Power Plant
Stable pH reading in low conductivity and ion weak samples are typically difficult to achieve. Hamilton offers 3 types of sensors for these difficult conditions.




Heat Exchangers


Heat exchangers remove the heat at various points in the process.

pH Sensors for Heat Exchangers



Goal of Measurement:
Measure to monitor functionality of heat exchanger (no leakage). In case of an ammonia-based heat exchanger a leakage is easily detected as pH decrease through ammonia entry into boiler feed water.

Range: Resolution: Interference: Sensor Type: Armatures:
pH 6 to pH 8 0.1 pH None POLILYTE PLUS
POLILYTE PLUS ARC

Other Conditions: Applications: Benefit of Sensor:
None N/A Robust measurement of pH, also in low conductive environments. Low wear out of reference system and glass.

Conductivity Sensors for Heat Exchangers



Goal of Measurement:
Measure to monitor functionality of heat exchanger (no leakage of water into ammonia) In case of an ammonia-based heat exchanger a leakage of boiler feed water into ammonia is detected as strong conductivity increase.
