Liquisys M CPM223/253
pH/ORP Measurement
Transmitter for analog and digital glass and ISFET sensors
The modular design of the Liquisys M CPM223/253 allows easy
adaption of the transmitter to a variety of customer
requirements. Starting with the basic version for "measurement
and alarm generation", the transmitter can be equipped with
additional software and hardware modules for special
applications. These modules can also be retrofitted as required.
Application
• Effluent treatment
• Neutralization
• Detoxication (electroplating)
• Water treatment
• Water monitoring

Function and system design
Features of the basic version
pH and ORP value measurement
This is selected via the menu. During measurement, the value measured can be displayed in the other
measuring mode (e.g. pH - mV or ORP % - ORP mV). The temperature is displayed at the same time or, if
desired, not shown at all.
Calibration
pH electrodes are normally calibrated with the same pH values. Therefore the transmitter presents the settings
from the previous calibration as defaults for the next calibration. If the buffer solutions are interchanged by
accident (e.g. pH 4 buffer first, then pH 7 buffer instead of pH 7 first and then pH 4) the plausibility check
ensures that the calibration is accepted anyway.
Configuration
Different alarms are required depending on application and operator. Therefore the transmitter permits
independent configuration of the alarm contact and error current for each individual error. Unnecessary
or undesirable alarms can be suppressed in this manner. Up to four contacts can be used as limit contacts
(also for temperature) to implement a P(ID) controller or for cleaning functions.
Direct manual operation of the contacts (bypassing the menu) provides quick access to limit, control or
cleaning contacts, permitting speedy correction of deviations.
Additional functions of the
plus package
Current output
In order to output wide measuring ranges while still achieving a high resolution in specific ranges, the current
output can be configured as required via a table. This permits bilinear or quasi-logarithmic curves, etc.
Sensor-Check-System (SCS)
The sensor check system alerts to deviations of the pH glass impedance or reference impedance (analog sensors
only) from the normal range, thus indicating possible failure due to pH electrode blocking or damage.
In addition, the SCS detects glass breakage of glass electrodes and leakages of ISFET sensors.
Live-check
The live check issues an alarm when the sensor signal does not change over a defined period of time. This may
be caused by blocking, passivation, separation from the process, etc.
Neutralization controller
A special control response that cannot be handled adequately by a P(ID) controller is required to neutralize
solutions. For this reason, the transmitter provides a special neutralization controller function by combining
two P(ID) controllers.
Current input
The current input of the transmitter allows two different applications: controller shut-down in case of lower
flow rate violation or total failure in the main flow as well as feedforward control. Both functions are also
combinable.
