Bently Nevada - GE Digital Keyphasor mark on the shaft coincides with the Keyphasor transducer. The Machinery Protection System can accept up to four Keyphasor signals for normal configuration and up to eight Keyphasor signals in a paired configuration. Note: A Keyphasor signal is a once-per-turn or multiple-event-per-turn pulse from a rotating shaft or gear used to. Vendor List Privacy Policy. The Keyphasor is used as a reference point of the shaft, 0 to degrees.

Keyphasor is an electric pulse, or trigger, which is derived from a point on a rotating shaft, it serves as a zero phase reference for determining where imbalance is on a rotor. The keyphasor in turbo machines are necessary to find phase angle of unbalance mass at the time of dynamic balancing. Call a Calibration engineer at We're open Mo-Th 8am to pm. Schedule an On-site Visit! The Keyphasor module, PWA , is completely replaced by the updated module.För varvtalsmätning kan indata från The GE/ Bently Nevada /25 Series Enhanced Keyphasor Modules are half-height, two-channel modules used to provide Keyphasor signals to the monitor modules in a rack. The module receives input signals from proximity probes or magnetic pickups and converts the signals to digital Keyphasor signals that indicate when the Keyphasor mark on. We promise not to spam you. Applications Engineer 17 years at Instrumart.
DISCONTINUED BY MANUFACTURER, KEYPHASOR MODULE, A keyphasor is any instrument that relies on the principle of keyphasor for its operation. The keyphasor essentially times the main shaft of the machine; through this, important information about the life of the machine is generated each time the shaft rotates. As a transducer, the keyphaser has the potential to convert one form of energy to. Call for availability. Thanks for an excellent article.
16 Givarplacering Keyphasor (rpm We are measuring phase from the moment the keyway in the shaft passes the keyphasor until the vibration probe reads its maximum level. This is the top of the sine wave. The vibration proximity probe reads its maximum level when the red heavy spot passes it. In the animation below, the phase is 90 degrees. Note that one cycle of vibration – eg. Bently Nevada Headers Connector Header. The Enhanced Keyphasor Module is an improved system module. Applications Engineer 17 years at Instrumart.
Anslut en varvräknare eller Keyphasor Keyphasor configurations for any dynamic input channel through the PAV, PAS, PAA, PAD, and PVT input modules. For high-phase accuracy applications (over 12, rpm) the Keyphasor Input Module must be used. The input speed limit is , rpm and can accept input speed signals up to 1,, cpm (20 kHz). The Keyphasor Input Module can. Bently Nevada Enhanced Keyphaser Module. How does Keyphasor works?
VIBXPERT ® är The Bently Nevada Enhanced Keyphaser Module is a half-height, two-channel module used to provide Keyphasor signals to the monitor modules in a rack. The module receives input signals from proximity probes or magnetic pickups and converts the signals to digital Keyphasor signals that indicate when the Keyphasor mark on the shaft coincides. You can unsubscribe at any time. The Keyphasor transducer is typically a proximity probe recommended for permanent installations in which the probe observes a physical gap change event , an optical pickup used for temporary installations in which the pickup observes a change in reflectivity event or a magnetic pickup.
