Murphy OPLC-A-600 Pressure Swichgage

The Murphy OPLC-A-600 is a robust pressure Swichgage designed for industrial applications, combining a high-visibility gauge with an integrated electric switch for monitoring and controlling pressure in engines, pumps, compressors, and hydraulic systems. Manufactured by FW Murphy, this device features a 4-1/2 inch dial for easy reading, with a range of 0-600 psi, making it ideal for oil and gas, marine, and power generation sectors. Key benefits include its durable, weatherproof Type 3R enclosure, which protects against harsh environments, and its pilot duty rating for reliable low-voltage control circuits. It offers adjustable set points via snap-acting contacts, providing both indication and shutdown protection to prevent equipment damage. Compared to similar products like those from Ashcroft or WIKA, the Murphy Swichgage stands out for its integrated switch-gauge design, reducing installation complexity and costs, though it may require periodic calibration for optimal accuracy. Drawbacks include its analog nature, lacking digital outputs found in modern alternatives. This pre-owned unit shows signs of use but remains functional for cost-effective retrofits.
