In some in-line applications sensor removal for routine cleaning or calibration becomes difficult due to conduit or cabling. The 551 Quick Change Sensor offers a unique method to extract the sensor through a “Nut Lock” Adapter system. The Nut Lock Adapter threads directly into 1 inch NPT process connections. Sensor length options up to 12 inches allows the sensor to fit through flanges and stand-off piping. The 551 sensor also includes a 3/4 inch rear connection for use in submersible applications.

  • Patented design increases sensor life, accuracy and reliability
  • High resistance to poison: Reduced calibration offset error
  • Large surface area reference junction eliminates plugging issues
  • Eliminates error due to fluctuating pressure
  • No exotic gel or polymer electrolyte which may be incompatible with the process
