Problem

  • Growing deviation between the values of two pH sensors 

Measurement Tags Alerted

  • pH tags

How SAM GUARD Helped

  • SAM GUARD alerted operators to the deviation between the values of pH sensor A and pH sensor B, which should be close to identical
  • The gap between the two sensor readings grew over a period of time
  • The engineer checked both sensors and found that one of them was out of calibration. The engineer recalibrated the sensor. 

Value

  • Eliminated potential environmental damage as a result of improper pH control of scrubber
