Digital pH sensor for the food and beverage industries

SMARTSENS PH 8570 pH Sensor
  • pH sensor with offline calibration function
  • 2-wire loop powered sensor with integrated transmitter technology
  • Robust sensor design for SIP/CIP

SMARTPAT analytical sensors from KROHNE are the first and only line sensor in the market with integrated transmitter technology. The complete circuitry is miniaturised and fits into the sensor head. This technical achievement cuts the price in half compared to all measurement systems without integrated transmitter technology.

KROHNE is the only company who offers a real open standard without additional external transmitter and with a direct connection via standardised fieldbus from the sensor to the process control system. The SMARTPAT sensor stores all data and sends these as bidirectional digital signals with 4...20 mA / HART® 7 protocol to the control and asset management systems, handhelds, PC and other peripherals.

The SMARTPAT PH 8570 meets all requirements of the food and beverage industries.
