Murphy Low Pressure Gauge

The 20 Series (2 inch/51 mm dial) model is diaphragm-actuated, pressure-indicating gauges, with built-in electrical switches. These switches are used for tripping alarms and/or shutdown devices.

The 20P7 model includes a front, semi-automatic lockout for startup override. This built-in device holds the pointer away from the contact on startup. When pressure exceeds the set point, the lockout is automatically disengaged.

The gauge mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument. Accuracy and protection from moderate over pressure is assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning. The gauge pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts are grounded through the SWICHGAGE® case and have self-cleaning motion to ensure electrical continuity and have internal snap-acting SPDT switches.

Description

A Low Pressure Safety Gauge is a specialized pressure gauge designed to monitor and display low pressure levels in fluid or gas systems. It is commonly used in irrigation, plumbing, and industrial applications to ensure safe and optimal operating conditions by providing precise pressure readings for low-pressure ranges.


Key Features:

  1. Low Pressure Range:
    • Specifically calibrated for measuring lower pressure levels, typically in the range of 0-15 psi, 0-30 psi, or similar ranges depending on the application.
  2. High Accuracy:
    • Provides precise readings, which are critical for systems that operate within a narrow pressure window.
  3. Safety Design:
    • Features a durable housing and safety glass to prevent damage or accidents in case of overpressure or mechanical failure.
  4. Corrosion-Resistant Materials:
    • Constructed with materials like stainless steel, brass, or corrosion-resistant plastic to withstand exposure to water, air, or chemicals.
  5. Clear Display:
    • Often includes a large, easy-to-read dial or digital display to provide clear pressure readings.

Common Applications:

  1. Irrigation Systems:
    • Monitors pressure in drip irrigation or low-pressure sprinkler systems to ensure consistent and efficient water delivery without damaging emitters.
  2. Hydraulic Systems:
    • Ensures that low-pressure hydraulic systems operate within safe limits.
  3. Gas Systems:
    • Used in systems that handle low-pressure gases, such as natural gas, air, or steam.
  4. Industrial Processes:
    • Monitors pressure in processes that require precise low-pressure control, such as chemical mixing or low-pressure fluid transfer.
  5. Pump Monitoring:
    • Installed near pumps to check suction or discharge pressures in systems that operate at low pressure.

Benefits:

  1. Prevents System Damage:
    • Alerts operators to pressure fluctuations, helping to avoid overpressurization or underpressurization that could harm equipment.
  2. Ensures Efficiency:
    • Allows for precise pressure monitoring to optimize system performance.
  3. Enhanced Safety:
    • Protects against potential hazards by providing early warnings of pressure anomalies.
  4. Durability:
    • Designed for rugged environments and continuous use, ensuring long-term reliability.
  5. Ease of Installation:
    • Can be easily integrated into existing systems via threaded or flanged connections.

How It Works:

  1. Pressure Sensing:
    • The gauge detects the system pressure through a diaphragm, bourdon tube, or similar mechanism.
  2. Display Output:
    • Converts the sensed pressure into a readable value displayed on a dial or digital screen.
  3. Safety Monitoring:
    • Operators use the displayed pressure to ensure the system remains within its safe operating range.

Key Considerations:

  1. Pressure Range:
    • Choose a gauge with a range that matches the system’s operating pressure to ensure accuracy.
  2. Connection Type:
    • Ensure compatibility with the system’s connection, whether it’s threaded, flanged, or quick-connect.
  3. Durability:
    • Select a gauge with materials suitable for the operating environment, especially if exposed to corrosive fluids or extreme weather.
  4. Maintenance:
    • Regularly inspect and calibrate the gauge to maintain accuracy and reliability.

In summary, a Low Pressure Safety Gauge is an essential tool for monitoring and maintaining low-pressure systems in irrigation, industrial, and gas-handling applications. Its accuracy, durability, and safety features make it invaluable for ensuring system efficiency and preventing equipment damage
