GE-511 series differential pressure controller is an adjustable differential pressure control product. This product is designed and developed by ayt company in the United States and assembled and produced by ayt company in Hong Kong. The product is similar to ue24-01 and Dwyer dxw-11-153 series differential pressure switches, and can be used instead of each other.
1、 Selection of installation location
The proper pressure measuring position of the differential pressure switch is very important to ensure the accuracy of the pressure difference measurement value and avoid the blockage of the connecting pipe of the differential pressure switch. If necessary, the pressure tap should be placed on the upper part of the pipe along the water flow direction and a 60 mesh filter screen should be set to avoid the blockage of the pressure tap by sewage. When installing, it should be as close to the inlet and outlet of the filter, HVAC heat exchanger and fluid pump as the pressure tap.
The installation position of the differential pressure switch shall be considered to avoid the connection copper pipe of the differential pressure switch from frost crack when the outdoor temperature is low in winter. If necessary, the water pipe and copper shell connecting the differential pressure switch shall be insulated and the electric heating wire shall be added.
4. The connecting pipe is closely connected with the 1 / 4 "interface of the differential pressure switch. The copper interface and connecting copper pipe are insulated with 10 mm thick rubber and plastic insulation board and insulation pipe. The connecting pipe can also be evenly wound by electric heating line one by one, and the electric heating line is interlocked with anti freezing control. The connecting pipe with electric heating line is tightly wrapped with insulation tape, which can prevent the connecting pipe from frost crack.
3. If the set pressure difference is specified with AIT in advance, we can provide factory calibration service and print the calibration value on the nameplate to avoid inaccurate adjustment by users without professional instruments.
