Vibration Monitors - VS-1

Product catalog summary

Overview: The Electro-Sensors VS Series are compact and rugged stand-alone vibration monitors designed to protect industrial machinery from catastrophic failures due to abnormal vibration levels. They are suitable for early detection of malfunctions, enabling cost-effective preventive maintenance.

Key Features:

Adjustable vibration alarm trip-point with selectable over- or under-vibration alarm.
Adjustable alarm delay to prevent false shutdowns.
Fail-Safe output for alarm and shutdown control logic.
SPDT relay or NPN output options.
Optional 24 Vdc power supply available.
Available in NEMA 4X and explosion-proof housings.

Specifications:

Alarm Trip Point: VS1: 0.1 - 2.2 in/s rms; VS2: 2 - 26 in/s rms.
Alarm Delay: 1 - 10 seconds.
Operational Limits: Min. frequency: VS1: 10 Hz, VS2: 1 Hz; Max. acceleration: ±12 g peak (Relay), ±50 g peak (NPN).
Power Requirements: 24 Vdc (18 - 30 Vdc), 30 mA max.
Relay Type: SPDT, 5 A @ 30 Vdc or 250 Vac.
Enclosure: NEMA 4X (Cast Aluminum), XP (Explosion-proof).
Operating Temperature: NPN: -40°C to 85°C; Relay: -40°C to 65°C.
Weight: NEMA 4X: 0.75 lb; XP: 5.70 lb.

Installation: The VS Series monitors must be mounted rigidly to a smooth, flat surface with all mounting tabs/holes used to prevent resonance errors. The sensing direction arrow must be aligned parallel to the vibration axis being monitored.

Applications: The VS1 is suitable for machinery like motors, gearboxes, turbines, and pumps, while the VS2 is ideal for vibrating machinery such as conveyors and feeders.
