Installation Guidelines
Follow these steps to install your Bently Nevada 200150-07-05 accelerometer correctly.
Prepare Mounting Surface – Clean and flatten the mounting area on the machine.
Install the Stud – Screw the 3/8-24 to 3/8 NPT stud into the machine first.
Tighten the Stud – Use the 3/4 inch hex feature at 2.7 to 6.8 N•m torque.
Attach Accelerometer – Screw the 200150-07-05 onto the 3/8-24 stud threads.
Connect the Cable – Attach a compatible Bently Nevada accelerometer cable.
Verify Polarity – Ensure SIG+ connects to positive input on the monitor.
Apply Excitation – Provide 4.7 to 5.5 Vdc to the accelerometer.
Check Bias Voltage – Verify output bias is +2.5 ± 0.23 Vdc before use.
Do not exceed 6.8 N•m mounting torque. Overtightening may damage the accelerometer or stud threads.
