Memosens COS81E

Function and system design
Measuring principle

Sensor structure
Oxygen-sensitive molecules (markers) are integrated into the optically active layer(luminescencelayer).
The luminescence layer, an optical insulating layer and a cover layer are applied on top of one
another on the carrier. The cover layer is in direct contact with the medium.
The sensor optics are directed at the rear of the carrier and therefore at the luminescence layer.
Measurement process (principle of luminescence quenching)
If the sensor is immersed in the medium, an equilibrium is very quickly established between theoxygen partial pressure in both the medium and the luminescence layer.
1.

The sensor optics send orange light pulses to the luminescence layer.

2.

The markers "respond" (luminesce) with darkred light pulses.
 The decay time and intensity of the response signals are directly dependent on the oxygen
contents and oxygen partial pressure.

If the medium is free from oxygen, the decay time is long and the signal is very intense.
Any oxygen molecules present mask the marker molecules. As a result, the decay time is shorter andthe signals are less intense.
Measurement result‣ The sensor calculates the measurement result on the basis of the signal intensity and decay timeusing the Stern-Volmer equation.

The sensor provides measured values for temperature and partial pressure as well as a raw measured
value. This value corresponds to the luminescence decay time and is approx. 14 μs in air andapprox. 56 μs in oxygen-free media.
For optimum measurement results
1.

During calibration, enter the current air pressure at the transmitter.

2.

If the measurement is not performed at Air 100% rh:
Enter the current humidity.

3.

In the case of media with high salinity:
Enter the salinity.

4.

For measurements in the units %Vol or %SAT:
Also enter the current operating pressure in the measuring mode.

Dependability
Reliability

Memosens technology digitizes the measured values in the sensor and transmits the data to thetransmitter via a . The result:• If the sensor fails or there is an interruption in the connection between the sensor and transmitter,
this is reliably detected and reported.
• The availability of the measuring point is reliably detected and reported.

Maintainability

Easy handlingSensors with Memosens technology have integrated electronics that store calibration data and otherinformation (e.g. total hours of operation or operating hours under extreme measuring conditions).
Once the sensor has been connected, the sensor data are transferred automatically to the transmitterand 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 theavailability of the measuring point.
• Thanks to the availability of the sensor data, maintenance intervals can be accurately defined andpredictive maintenance is possible.
• The sensor history can be documented with external data carriers and evaluation programs.
• Thus, the current application of the sensors can be made to depend on their previous history.

Integrity

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 remains free from corrosion• Measured value distortion from moisture is not possible.
• The plug-in system can even be connected under water.
• The transmitter is galvanically decoupled from the medium.
• EMC safety is guaranteed by screening measures for the digital transmission of measured values.

The sensor with the u-shaped spot cap must be installed at an angle of inclination of 0 to 180˚ in an
assembly, holder or a corresponding process connection. Recommended angle: 0 to 45° or 135 to
180 ° to prevent the attachment of air bubbles. At angles of inclination of 45 to 135°, air bubbles atthe oxygen-sensitive membrane may increase the measured value.
Inclination angles other than those mentioned are not permitted. In order to avoid buildup andcondensation on the spot, do not install the COS81E-*****U *** sensor upside down.
Follow the instructions for installing sensors in the Operating Instructions for the assemblyused.

Installation examples
Permanent installationassembly Unifit CPA842

The permanent installation assembly CPA842 enables easy adaptation of a sensor to nearly any
process connections from Ingold nozzles to Varivent or Tri-Clamp connections. This kind of
installation is very well suited for tanks and larger pipes. This enables a defined immersion depth of
the sensor into the medium in the simplest way.

Flow assembly CYA680

The flow assembly is available in various nominal diameters and materials. It can be installed both inhorizontal and vertical pipes. The assembly can be operated with 1 or 2 sensors.
