E+H CPS11E-BA7BAA2 Orbipore pH Sensor

The ENDRESS+HAUSER Memosens CPS11E (Specific Part Code: CPS11E-BA7BAA2) is a heavy-duty digital pH sensor designed for standard industrial processes, chemical manufacturing, and water/wastewater treatment applications

 

• PS11E: Glass digital pH sensor (Memosens 2.0 technology).

• BA: Approval Type: ATEX, IECEx, and NEPSI II 1G Ex ia IIC T3/T4/T6 Ga for use in hazardous zones/explosive environments.

• 7: Application Range: Standard application (pH range: 0 to 14, temperature limits: 0 to 135°C, max pressure: 17 bar absolute).

• B: Reference System / Junction: Dirt-repellent, large-area PTFE ring junction for protection against heavy soiling and suspended solids.

• A: Shaft Length: Standard 120 mm insertion length.

• A: Electrode Type: Basic glass body version with a zero-point at pH 7.0 and an integrated NTC 30K temperature sensor for automatic temperature compensation.

    Technical Specifications

• Measuring Range: 0 to 14 pH

• Process Temperature Range: 0°C to 135°C (32°F to 275°F)

• Process Pressure Range: 0.8 to 17 bar (11.6 to 246.5 psi) absolute

• Internal Temperature Sensor: NTC 30kΩ

• Reference Lead: Ag/AgCl (Silver/Silver Chloride) with a 3 M KCl liquid reference gel

• Junction Design: Ring-shaped PTFE junction (highly resistant to clogging)

• Sensor Connection Head: Inductive, non-contact Memosens bayonet connector (IP68 rated)

• Shaft Diameter: 12 mm

• Shaft Length: 120 mm

Major System Advantages

• True Digital Plug-and-Play: True inductive signal transmission eliminates galvanic coupling errors, meaning cable submersion or moisture around the connection point does not affect reading accuracy.

• Pre-Calibration in the Lab: Because calibration data, sensor history, and total operating hours are stored directly in the sensor head chip, maintenance teams can calibrate the sensor in a clean laboratory environment and rapidly swap out the field sensor without field-recalibration.
