Communication and data processing CPS41D

Communication with the transmitter

Always connect digital sensors with Memosens technology to a transmitter with Memosens

technology. Data transmission to a transmitter for analog sensors is not possible.

Digital sensors can store measuring system data in the sensor. These include the following:

• Manufacturer data

– Serial number

– Order code

– Date of manufacture

• Calibration data

– Calibration date

– Slope at 25 °C (77 °F)

– Zero point at 25 °C (77 °F)

– Number of calibrations

– Serial number of the transmitter used to perform the last calibration

• Operating data

– Temperature application range

– pH application range

– Date of initial commissioning

– Maximum temperature value

– Hours of operation under extreme conditions

– Number of sterilizations

– Resistance of glass membrane

You can display the above-mentioned data using the Liquiline CM44x, CM42 and Memobase Plus

CYZ71D.

Dependability

Reliability

Easy handling

Sensors with Memosens technology have an integrated electronics unit that stores calibration data

and other information (e.g. total operating hours and operating hours under extreme measuring

conditions). Once the sensor has been connected, the sensor data are transferred automatically to

the transmitter and used to calculate the current measured value. As the calibration data are stored

in the sensor, the sensor can be calibrated and adjusted independently of the measuring point. The

result:

• Easy calibration in the measuring lab under optimum external conditions increases the quality of

the calibration.

• Pre-calibrated sensors can be replaced quickly and easily, resulting in a dramatic increase in the

availability of the measuring point .

• Maintenance intervals can be defined based on all stored sensor load and calibration data and

predictive maintenance is possible.

• The sensor history can be documented on external data carriers and in evaluation programs, e.g.

Memobase Plus CYZ71D. Thus, the current application of the sensors can be made to depend on

their previous history.

Integrity

Data security thanks to digital data transmission

Memosens technology digitizes the measured values in the sensor and transmits the data to the

transmitter using a non-contact connection that is free from potential interference. The result:

• Automatic error message if sensor fails or connection between sensor and transmitter is

interrupted

• Immediate error detection increases measuring point availability
