IMPORTANT
THE OFFSET ADJUSTMENT IN THE AIR
MUST BE THE FIRST TASK COMPLETED.
1. CLEAN AND DRY THE SENSOR ROD.
2. BE SURE THE PROCESS IS EMPTY. THE ROD MUST BE VIBRATING IN THE AIR.
3. INSTALL THE SENSOR ON THE PROCESS AND FIX IT WITH ITS 4 SCREWS.
4. POWER ON THE DEVICE, WAIT 15 MINUTES.
The MIVI+9000 is a complete digital system that can only communicate with other devices
through its serial RS-485 port. Hence, to make the zero adjustment in the air, only a digital
transmission through this port can be applied, it must be installed with its 9510 or 9710 ac-
cessory device, the zero adjustment in the air should be done on the 9510/9710 device (see
9510/9710 technical manual delivered with the unit).

1. Transducer principle
The measuring chain is composed of three inseparable elements: the sensor, its cable and the
9000 transducer that controls it. The sensor cannot be used with another transducer or an-
other cable type or length because they are all a part of the resonant loop so they are
matched together as one vibrating system. The MIVI+9000 is specially designed to be used
with Sofraser HMI/PLC accessories (see chapter 3).
The active part of the sensor is composed of a vibrating rod held in oscillation at resonance fre-
quency by driving magnets. When the rod is immersed into a viscous material, the ampli-
tude of the vibration is dampened. The vibration amplitude varies according to the product
viscosity where the rod is immersed.
The sensor receiving coil detects the response and the signal is converted to a viscosity value
through the electronic device. The factory calibration is performed with standard oils.
The transducer acquires the coils’ amplitudes and frequency and generates various signals. These
signals represent the properties being measured. It is also in charge of powering the whole
system. It gives viscosity and temperature information through the serial communication.

2. Transducer technical characteristics
2.1 DIN-rail mounting IP20 enclosure
2.1.1 Mechanical characteristics
Hereunder are the different views of the electronics.
The processor must be connected to a stabilized and filtered 24 VDC (± 2.4 VDC) power supply. The
polarity of the power supply is highly important, in order to avoid any damage on the elec-
tronic board.
The operating temperature for this electronic device should be constant, the maximum is 50°C.
The electronic device delivers the viscosity and temperature information to the selected HMI
through the serial RS-485 communication port.
2.1.2 Safety considerations
Do not touch wires while the processor is ON.
Do not connect either the “Neutral” or “Line” signal of the 110/220VAC to the device’s 0V
pin.
In the event of voltage fluctuations or non-conformity to voltage power supply specifica-
tions, connect the device to a filtered and stabilized power supply.
Double-check all wiring before turning on the power supply.
Install at maximum distance from high-voltage cables and power equipment.

REF: 381/3 6
To maximize the system performances, avoid electromagnetic interferences by mounting
the processor on a metal panel and earthing the power supply.
2.1.3 System connection
Only the link between the sensor and the terminal block has to be operated by the user according
to the following description.

2.2 IP66 Enclosure
2.2.1 Mechanical characteristics
Hereunder are the different views of the IP66 enclosure.
The processor must be connected to a stabilized and filtered 24 VDC (± 2.4 VDC), 1 A power supply.
The polarity of the power supply is highly important, in order to avoid any damage on the
electronic board.
The transducer box is IP66 can be mounted on a panel or a plate through 4 screws.
The operating temperature for this electronic device should be constant, the maximum is 50°C.
This enclosure is equipped with 3 cable glands.
The electronic device delivers the viscosity and temperature information to the selected HMI
through the serial RS-485 communication port.
2.2.2 Safety considerations
Do not touch wires while the processor is ON.
Do not connect either the “Neutral” or “Line” signal of the 110/220VAC to the device’s 0V
pin.
In the event of voltage fluctuations or non-conformity to voltage power supply specifica-
tions, connect the device to a filtered and stabilized power supply.

2.2.3 System connection
All the connections to the electronic device are made on the terminal block located inside the blue
enclosure.
All the wiring between the electronic board and the terminal block are not to be touched.

pin.
In the event of voltage fluctuations or non-conformity to voltage power supply specifica-
tions, connect the device to a filtered and stabilized power supply.
