque to average torque is high. In that situation a conventional torquemeter must be oversized to avoid damage a process which greatly reduces accuracy. Conditions that create high peak to average ratios include starting stopping or reversing inertial loads torsional oscillations and diesel and single cylinder engine/compressor drives. Additionally when peak torques are unknown an 790 reduces the risk of damage from unexpected or accidental torque spikes.
An 790 can accurately measure low running torque and high transient spikes without the expense of using several conventional sensors. Furthermore these products are hardened to the intense electromagnetic interference (EMI) often generated by modern IGBT-based adjustable speed drives/controls.
These torquemeters use patented technology newly refined to achieve 790 performance. Rotary transformers connect torque sensing strain gages to stationary circuitry without contact. Transformers don't generate noise or wear. They are immune to noise dirt and lubricants and provide long maintenance-free life. Unlike ferrite transformers robust non-ferrite design isn’t susceptible to cracking and impact damage. 790 sensors are suitable for diesel service and other hostile environments.
RFI shielded circuitry improved EMI tolerance and the high level output with low source impedance further enhance noise immunity. Simple cabling yields calibration and balance truly free of cable effects. There are no slip rings brushes radio transmitters or other limited-life noise-generating elements.
