Product Description

E+H Wall-Mounted Analyzer Liquisys CPM253-PR0005 pH/ORP Transmitter

The E+H Wall-Mounted Analyzer Liquisys CPM253-PR0005 pH/ORP Transmitter is a high-performance solution designed for continuous and reliable monitoring of pH and oxidation-reduction potential (ORP) in industrial, water treatment, and process environments. Engineered by Endress+Hauser, a leader in measurement technology, this wall-mounted transmitter combines advanced digital capabilities with robust design to deliver accurate, real-time data for critical applications. Whether deployed in wastewater treatment, chemical processing, or food and beverage production, the CPM253-PR0005 ensures operational efficiency, compliance, and long-term reliability.

Key Features and Capabilities
The Liquisys CPM253-PR0005 is engineered to meet the demands of diverse industries, offering a versatile platform for pH and ORP measurement. Its wall-mounted design simplifies installation in control rooms, outdoor enclosures, or near-process locations, while its modular architecture supports seamless integration with existing systems. The transmitter accommodates both analog sensors and Endress+Hauser's proprietary Memosens digital sensors, such as the CPS11, CPS12, and CPS71 series. This compatibility ensures flexibility in sensor selection, enabling users to optimize performance for specific applications.

With a measurement range of 0 to 14 pH and ORP from -2000 mV to +2000 mV, the CPM253-PR0005 provides exceptional accuracy: ±0.01 pH (standard) and ±1 mV for ORP, with high-precision modes achieving ±0.005 pH and ±0.5 mV. These specifications make it ideal for applications requiring tight control over chemical processes, such as neutralization reactions, disinfection monitoring, or corrosion prevention. The transmitter's ability to handle extended ranges via calibration further enhances its adaptability to challenging environments.

Advanced Digital Technology
At the heart of the CPM253-PR0005 is its support for Memosens sensor technology, which digitizes signals at the sensor level. This eliminates interference from moisture, electrical noise, and long cable runs, ensuring stable and precise measurements in electrically noisy or corrosive environments. The digital interface also enables advanced diagnostics, including sensor health monitoring, glass electrode status, and reference electrolyte depletion alerts. These features reduce unplanned downtime by predicting sensor failures and simplifying maintenance scheduling.

The transmitter features a backlit LCD display with intuitive graphical menus, allowing operators to navigate settings, calibration, and diagnostics quickly. Its user-friendly interface supports multi-language operation, catering to global users. Calibration is streamlined with 1-7 point auto-recognition buffers, minimizing manual input errors. For complex applications, the transmitter can store multiple calibration profiles, enabling rapid switching between different process conditions.

Communication and Output Options
The CPM253-PR0005 ensures seamless connectivity with industrial control systems through its 4–20 mA isolated output, HART 7 protocol, and optional Modbus via an adapter. These protocols facilitate integration with PLCs, SCADA systems, and data loggers, enabling centralized monitoring and control. Relay outputs are available for alarm functions, triggering actions such as pump activation or chemical dosing based on predefined thresholds.

Power options include a universal 100–240 V AC supply or 24 V DC (18–30 V DC range), ensuring compatibility with standard industrial power systems. The transmitter's rugged design meets IP66/NEMA 4X protection standards, safeguarding against dust, water ingress, and harsh environmental conditions. It operates reliably in temperatures ranging from -20°C to +60°C (-4°F to +140°F), making it suitable for both indoor and outdoor installations.
