Robertshaw 6001-201 Vibra Switch

The Robertshaw 6001-201 Vibra Switch is a high-performance vibration detection switch designed to protect rotating machinery such as pumps, fans, and cooling towers from catastrophic damage. Housed in a rugged NEMA 4 weatherproof enclosure, this unit is engineered to sense destructive vibrations and trigger a shutdown or alarm before mechanical failure occurs. This model features a 15-second startup delay, which is critical for industrial applications where momentary high vibration is normal during initial motor acceleration. By utilizing a manual reset mechanism and an adjustable sensitivity range of 0 to 4.5G, technicians can fine-tune the acceleration-sensitive trigger to match the specific harmonic profile of their equipment. The single-pole double-throw (SPDT) contact configuration ensures reliable load-side integration for critical safety circuits. With a temperature rating of -40°F to 200°F, this industrial vibration monitor maintains precision in extreme mechanical environments without drifting or false-tripping during heavy-duty cycles.

Key Technical Benefits

• NEMA 4 Rated Protection: Cast aluminum housing provides superior resistance to dust and moisture ingress in outdoor HVACR installations.
• Integrated Start Delay: The 15-second thermal delay prevents nuisance trips during high-inertia startup periods.
• Broad Frequency Response: Effectively monitors vibration frequencies from 0 to 300 Hz for comprehensive machine health monitoring.
• Field-Adjustable Sensitivity: Allows for precision calibration to accommodate varying machine loads and foundation types.
• Direct Mechanical Sensing: Uses a magnetic latching system to ensure reliable operation without the need for external power to the sensing element.

Common Questions

How do I calibrate the sensitivity on the 6001-201?
Calibration involves rotating the internal setpoint screw to find the trip point during normal operation, then backing off the setting to provide a buffer for standard operating harmonics.

Can this unit be mounted in any orientation?
For peak accuracy, the vibration trip switch should be mounted on a vertical surface so the sensitive axis is aligned with the direction of the vibration being monitored.

Is the startup delay adjustable after installation?
The 15-second delay is a fixed thermal element integrated into the 6001-201 Vibra Switch circuitry to ensure consistent timing during the motor start-up sequence.
