The Liquisys CPM253 is a standard pH/ORP transmitter for analog and digital Memosens sensors. Thanks to continuous plausibility checks and checks of the measuring process and the sensor, it increases operating safety. Whichever hardware and software modules are selected, e.g. relays and bus communication, it adapts perfectly to the measuring task. It also allows the transmitter to be upgraded at any time, and its simple menus and factory calibration make configuration and operation fast and convenient.
Benefits
Higher operating safety: continuous process check system, user-defined alarm settings and an optimized Memosens interface for reliable sensor connection.
Reliable self-monitoring: sensor check system for pH electrode calibration and calibration plausibility check.
Easy to operate and maintain: intuitive user interface, precalibrated Memosens sensors with hot plug support and direct manual contact control.
Reduced maintenance effort: automatic cleaning triggered by alarms or limit switches (using Chemoclean).
Suitable for a wide range of applications: various extension options, such as P(ID) controllers, timers, etc., for flexible use in all processes.
Application areas
The Liquisys CPM253 transmitter can be used with all pH/ORP glass electrodes and ISFET electrodes in non-hazardous areas, and is suitable for the following industries and applications:
Chemical
Food & Beverage
