Futek PFT510 miniature flush mount pressure sensor for desalination system monitoring

Converting salt water into fresh water is most commonly performed through high-pressure reverse osmosis. These systems require constant pressure delivered from a system of pumps to maintain membrane health and maximise system efficiency. By incorporating a pressure sensor into a control loop control system, the pump can maintain a constant operating pressure for maximum efficiency.

Futek’s PFT510 miniature pressure sensor can be inserted between a water pump output and reverse osmosis filter input. The output signal from the pressure sensor is amplified with the company’s IAA series or IDA100 amplifier and fed into a PLC. The PLC then regulates the motor output in response to changing pressures, maintaining a constant output pressure. This increases the filter’s life and maximises system efficiency.

The IDA amplifier output can also be monitored and adjusted accordingly over USB connection with the company’s SENSIT software.
