2.2 Device description

2.2.1 Conductivity sensor

DEVICE DESCRIPTION 2

1 4-pin-right-angle plug 2 Process connection thread 3 Outside electrode 4 Inside electrode

The OPTISENS COND 1200 sensor is a conductive cellular measurement medium with an integrated temperature sensor (Pt1000). It contains two stainless steel electrodes with PVDF insulation that prevent proneness to soiling. It is available in various cell constants (c = 0.01,

0.05, 0.1, 0.2, 1.0) and thus covers a wide area of use. The conductivity sensor have a standardised robust design and a long lifespan. In combination with a signal converter, it is possible to create extremely reliable low-cost measurement systems, which is suitable for a wide range of water analysis measurement tasks. The conductive measurement principle is characterised by high sensitivity, especially at low conductivity values. For this reason, the sensor is perfect for low-contamined, non-corrosive media such as pure water, steam and cooling water as well as service water.

If the values exceed 20 mS/cm and in case of heavy soiling or danger of corrosion by the medium, it is highly recommended to make use of the inductive measurement with the IND 1000 (see handbook IND 1000).

• The original packaging serves the protection of the equipment. Therefore always use it for transport or return to the manufacturer.

• Avoid solar radiation.

INSTALLATION 3

3.3 Installation procedure

As a new inductivity sensor needs to be calibrated before it is installed into its final measuring location, it is important to follow the installation order:

1. Unpack the sensor.

2. Connect the sensor to the signal converter.

3. Calibrate the sensor.

4. Install the sensor into its final measuring location.

The required steps are explained in the following sections.

3.4 Pre-installation requirements

CAUTION!

Never touch or scratch the sensor shaft or the inner electrode.

INFORMATION!

•

Install the sensor against the flow to ensure direct exposure of the electrodes.

•

Install the sensor only in T-pieces or flow through assembly of the manufacturer.

•

Avoid air getting trapped around the sensor.

•

Avoid solids collection around the electrodes.
