PTSA Sensors in Cooling Towers

PTSA sensors play a crucial role in the efficient operation and maintenance of cooling towers. These sensors serve in monitoring and controlling the concentration of treatment chemicals such as scale and corrosion inhibitors. Although there are several sensors available in the market, AlpHa’s PTSA sensor portfolio offers exemplary precision and reliability.

PSTA sensor with cooling towers
  • Minimum detection limit under 1 ppb with resolution of 0.01 ppb.
  • Automatic temperature compensation.
  • Advanced optical filtering to prevent turbidity interference.
  • Flat sensing design for flexible, non-specific in-line orientation.
  • Analog (4 – 20 mA or 0 – 5 V) or digital (RS-485 MODBUS RTU) output formats to integrate directly with third party platforms.
  • Installs directly with all existing 1″ and 3/4″ tee fittings.

How Do PTSA Sensors Work

Fluorescent trace chemicals such as PTSA change in color in response to chemical content concentration. So, when added to treatment chemicals such as scale and corrosion inhibitors, an in-line fluorometer is able to measure the changes in the PTSA. Hence, interpret the concentration of the treatment chemicals.
