21294596 Pressure Monitor | Genuine Volvo Penta Part

🔧 Product Description

A calibrated pressure switch used by a Volvo Penta monitoring, indication or engine-protection system. Its pressure range and switching logic are application-specific and it must be selected by exact part number. High-value assembly (listed at USD 1,217.00 by Palmer Power), consistent with a monitor unit rather than a simple sender.

🚤 Compatibility

Typically suits:

• Volvo Penta D16C-A MG

• Engine Family: D

⚙️ Key Features

• Provides a discrete alarm or shutdown signal
• Factory-calibrated switching point
• Exact thread and electrical logic are application-specific
• Engine type: Volvo Penta marine or industrial engine
• 2 used per assembly

🔌 Function

Changes electrical state when the monitored pressure reaches the calibrated switching point.

⚠️ Common Signs of Failure

• False pressure warning
• Alarm does not activate during testing
• Intermittent switch operation
• Leakage through the threaded body
• Open-circuit or short-circuit condition

🛠️ Service Notes

• Depressurise the system and isolate the circuit before removing the old unit, noting the connector orientation and any adaptor or restrictor fitted behind it
• Fit the unit specified for that position; pressure ranges and signal characteristics differ, and an approximate substitute reads plausibly and wrongly
• Be sparing with thread sealant on a unit that earths through its body, and use only what the installation calls for on the sealing face or washer
• Tighten to the manual figure and no further, as these bodies distort easily and a distorted body leaks or reads badly
• Prove the reading against a known gauge or against the engine's own behaviour before trusting it, especially when it was fitted to chase an existing fault

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
