2.2 Device description
INFORMATION!
This manual details installation procedures and operational features of the KROHNE
OPTISENS 2000 pH and ORP sensors. Menu navigation and technical data for the MAC 080
converter can be found in the OPTISENS MAC 080 manual.
The PAS 2000 sensors are manufactured in SIS2343 (316SS) stainless steel and PVC. The
sensors are mounted onto the MAA 2000 Adjustable telescopic rod holder using a POM adapter.
An adjustable stainless steel slide rail holder is available as an option. All PAS 2000 sensors
incorporate automatic cleaning as standard. The electronics is protected in the rugged casing,
ensuring its reliability in very demanding environments.

2 DEVICE DESCRIPTION
The sensor has a fixed, shielded 10 m / 33 ft cable used for signal transmission between the
sensor and the MAC 080 converter. The cable sheath is made of Hytrel and is highly resistant to
aggressive materials and fluids.

3.3 Installing the sensor
3.3.1 Basic installation instructions
The electrode should be placed deep enough so that it always stays in the measuring media,
even when the level varies (see figure 3-1). The measuring ability of the electrode is influenced
negatively if the column of liquid to be measured is too large. For optimal results the column
should not exceed 300 mm / 12".
NOTE!
To protect the sensor from damage, the sensor should never be fully submerged into water.
Therefore a maximal immersion depth of 800 mm / 31" has to be maintained.
The sensor should be mounted in a vertical position. In some applications it may be desirable to
mount at a certain angle. In this case the angle from the horizontal plane should be greater than
or equal to 45°.
INSTALLATION 3
Figure 3-1: Installing the PAS 2000 in a flume
3.3.2 Mounting to MAA 2000 telescopic rod immersion holder
The mounting bracket of the telescopic rod is mounted to a handrail or a separate holder.
In case a handrail is not available, a mounting post with a vertical bar for sensor mounting can be
purchased from the manufacturer.
