J.R. Willis PU985-24L&-T Zero Speed Proximity Vane Pickup

The J.R. Willis PU985-24L&-T Zero Speed Proximity Vane Pickup is an industrial-grade sensor designed to monitor rotational velocity and confirm stopping conditions in demanding mechanical systems. Capable of functioning reliably with a 5 to 24 volt AC input, this unit utilizes electromagnetic principles to detect the passage of a metal vane without physical contact. It is commonly used in settings such as gas turbines and large pumps where verified motion data is mandatory for safe startup and operation cycles. When the sensor detects no vane activity, it signals a zero-speed condition which allows connected systems to engage emergency stops or prevent false engagement sequences. Providing durable performance in harsh plant environments, this pickup ensures continuous oversight of shaft position to mitigate risks associated with unmonitored downtime.
