DABECO P9.3 High Temp PAA Sensor

Product catalog summary

Overview: The P9.3 indicator is designed for measuring peracetic acid in various water treatment applications, including bottle washing machines and CIP plants. It supports both analog and digital output systems and is compatible with tensides and conductivity acids.

Specifications:

Measuring System: Membrane-covered, amperometric 2-electrode system.
Output Options: Analog, digital, and mA versions with varying degrees of galvanic isolation.
Measuring Range: Varies from 200 ppm to 20000 ppm, with accuracy dependent on calibration and conditions.
Temperature Range: 0 to +60 °C for measuring water, 0 to +55 °C for ambient temperature.
Pressure: Max 0.5 bar without retaining ring, 1.0 bar with retaining ring in TARAflow FLC.
Flow Rate: 15-30 L/h in TARAflow FLC.
pH Range: 1 to 8.

Performance:

Run-in Time: Varies by measuring range, from 30 minutes to 3 hours.
Response Time: T90 is approximately 3.5 minutes at 10 °C and 45 seconds at 50 °C.
Calibration: Required at the device by analytical determination.
Interferences: O3 and ClO2 increase measuring values, while H2O2 has a low influence.

Maintenance and Storage:

Maintenance: Regular signal checks, membrane cap changes annually, and electrolyte changes every 3-6 months.
Storage Conditions: Sensor dry at +5 to +40 °C, electrolyte in original bottle at +5 to +35 °C.

Technical Data:

Analog Output: Various models with different measuring ranges and resolutions, requiring specific voltage supplies and connections.
Digital Output: Modbus RTU with no terminating resistors, requiring specific voltage supplies and connections.
4-20 mA Output: Available with 2-pole terminal or 5-pole M12 plug-on flange, requiring specific voltage supplies and connections.

Spare Parts: Includes membrane caps, electrolytes, emery, and O-rings, with specific part numbers for ordering.
