Figure 3-13 Cushion System with Type "B" Integrated Valve
Section 3.4.1 Cushion Pressure Transducer Mounting
The system uses a method of control in which the fill valve or dump valve is energized to raise
or lower the pressure of the system. The pressure transducer tells the system when it has reached
the proper pressure. Because air pressure drops occur across air lines when filling or dumping,
proper placement of the pressure transducer is very important for correct operation of the system.
Possible pressure transducer mounting locations from best to worst are (refer to Figure 3.14):
a) A spare port on the cushion surge tank.
b) The same port that the safety pop-off valve is mounted on if it has its own port on the
surge tank.
c) Right at the outlet on the surge tank that goes to the cushion.
d) Right at the inlet on the surge tank from the Fill/Dump valves.
e) If there is no surge tank the pressure transducer should be mounted right at the inlet on
the cushion.
