FAQ
FAQ
Q1: What is the Bently Nevada 991-25-70-01-00 used for?
It is used to measure axial shaft displacement (thrust) and convert it into a standard 4–20 mA signal for control and protection systems.
Q2: What does the “25” represent?
It indicates the full-scale measurement range of 25-0-25 mils.
Q3: What does the “70” represent?
It indicates a 7.0 m system length configuration.
Q4: What is the output signal type?
It outputs a loop-powered 4–20 mA analog signal proportional to shaft axial position.
Q5: What mounting method is used?
It uses standard 35 mm DIN rail mounting inside control cabinets.
Q6: What is the operating power requirement?
It operates on 12–35 VDC loop power.
Q7: Is this a standalone sensor?
No. It must be used with a Bently Nevada 3300 NSv proximity probe system.
Q8: What should be checked before replacement?
Verify full-scale range, system length, mounting type, probe compatibility, and available cabinet space for installation.
