IMPORTANT

THE OFFSET ADJUSTMENT IN THE AIR MUST

BE THE FIRST TASK COMPLETED.

clean and dry the ibrating rod of the iscometer in order to make it

neat and dry;

be sure the process is empty. The rod must be ibrating in the air;

install the sensor on the process and fix it with its 4 screws;

power on the de ice and wait 15 minutes;

The MIVI+9000 is a complete digital system that can only communicate with other

de ices 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 accessory de ice, the zero adjustment in the air should be done on the

9510/9710 de ice (see 9510/9710 technical manual deli ered with the unit).

1Transducer 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 another cable

type or length because they are all a part of the resonant loop so they are matched together as one

ibrating system. The MIVI+9000 is specially designed to be used with Sofraser HMI/PLC accessories

(see chapter 3).

The acti e part of the sensor is composed of a ibrating rod held in oscillation at resonance fre-

quency by dri ing magnets. When the rod is immersed into a iscous material, the amplitude of the

ibration is dampened. The ibration amplitude aries according to the product iscosity where the

rod is immersed.

The sensor recei ing coil detects the response and the signal is con erted to a iscosity alue

through the electronic de ice. The factory calibration is performed with standard oils.

The transducer acquires the coils’ amplitudes and frequency and generates arious signals.

These signals represent the properties being measured. It is also in charge of powering the whole

system. It gi es iscosity and temperature information through the serial communication.

2Transducer technical characteristics

2.1 DIN-rail Mounted enclosure

2.1.1 Mechanical characteristics

Hereunder are the different iews 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 a oid any damage on the elec-

tronic board.

The operating temperature for this electronic de ice should be constant, the maximum is 50°C.

The electronic de ice deli ers the iscosity 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 de ice’s 0V pin.

9000 Technical Manual

REF.: 381/2 6

In the e ent of oltage fluctuations or non-conformity to oltage power supply specifications,

connect the de ice to a filtered and stabilized power supply.

Double-check all wiring before turning on the power supply.

Install at maximum distance from high- oltage cables and power equipment.

To maximize the system performances, a oid electromagnetic interferences by mounting the

processor on a metal panel and earthing the power supply.

2.1.3 System connexion

Only the link between the sensor and the terminal block has to be operated by the user accord-

ing to the following description.

2.2 IP67 Enclosure

2.2.1 Mechanical characteristics

Hereunder are the different iews 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 a oid any damage on the elec-

tronic board.

The transducer box is IP67 and can be mounted on a panel or a plate through 4 screws.

The operating temperature for this electronic de ice should be constant, the maximum is 50°C.

This enclosure is equipped with 3 cable glands.

The electronic de ice deli ers the iscosity and temperature information to the selected HMI

through the serial RS-485 communication port.

3Accessory devices

The 9510 and 9710 de ices ha e been designed as accessories to the MIVI+9000 sensor.

3.1 9510

The 9510 is an accessory controller that is to be connected to the 9000 transducer of the MIVI

sensor in order to add numerous functions to the whole system.

The 9510 electronic de ice has been designed in order to control 1 MIVI sensor. This means the

MIVI’s transducer 9000 and the 9510 are connected in a RS-485 serial loop as shown in the

scheme just abo e.
