INSTALLATIONPRODUCT DESCRIPTION
• Full online wireless option via Bluetooth 5 for easy
monitoring, configuration and calibration
• Encrypted data exchange with mobiles (Android & iOS)
4.2 Hardware Description
The VisiTrace mA sensor consists of a sensor head with inte-
grated electronic and a sensor shaft in contact with the measured
medium. The sensor shaft is terminated by the optical dissolved
oxygen (ODO) cap, carrying the oxygen sensitive luminophore.
During development, special attention was paid to an optimum
sanitary design.

4.3 Optical DO measurement
The optical measurement principle is based on the so-called
luminescence quenching. The luminescence of certain organic
pigments (luminophore) is quenched in the presence of oxygen.
The luminophore absorbs the excitation light and release a part of
the absorbed energy by emission of fluorescence. In the presence
of oxygen, energy transfer takes place from the excited lumino-
phore to oxygen. The luminophore does not emit fluorecence and
the measurable fluorescence signal decreases.

4.4 VisiTrace mA with Micro-Transmitter
inside
With the micro-transmitter integrated, VisiTrace mA sensors offer
fully compensated signal directly to the process control system.
Communication protocols include standard analog 4–20 mA or
digital HART. The micro-transmitter located in the sensor head
stores all relevant sensor data, including calibration and diag-
nostic information, simplifying calibration and maintenance.
5 Installation
5.1 Unpacking
1) Unpack carefully the VisiTrace mA sensor. Enclosed you
will find the VisiTrace mA sensor, the Declaration of
Quality, the VisiTrace mA Operating Instructions, and the
Stainless Steel Inspection Certificate.
2) Inspect the sensor for shipping damages or missing parts.
