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 using external storage media and 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

Safety

Maximum process safety

With inductive transmission of the measured value using a non-contact connection, Memosens

guarantees maximum process safety and offers the following benefits:

• All problems caused by moisture are eliminated:

– Plug-in connection free from corrosion

– Measured values cannot be distorted by moisture.

– Can even be connected under water

• The transmitter is galvanically decoupled from the medium. Issues concerning "symmetrical high-

impedance" or "asymmetry" or an impedance converter are a thing of the past.

• EMC safety is guaranteed by screening measures for the digital transmission of measured values.

• Intrinsically safe electronics mean operation in hazardous areas is not a problem.
