1) temperature measuring device in the fuel tank, lubrication pump, the import and export of the cooler, it is important bearings and other components into the installation of temperature measurement devices and display control devices such as mercury thermometers, thermocouples and contact thermometer, you can see these parts in a timely mannerchanges in temperature.

2) pressure measuring device installed in the lubrication pump at the outlet of the filter inlet and outlet at the other parts of a pressure gauge to observe the pressure change. Differential pressure alarm is also necessary to install an alarm signal when the differential pressure is too high.

3) The oil flow measuring device in the tank equipped with oil standard oil level indicator, flowmeter or flow monitoring observation flow meter to be installed in the pipe.

Usually in the centralized lubrication system for the control system can be adjusted to take into consideration the lubrication cycle time, and to the oil time, and a display and control the lubricant supply is insufficient or excessive lubrication pump overload situation.
