Difference pressure sensor 10 m
Item no.: 2136454

The differential pressure sensor kit enables dp-c and dp-v control of the frequency-controlled high-pressure centrifugal pumps.
The sensor measures the differential pressure between the suction ports and discharge ports to the pipes, and converts this into an electrical signal 4-20 mA, which is used by the frequency converter to regulate the pressure of the pump. The value of the output current is proportional to the differential pressure.
Difference pressure sensor 20 m
Item no.: 2136456

The differential pressure sensor kit enables dp-c and dp-v control of the frequency-controlled high-pressure centrifugal pumps.
The sensor measures the differential pressure between the suction ports and discharge ports to the pipes, and converts this into an electrical signal 4-20 mA, which is used by the frequency converter to regulate the pressure of the pump. The value of the output current is proportional to the differential pressure.
Difference pressure sensor 40 m
Item no.: 2136458

The differential pressure sensor kit enables dp-c and dp-v control of the frequency-controlled high-pressure centrifugal pumps.
The sensor measures the differential pressure between the suction ports and discharge ports to the pipes, and converts this into an electrical signal 4-20 mA, which is used by the frequency converter to regulate the pressure of the pump. The value of the output current is proportional to the differential pressure.
