Application

The 2800 is a safety shutdown device which senses oil pressure or other control pressure. The device is typically connected to an engine fuel rack governor or fuel pump stop lever and should a loss or drop in oil pressure occur below the set point, the 2800 will trip immediately.

This unique device requires no external power source.

The 2800 can also be coupled with a wide array of devices for monitoring pressures, temperatures or other variables on rotating machinery, or can operate as a stand-alone oil pressure sensor.

Model 2800 is ideal for use on engines in both hazardous and industrial applications where positive reliability is paramount.

Operation

Model 2800 may be used alone or as the engine shutdown component in an engine monitoring system.

Model 2800 is a snap acting device monitoring low lubricating oil pressure or other control pressure. An emergency stop handle and a trip pressure adjusting screw are standard. Factory set to trip at 10 psi (0.7 bar) and field adjustable, from 5-40 psi (0.35-2.8 bar).

A trip Lever is installed on a splined shaft, and can be clamped in any of 36 radial positions to facilitate installation in most applications. The lever permits mechanical linkage between the tripping unit and the engine governor control, fuel pump stop lever or other mechanism. Pre drilled holes give a wide range of connection options. A standard Reset Latch is supplied. The Reset Latch locks the trip lever in the "run" position until oil pressure is up to normal operating pressure, then the latch releases thus arming the device.
