Product Introduction
Product Features
The SmartBRX angle sensor test and analysis system adopts an epoch-making angle sensor dynamic synchronization decoding framework. The system is based on modular design and can support the testing of almost all angle sensors such as resolvers, auto-aligners, differential transformers, induction synchronizers, eddy currents, optical braiding, and magnetic braiding. It is also supported by 6 turntables with 1″~15″ accuracy and 30000rpm high speed, truly realizing the unification of angle sensors from accuracy testing to high-speed dynamic testing.
Modular design: can be freely combined into multiple working modes to cope with various application scenarios.
BRX: Single-phase excitation dual-output brushless resolver.
VR: Reluctance type resolver
BRT: Two-phase excitation single output brushless resolver
RVDT: RVDT (Rotary Variable Differential Transformer) is the abbreviation of Rotary Variable Differential Transformer. It is an angular displacement sensor. It has the characteristics of infinite resolution, long service life and high accuracy, and can realize limited rotation angle measurement.
LVDT: LVDT (Linear Variable Differential Transformer) is the abbreviation of linear variable differential transformer and is a linear displacement sensor.
DoublSyn: Tamagawa Seiki's new dual-redundant rotation angle sensor, in addition to the planarity, reliability and environmental resistance of traditional VR-type resolvers, also has high accuracy, noise immunity and redundancy.
