125800-01

The BENTLY 125800 – 01 has been engineered to offer remarkable performance attributes. Its high accuracy of ± 0.5 degrees in detecting shaft position ensures that machinery operates within optimal parameters. This precision is crucial as even the slightest misalignment in rotating equipment can lead to increased wear and tear, reduced efficiency, and potential breakdowns.

In terms of resilience, this module is built to withstand the harsh conditions often present in industrial environments. With a bandwidth of 0 to 10 kHz, it can effectively process keyphasor signals across a wide frequency range. This wide – ranging bandwidth capability allows it to adapt to different operating speeds of machinery, making it suitable for a diverse range of applications.
