All sensors in the system communicate with one another, and cylinders always know where they are in relation to the others. If one cylinder moves ahead, the valve will close and automatically bring it back into synchronization. Exact operations will vary depending on the specifications and configuration of your position-sensing cylinders.

2.3.4.5 Summary of Coal Mill Controls. To summarize the coal mill controls, they may be divided basically into two major categories: 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the ...

Linear displacement transducer isn't limited by stroke. March 6, 2013. One of the challenges with most linear displacement transducers (LDTs) for measuring hydraulic cylinder position is that the stroke must be known when the sensor is ordered. Furthermore, in-cylinder mounting generally requires gun-drilling the cylinder's piston …
