The Murphy 45APE-S-600-EX is a specialized pressure gauge designed for industrial applications that require both pressure measurement and switching capabilities. It's particularly suited for hazardous locations
due to its explosion-proof certification. This instrument combines a mechanical gauge for visual pressure indication with two adjustable SPDT switches that can be used for various control functions.
Key Features and Specifications
Pressure Range: 0-600 psi
Switches: Two SPDT (Single Pole Double Throw) switches
Accuracy: ±1.5% of full scale
Switch Point Accuracy: ±1.5% of full scale
Enclosure: Explosion-proof, suitable for hazardous locations
Material: Stainless steel construction for durability
Mounting: Panel mount
Connections: Electrical connections for switches and process connection for pressure measurement
Advantages
Versatility: Combines pressure measurement and switching in a single device.
Accuracy: Provides precise pressure readings and switch points.
Durability: Built with stainless steel for long-term use in harsh environments.
Safety: Explosion-proof certification ensures safe operation in hazardous areas.
Customization: Adjustable switch points allow for tailored control applications.
Precautions
Installation: Ensure proper installation according to the manufacturer's instructions.
Calibration: Regular calibration is recommended to maintain accuracy.
Environment: Avoid exposing the gauge to excessive vibration or corrosive substances.
Wiring: Correctly wire the electrical connections to prevent damage or hazards.
Maintenance: Periodic inspection and cleaning are necessary to ensure optimal performance.
Applications
The Murphy 45APE-S-600-EX is widely used in various industries, including:
Oil and Gas: Monitoring and controlling pressure in pipelines and processing equipment.
Chemical Processing: Controlling processes that involve hazardous materials.
Power Generation: Monitoring pressure in boilers and turbines.
Manufacturing: Controlling pneumatic and hydraulic systems.
How it Works
The gauge uses a Bourdon tube mechanism to measure pressure, which is then indicated on the dial.The two SPDT switches can be adjusted to activate at specific pressure levels. When the pressure reaches the
set point, the corresponding switch changes state, allowing it to control external devices or systems.
Additional Features
Switch Reset Deadband: Approximately 10% of full scale.
Pressure Relief Disc: Back of case (except EX models).
Dimensions: 10 x 9 x 6 inches (254 x 229 x 152 mm) approximately.
Conclusion
The Murphy 45APE-S-600-EX is a reliable and versatile pressure gauge that offers both accurate measurement and control capabilities. Its explosion-proof design makes it ideal for hazardous environments,
while its adjustable switches provide flexibility in various applications. By understanding its features and precautions, you can effectively utilize this instrument in your industrial processes.
