Floating Point Differenzdruckschalter

Floating Point Differential pressure switch Introduction FP74E pressure differential control is usually used in the water system of central conditioning. It controls the pressure difference between water supply pipe and return pipe.FP74E pressure differential control 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. On the opposite, the pressure differential will increase between these two pipes of the water system. FP74E pressure differential control is usually used in the water system of central conditioning.
