Important information for using this adapter together with a SensoLyt armature:
Observe the following note when you want to use a SensoLyt measuring armature with the aid of the adapter:
Warning For safety reasons, use only electrodes especially specified for high pressure and temperature loads (for example pH combination electrode SensoLyt SEA-HP, order no. 109 118). For more information, refer to the YSI catalog or the Internet. YSI assumes no liability for damages caused by using different electrodes.

General installation recommendations
Basic types of
installation
The optimum installation location must be individually deter­mined for the type of sensor and the application.
Influential factors
The table on the following pages contains recommendations and the special characteristics of the individual sensors.

Burdening of the measuring medium with
long fibers - avoidance of them getting caught on the sensor (rake effect)

Burdening of the sample with small stones
and abrasive particles - avoidance of any damage to the sensor element

Avoidance of malfunctions of the optical
measurement (turbidity/total suspended sol­ids) by captured air bubbles and particles

B + Good flow
+ Low susceptibility to contamina-
tion
+ Low risk of membrane damage
TetraCon 700 IQ B + Good flow

tion
Check and adjust cell constants after installation (see sensor op­erating manual)
SensoLyt 700 IQ C + Good flow
+ Low susceptibility to contamina-
tion
- Danger of small stones damaging the electrode
The enclosed fixing ring instead of the protective hood improves the incident flow. Attention
: It is no protection
against small stones!
The best incident flow is achieved when the diaphragm points against the flow direction.
TFK 700 IQ C + Good flow
+ Low susceptibility to contamina-
tion
The enclosed fixing ring instead of the protective hood improves the incident flow.

Note
: Please note the special installation recommendations in the following section.
A + Optimum flow of the sapphire disc
so there is no capture of air bub­bles or large particles in front of the sensor
- Susceptible to fibers getting caught
- Risk of damage from stones and abrasive particles
Optimum installation location for measuring media without contamination from fibers, stones, or abrasive particles.
C + No risk of contamination by long fi-
bers
+ Low risk of damage from stones
and abrasive particles
- Susceptible to the capture of air bubbles or large particles in front of the sapphire disc (turbulence effect)
In the case of contamination by fibers, less prone to contamina­tion than A.
B + Good flow of the sapphire disc, so
there is no interference from air bubbles or large particles in front of the sensor
- Risk of light reflections in narrow containers
Good possibility in sufficiently large containers or high values of turbidity/total suspended sol­ids.

Special installation recommendations: VisoTurb 700 IQ and ViSolid 700 IQ
Note
Please also observe the general basic information in the I
NSTALLATION chapter of the sensor operating manual. There
you will find important notes on optimizing the installation.
45 ° pipe installation
Pipe diameter at the installation location of at least DN 80.
The pipe should be straight and not tapered for a length of at least 50 cm (VisoTurb 700 IQ) or 25 cm (ViSolid 700 IQ) in the direction of observation. Angled or tapered pipes can cause interference effects in the case of low turbidity.
The front part of the sensor is pitched towards the flow.
Exception: If there are high quantities of foreign bodies with fibrous or large surfaces, as for example hairs, strings or leaves, it may be of advantage to incline the sensor in the direction of the flow so that the sapphire disc does not face the flow.

The marking on the sensor shaft points towards the
pipeline. On page 9 you will find a description of how to correctly align the sensor with the aid of a marking aid on the sensor plug head connector.
90 ° pipe installation
Note
The 90 ° pipe installation is only suitable for large pipe diameters and high turbidity/total suspended solids values respectively. For other cases, the 45 °installation should be preferred.
For installation, select a location with a pipe diameter as
big as possible.
Rotate the sensor so that the marking on the shaft (arrow
symbol) points in the direction of the pipe axis. On page 9 you will find a description of how to correctly align the sensor with the aid of a marking aid on the sensor plug head connector.

3 Insert the sensor with the
retaining ring in the receiving tube (4) up to the stop.
4 Screw the sensor
adapter (5) on the unit. The sensor is ready to be installed in the retractable armature.
5 Install the sensor in the
retractable armature (see operating manual of the retractable armature).
6 Connect the SACIQ
sensor connection cable to the plug head connector of the sensor.
7 If necessary, rotate the
sensor by means of the marking aid until it is in the correct position.
* The receiving tube for installation with the ADA-WA 1 is included in the scope of delivery of the retractable armature. For installation with the ADA-WA 4, use the special (longer) receiving tube provided with the adapter in order to ensure the correct length compensation.
