The GT transducer is basically a two stage, air-coupled rotary transformer, having precision shielded ball bearing 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, o 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 transducer’s low output impedance, high signal to noise ratio, moderate frequency range, and open winding configuration; facilitates long transducer cable runs in harsh electrical environments.
All transducer assemblies feature double shielded ball bearings, selected Mil-Grade lubricants and stainless 303 shaft inputs. All Industrial Grade Transducers (Nema 12+) feature flex-coupling isolated shaft inputs supported by dual sets of precision sealed and shielded ball bearings. The Industrial Grade construction offers high axial and radial rigidity, secured environmental protection, and extended life without compromising accuracy. The Nema 12 grade transducers exterior is available with black anodized aluminum finish (standard) or stainless steel.
Computer Conversions offers GT compatible decoder electronics as discrete modules, printed circuit card assemblies, snaptraks, readouts, and sub systems. A large variety of decoders are available to obtain virtually any position or velocity feedback criteria required. Dependent on the particular decoding technique employed; the transducer outputs may be scaled in an analog or digital format to indicate direct degrees, inched, meters, percentage, inches per second, or RPM’s etc. Direct compatibility is offered for many motion, servo, programmable, and process controllers used in industry today.
