Speed Control of Blower Using Pressure Transmitter

Posted in: , on 25. Mar. 2015 - 14:43

Dear Sir,

We need to control the blower speed centralised vacuum system based on the number of openings at a time by pressure transmitter. Each opening has a pressure transmitter, if I open one point the blower will be in initial speed, If I open the second point the speed should be increased by vacuum.

(we need to control the speed by giving signals from pressure transmitter to PLC and VFD)

Is this possible?

Please give me some relevant ideas for this process.

Best Regards,

MOHAN.P

Blower Issues In Suction Service

you can forget that idea simply because the pipe has to be the proper size for the load

intended period.

There is no way to get around the need for a greater pipe inside diameter

for the pressure gradient needed for X+ numbers of suction ports.
