Description:

Computer Conversions GT and HB Transducers are brushless, Electromagnetic, Rotary Sensors used to provide Precise Absolute or Incremental Position, and Velocity feedback in harsh environments. All Computer Conversions Transducers are continuous rotation, bi-directional, and electronically passive devices (no electronic components to degrade or fail), that require zero maintenance, and may be installed in virtually inaccessible locations.

The transducer is basically a two stage, air-coupled rotary transformer, having precision shielded ball bearings as the only physical contact between the casing (stator), and the rotary shaft input (rotor). The transducer biases AC signals used as inputs to either stator or rotor windings; providing outputs that are proportionate in phase, or ratiometrically proportionate in amplitude, to the angular position of the shaft. Because transformer couplings are used both to excite and retrieve data; slip rings, brushes, or contacts, are neither used or required. Without brushes; brush bounce, misalignment, and wear related problems do not exist, and infinite repeatable feedback can be expected.

The GT and HB transducer's low output impedence, high signal to noise ratio, moderate frequency range, and open winding configuration; facilitates long transducer cable runs in harsh electrical environments. The GT and HB suffixes call out different resolver electrical specifications.
