双量程扭矩传感器

产品简介TQ-662型转矩传感器是TQ-660系列转矩传感器的小量程形式，TQ-662型传感器是为了克服传感器旋转时的摩擦力矩而特殊设计。当量程小于5Nm时TQ-660系列转矩传感器两端的支承轴承的磨擦力就成了不可忽略的干扰因素，TQ-662型小量程转矩传感器在结构上与TQ-660型转矩传感器的不同之处在于：避免了轴承磨擦力对测量结果的影响。产品特点● 小量程设计，避免轴承摩擦力对检测的影响● 非接触无线输入输出● 稳定性好、精度高、可靠性好● 体积小、重量轻、易于安装● 可检测正反向扭矩和转速及功率● 不需反复调零即可连续测量正反向扭矩

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.
