Operating instructions
In a 3-A compliant installation, the neck height shouldn't be bigger than the neck diameter. Tank,
pipe and process connection (tank side) should follow the guidelines and applicable standards for
hygienic design such as roughness of wet parts Ra ≤ 0.8 µm.
Installation in a metal immersion tube or metal bypass
Diagram 2
Centering: To prevent contact between the probe and the bypass tube during oscillations, the probe
should be centered according to its length and depending on the diameter of the bypass tube. To do
this, it is necessary to insert one or two centering pieces (see Chapter 10 "Accessories").
Tank welds can affect the measurement accuracy.

1.5 Electrical connection

The sensor is connected using a pre-assembled cable socket with 1 x M12 plug connector (5-pin).
With the power switched off, plug the cable socket into the sensor and screw it tight. Connect the
cable according to its function. After the supply voltage has been applied, the sensor carries out a
self-test. Once installed, the sensor is ready for operation on completion of the self-test (< 5 s). The
display shows the current measured value.
