Why Engineers Specify This Model
- Memosens Digital Sensor Technology – Inductive, galvanically isolated connection eliminates moisture-related signal errors; sensor data (calibration history, operating hours) stored on-chip
- Plug-and-Play Sensor Exchange – Pre-calibrate sensors in the lab; swap in the field without recalibration downtime
- Guided Calibration Wizard – Step-by-step on-screen prompts reduce operator error and ensure GMP/GLP documentation compliance
- Dual-Output Flexibility – 4–20 mA HART plus configurable relay outputs for alarm, dosing pump control, or PLC integration
- Compact DIN-Rail / Panel Form Factor – Fits standard control cabinet cutouts; saves panel space vs. larger multi-channel units
- Robust IP65 Enclosure – Withstands washdown environments in food, pharma, and outdoor installations
Complete System Bill of Materials
For a fully operational pH/ORP monitoring loop, the following components are typically required alongside the CPM223-PR0005:
- Memosens pH Sensor (e.g., Endress+Hauser CPS11D or CPS71D)
- Memosens ORP Sensor (e.g., Endress+Hauser CPS12D) – if ORP measurement needed
- Process connection / immersion assembly (e.g., Endress+Hauser CPA250 or CPA450)
- Cable glands and conduit fittings (M20 × 1.5)
- 24 V DC power supply or 100–230 V AC feed
- 4–20 mA signal cable to PLC/DCS analog input card
- Buffer solutions pH 4.01, 7.00, 9.21 for calibration

Application-Specific FAQ
Q: Can the CPM223-PR0005 work with non-Memosens (analog) pH sensors?
A: No. The CM223 platform is designed exclusively for Memosens digital sensors. For analog sensor compatibility, consider the Endress+Hauser CPM253 or CPM82 series.
Q: Is this unit suitable for hazardous area (Ex) installations?
A: The base CPM223-PR0005 order code is for safe-area use. ATEX/IECEx variants require a different order code suffix — contact us to confirm the correct Ex-rated model for your zone classification.
Q: What is the calibration interval for this transmitter?
A: The transmitter itself does not require periodic calibration; only the connected pH/ORP sensor does. Sensor calibration frequency depends on process conditions — typically every 1–4 weeks in aggressive media, or every 1–3 months in clean water applications.
Q: Can I integrate this with a Siemens or Rockwell PLC?
A: Yes. The 4–20 mA output connects to any standard analog input card. HART communication is also supported for asset management integration via HART modem or HART-capable I/O modules.
Q: Does Konmask provide commissioning support?
A: We provide pre-sales technical consultation and documentation. On-site commissioning services are available through our partner network — contact us for details.
