Solarhome Pressure Switch Gauge 05703110
Brand: Solarhome Store. Features include a Pressure Switch Gauge with part numbers 05703110, 20P-75, 3N2780, designed for Murphy 0-75 PSI. This unit is best for compact Murphy-based systems requiring a straightforward pressure readout with an integrated switch for alarms or control signals.
Best for: Murphy-compatible, small-scale setups where precise 0–75 PSI monitoring is needed and a simple switch action suffices. Selected for tight integration with Murphy-style equipment.
Caution: Availability and compatibility depend on matching the exact Murphy model and wiring configuration; verify your system’s switch rating and electrical requirements before installation.
Murphy by Enovation Controls 20P-100 Swichgage
Brand: by Enovation Controls. Features: Pressure-Indicating Gauge with a Built-In Electrical Limit Switch for tripping alarms or shutdown devices. This product is best for applications needing a robust, integrated alarm/shutdown mechanism on higher pressure ranges.
Best for: Industrial environments where automatic shutdown or alarm signaling is critical, and the built-in switch simplifies wiring and control logic.
Limitation: The unit’s electrical characteristics rely on compatible wiring and control circuits; ensure your control panel supports the switch’s signaling type and voltage.
MEANLIN MEASURE Stainless Steel Gauge (0–100 PSI)
Brand: MEANLIN MEASURE Store. Features: Stainless steel liquid-filled pressure gauge, 2.5″ dial, 1/4″ NPT connection, lower mount. This model is ideal for fluids exposure and vibration-prone environments, offering enhanced durability and stable readings.
Best for: Environments with potential vibration or fluid exposure where a liquid-filled gauge helps dampen fluctuations and extend service life.
Limitation: The 2.5″ dial is larger and may not fit compact panels; verify mounting clearance and thread compatibility with your system.
MEANLIN WELL PUMP Gauge 0–100 PSI
Brand: MEANLIN MEASURE Store. Features: Well Pump Pressure Gauge with 1/4″ NPT, 2″ dial face, and lower mount; includes 1/2″ NPT and 3/8″ NPT hex bushing options. This model is designed for well pump installations requiring a compact, reliable gauge with versatile mounting and connection options.
Best for: Well pump or field service setups needing reliable, slightly larger readability with flexible connection options for installation convenience.
Caution: If you require a higher accuracy or different dial size, consider alternatives in the MEANLIN line that match your exact specifications and mounting constraints.
100 PSI Oil Pressure Gauge (05703115)
Brand: Not listed. Features: Wide application; designed to fit Murphy 20P-100 and replace 05703115. Suitable for a variety of industrial and mechanical applications, with precise pressure monitoring and reliable electrical performance.
Best for: Murphy 20P-100 systems and similar equipment where a replacement or upgrade to a 05703115-type gauge is needed for accurate pressure monitoring and switch control.
Limitation: The absence of a brand name may affect availability of matching accessories or localized support; confirm compatibility with your control system before purchase.
Buying Guide
What to consider when choosing a pressure gauge with switch:
- Pressure range and dial size: Match the instrument to your target pressure range and the space available on panels or machinery.
- Mounting style: Lower mount and direct-thread options affect installation ease and vibration tolerance.
- Connection threads: Verify NPT sizes (1/4″, 1/2″, 3/8″) and the presence of adapters or bushings you may need for your equipment.
- Liquid-filled vs. dry gauges: Liquid-filled gauges dampen vibration and pulsations but may be bulkier; choose based on environment.
- Integrated switch characteristics: Ensure the switch type (electrical limit switch or alarm output), voltage, and contact configuration fit your control system.
- Compatibility: Confirm the gauge model supports the specific equipment family (e.g., Murphy 0-75 or 20P-100) and that wiring aligns with your control panel requirements.
- Durability and environment: Consider corrosion resistance, material (stainless steel if exposed to moisture or chemicals), and temperature range.
FAQ
- What is a pressure gauge with switch used for?
- Do I need a liquid-filled gauge for my application?
- How do I choose the right mounting style?
- Can I mix and match gauge and switch types?
- What installation details are important?
- Is a built-in switch always safer than a separate switch?
A pressure gauge with a switch combines a readable pressure display with an electrical switch that can trigger alarms, shutoffs, or control circuits when a preset pressure is reached.
Liquid-filled gauges are beneficial in high-vibration or pulsating environments, as the liquid dampens needle movement and extends gauge life.
Lower mount is common for well pumps and panels where front-access is limited; consider diameter and available space when selecting a mounting option.
Yes, but ensure electrical compatibility (voltage, current, and switch type) and mechanical compatibility (thread size and mounting) with your system.
Verify thread type, gasket seals, electrical wiring diagrams, and enclosure protection (IP rating) to ensure safe operation in your environment.
A built-in switch simplifies wiring and reduces potential wiring errors, but always confirm the switch’s rating and compatibility with your control system and safety standards.
