Description

MURPHY VS2EXR-24 Shock Switch

Product Dimensions：

The Murphy VS2EXR-24 is a high-performance, explosion-proof shock and vibration switch designed to protect industrial machinery from damage caused by excessive kinetic energy. It is specifically engineered for hazardous environments.

## Product Overview

The VS2EXR-24 is a sensitive vibration monitor that triggers an internal snap-switch when vibration levels exceed a predetermined set point. Unlike standard models, the “EXR” series features an explosion-proof housing and a remote reset capability, allowing operators to reset the device from a control panel using a 24VDC pulse.

## Technical Specifications

## Key Advantages

• Precision Protection: Detects subtle changes in vibration to prevent catastrophic mechanical failure.

• Explosion-Proof: Certified for use in volatile atmospheres where flammable gases or dust are present.

• Remote Reset Efficiency: The 24VDC solenoid allows the switch to be reset without a technician having to physically enter a hazardous or hard-to-reach area.

• Gold-Plated Contacts: Often utilized to ensure reliable switching even in corrosive environments or low-current applications.

• Weatherproof Design: The rugged gasketed housing ensures the internals remain dry and functional in outdoor or wash-down conditions.

## Important Considerations (Usage Notes)

• Mounting Orientation: For maximum sensitivity, the switch should be mounted in a plane that aligns with the expected direction of vibration.

• Sensitivity Tuning: Start with a high sensitivity setting and gradually “dial it back” during normal machine operation until the switch stops tripping under standard loads.

• Wiring Safety: Ensure all conduit runs are properly sealed according to local electrical codes for hazardous locations to maintain the explosion-proof integrity.

• Maintenance: Periodically test the trip mechanism to ensure the latch hasn’t become seized due to environmental debris or lack of use.

## Typical Applications

The VS2EXR-24 is commonly found in heavy industrial sectors, including:

• Oil & Gas: Reciprocating engines, compressors, and pump jacks.

• Power Generation: Cooling tower fans and large generators.

• Water Treatment: Large centrifugal pumps and mixers.

• Mining: Shakers, crushers, and conveyor drive systems.
