PISTON RING SET 0878625 - Caterpillar

High Pressure Sensors
Illustration 1 g02263513
Table 1
Operating pressure 50 MPa
Supply Voltage +7V ~ +14V
Output signal 500 100 Hz (PWM)
Output range 5% ~ 95% Note: The values in Table 1 are for bench testing only. Values may not represent parameters for machine systems specifications.Tool Load Pressure
The tool load pressure sensor detects the signal of tool load pressure. The machine ECM will then control the pilot pressure using the proportional reducing valves for the attachment control valve in order to enhance synchronous operation.The squeeze function utilizes the tool load pressure sensor to control pilot pressure to the attachment control valve spools.Low Pressure Sensors

Table 2
Operating pressure 10 MPa
Supply Voltage +7V ~ +14V
Output signal 500 100 Hz (PWM)
Output range 5% ~ 95% Note: The values in Table 2 are for bench testing only. Values may not represent parameters for machine systems specifications.Hydraulic Foot Pedal
This pressure sensor is used to detect pedal operation for the tool. The signals from the sensor are sent to the machine ECM and are used for pump flow control and engine speed control. Flow Limit Pressure
This sensor measures NFC pressure of each pump, and inputs the signal to the machine ECM. The pressure information is used for flow limitation control.Boom UP Pressure
For tool systems in which the operation of combined flow from two pumps is available, this sensor detects boom UP signal. The signal changes the work tool pump operation from two pumps to one pump. This operation will enhance the synchronous operation of the work tool and the boom UP operation.Boom DOWN Pressure
In tool systems in which boom down proportional reducing valve is installed, this sensor detects signal of boom DOWN operation amount. The signal is used to throttle the spool shift pressure of boom DOWN operation according to the intensity of this pressure. This operation will enhance boom down operability in time of heavy weight tool were installed.Stick IN Pressure
For tool systems in which the proportional reducing valve for stick IN control is installed, this sensor detects signal of stick IN operation pilot pressure. The signal is used to throttle spool shift pressure of boom DOWN operation pilot pressure according to the intensity of this pressure. This operation will enhance stick IN operability in time of heavy weight tool were installed.Stick OUT Pressure
For tool systems in which the operation of combined flow from two pumps is available, this sensor detects stick out signal. The signal changes the work tool pump operation from two pumps to one pump. This operation will enhance the synchronous operation of the work tool and the stick OUT operation. Swing Pressure
For tool systems in which the operation of combined flow from two pumps available, this sensor detects a swing operation signal. This signal changes the work tool pump operation from two pumps to one pump. This operation will enhance the synchronous operation of the work tool and the swing operation.
