5. DESCRIPTION
Type 8201
Description
5.1. Area of application
The electrolyte monitoring is intended to control the level of electrolyte
in the electrolyte bottle of the pH sensor type 8201.
5.2. General description
5.2.1. Design
The electrolyte monitoring comprises (see Fig. 1):
• A sensor that contains two ultrasonic cells: an emitter and a
receiver;
• A screw-on cover that maintains the flexible hose in the sensor;
• A 5-m cable fitted with a right-angle M12 plug, that contains one
yellow and one green LEDs.
The electrolyte monitoring requires a power supply of 12-30 VDC and
has a PNP output which can be connected to an alarm. The electrolyte
monitoring is equipped with an M12 5-pin male fixed connector.

5.2.2. Measuring principle
The sensor contains two ultrasonic cells: an emitter and a receiver.
The ultrasonic emitter transmits short high-frequency pulses. The
ultrasonic receiver analyzes the signal received:
• If the hose is filled with liquid, a part of the ultrasound is transferred by the emitter through the hose to the receiver. The yellow
LED is ON and the output is active.
• If the hose is empty or if there is a bubble, the part of the ultrasound received by the receiver is much lower. In that case, the
yellow LED of the connector goes out to indicate an error and the

7. INSTALLATION AND WIRING
7.1. Safety instructions
DANGER
Risk of injury due to electrical voltage
• Before starting work, make sure that you switch off the supply
voltage and secure it to prevent restarting.
• Observe all applicable accident protection and safety guidelines
for electrical equipment.
WARNING
Risk of injury due to non-conforming installation.
• The electrical and fluid installation can only be carried out by
qualified and skilled staff with the appropriate tools.
• Respect the assembly instructions.
Risk of injury due to unintentional switch on of power supply
or uncontrolled restarting of the installation.
• Take appropriate measures to avoid unintentional activation of
the installation.
• Guarantee a set or controlled restarting of the process subsequent to the assembly of the device.
7.2. Installation on the electrolyte hose
DANGER
Risk of injury due to the nature of the fluid.
• Respect the regulations on accident prevention and safety relating to the use of aggressive fluids.
NOTE
The electrolyte monitoring may be irremediably damaged if
liquid is spraid between the ultrasonic cells.
• Always install a dry hose in the electrolyte monitoring.
The electrolyte monitoring is installed on the electrolyte hose which
joins the electrolyte vessel to the pH sensor type 8201.
→ Clamp the sensor on the electrolyte hose as close as possible to
the output of the electrolyte vessel (see Fig. 4).
