SENSOR 1593219 - Caterpillar

Your engine may not have the same gauges or all of the gauges that are described. For more information about the gauge package, see the OEM information.Gauges provide indications of engine performance. Ensure that the gauges are in good working order. Determine the normal operating range by observing the gauges over a period of time.Noticeable changes in gauge readings indicate potential gauge or engine problems. Problems may also be indicated by gauge readings that change even if the readings are within specifications. Determine and correct the cause of any significant change in the readings. Consult your Caterpillar dealer for assistance.
If no oil pressure is indicated, STOP the engine. Engine damage can result.
Engine Oil Pressure - The oil pressure should be greatest after starting a cold engine. The typical oil pressure for naturally aspirated engines at rated rpm with SAE10W30 is 207 to 413 kPa (30 to 60 psi). The typical oil pressure for turbocharged engines at rated rpm with SAE10W30 is 207 to 413 kPa (30 to 60 psi).A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:
Remove the load.
Reduce engine speed to low idle.
Check and maintain the oil level.
Jacket Water Coolant Temperature - Typical temperature range is 78 to 91 °C (173 to 196 °F). The maximum allowable temperature with the pressurized cooling system at 48 kPa (7 psi) is 103 °C (217 °F). Higher temperatures may occur under certain conditions. The water temperature reading may vary according to load. The reading should never exceed the boiling point for the pressurized system that is being used.If the engine is operating above the normal range and steam becomes apparent, perform the following procedure:
Ensure the correct 50/50 antifreeze concentration.
Reduce the load and the engine rpm.
Inspect the cooling system for leaks.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load.
Tachometer - This gauge indicates engine rpm (speed). When the throttle control lever is moved to the full throttle position without load, the engine is running at high idle. The engine is running at the full load rpm when the throttle control lever is at the full throttle position with maximum rated load.
To help prevent engine damage, never exceed the high idle rpm. Overspeeding can result in serious damage to the engine. The engine can be operated at high idle without damage, but should never be allowed to exceed high idle rpm.
Note: The high idle rpm and the full load rpm are stamped on the Information Plate.
Ammeter - This gauge indicates the amount of charge or discharge in the battery charging circuit. Operation of the indicator should be to the right side of "0"(zero).
Fuel Level - This gauge indicates the fuel level in the fuel tank. The fuel level gauge is electrically operated. This gauge registers the pressure when the "START/STOP" switch is "ON".
Service Hour Meter - This gauge indicates the total number of clock hours that the
