Reverse osmosis

 
Isolation / signal splitting

 

Water App 1

 

Reverse osmosis is a water purification technology that removes larger particles from drinking water.

 

The technology works by using a high pressure pump to increase the pressure on the salt side of a reverse osmosis membrane, forcing water through the membrane while almost all (approx. 95% to 99%) of dissolved salts remain behind in the reject steam. The more concentrated the feed water, the more pressure is required to overcome the osmotic pressure.


In a reverse osmosis system, measurements like flow, pressure, and temperature are necessary, and in this case, all are measured with two-wire transmitters. The output signals from these transmitters are connected to a local control panel and the main PLC. The PR 3109 isolated converter / splitter is an excellent solution that powers the two-wire transmitters and provides high isolation between input and both outputs. This is a great replacement solution for older systems where one input is repeated using an extra analog output on the PLC. Our solution results in increased signal accuracy with superfast response time and the spare PLC analog output channels are now available for other tasks.
