1-channel pH/ORP Transmitter Liquisys CPM253

Application

The Liquisys CPM253 is a versatile pH/ORP transmitter compatible with both analog and digital Memosens sensors, designed to enhance operational safety through continuous monitoring and validation of process and sensor data. You can choose from a variety of hardware and software modules, such as relays or fieldbus communication options, to tailor the transmitter precisely to your specific measurement needs. The modular design allows for easy upgrades whenever required. With its straightforward menu system and two-point calibration, setup and operation are quick and user-friendly. The Liquisys CPM253 is suitable for use with all pH/ORP glass and ISFET sensors in non-hazardous environments, making it ideal for industries and their utilities such as:

• Chemicals
• Food & Beverages
• Power & Energy
• Water & Wastewater
• Primaries & Metals

It also supports the following communication protocols and interfaces:

• 0/4...20 mA
• HART
• PROFIBUS DP
• PROFIBUS PA

Benefits

• Enhanced operational safety: Continuous monitoring of processes, customizable alarm settings, and the trusted Memosens interface ensure reliable sensor connections.
• Reliable self-monitoring: The transmitter features a sensor check system for pH glass and reference, along with a calibration plausibility check.
• Ease of use and maintenance: The intuitive interface, hot plug-and-play capability with pre-calibrated Memosens sensors, and direct access for manual contact control simplify operation and service.
• Lower maintenance requirements: The automatic cleaning function, triggered by an alarm or limit switch, reduces the need for frequent manual cleaning (using Chemoclean).
• Versatile and adaptable: With options such as a P(ID) controller, timer, and more, the transmitter can be easily customized for a wide range of applications.
