Chemical Plant Recalibrates Faulty pH Sensor
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
