FAQ
FAQ
Q1: What is the Bently Nevada 89412‑01 used for?
A1: It is a magnetic pickup (speed sensor) used to detect rotation of a ferrous target (gear, shaft, notch) and generate AC voltage pulses for speed or phase reference.
Q2: How does this magnetic pickup sensor work?
A2: It operates on the inductive principle — as a ferrous target passes the sensor’s magnetic tip, it induces a voltage pulse proportional to the relative speed of the target.
Q3: Does the 89412‑01 require external power?
A3: No — the magnetic pickup generates its own AC signal as the ferrous target passes by; no external excitation power is required.
Q4: What signal output does it provide?
A4: It outputs AC voltage pulses whose frequency corresponds to the rotational speed of the machine and whose amplitude depends on speed and target geometry.
Q5: What environments is this sensor suitable for?
A5: It is suitable for industrial environments where rotating machinery speed, phase, or vibration needs to be monitored.
Q6: What temperature range can this sensor operate in?
A6: It can operate in a wide industrial temperature range, typically from about −40 °C up to +120 °C.
Q7: How is this sensor mounted?
A7: It is typically mounted near a shaft or gear toothed wheel such that its tip faces the rotating ferrous target with a small air gap.
Q8: Are additional components needed to use this sensor?
A8: Yes — the output signal often needs to be connected to a tachometer, proximitor module, PLC input, or monitoring electronics that count frequency or convert it to speed/phase information.
