Differential Pressure Control (FSD Series)
 Differential Pressure Control (FSD Series) |
Product Description
FSD series differential pressure control is kind of safety switch, it protects refrigeration compressor from damage of too low oil pressure of lubricating oil. If the oil pressure is too low, the controller will stop the compressor after a while.
FP74E floating-point differential pressure control is usually used in the water system of central conditioning. It controls the pressure difference between water supply pipe and return pipe. Different with other types, it is equipped with a single-pole double-throw floating-point contact.
The movement of floating-point will connect the contact plate to open or close the operating valve of motor drive. One typical application is to mount the valve on the by-pass line near the system's water pump. When the pressure difference between the system's feeding and return pipes is over the set value of the controller, the valve turns up and more water will flow through the by-pass valve and hereby reduces the pressure difference between feeding and return pipes.
