490A: Torque Transducer

The 490A series of isometric torque transducers are a series of rotational load cells that are designed primarily to enable in-vivo contractile measurements made across the joints of various animal models. The 490A is an excellent choice for basic isometric measurements such as twitch, tetanus, force-frequency and fatigue when cost or throughput is a major consideration. Each torque transducer model is capable of measuring applied torque in both clockwise and anti-clockwise directions. The torque sensor heads are exceptionally durable, yet still offer the same low compliance and sensitivity as our motorized 300 series.

There are six models in the series with the most sensitive model featuring a resolution of 0.005mN-m, and the largest model having a maximum torque threshold of 100N-m. The range of sensor heads allows researchers to measure limb torque from mice up to animals as large as dogs and swine, among others. Sensor heads will mount interchangeably on all models of apparatus designed for in-vivo measurements (809/806/807/890). Each sensor is compatible with the same controller, which allows researchers to easily substitute in an appropriate sensor head for the animal model being measured.
