REF: 382 5

1. Transmitter principle

The measuring chain is composed of three inseparable elements: the sensor, its cable and the 9601

processor that controls it. The sensor cannot be used with another transmitter or another cable

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

vibrating system.

The active part of the sensor is composed of a vibrating rod held in oscillation at resonance

frequency by driving magnets. When the rod is immersed into a viscous material, the amplitude 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 processor 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 analog outputs, serial communication and

displays it. The processor also allows settings as the very important “ ero in the air” procedure.

Processor technical characteristics

2.1

Electronic device size

The electronic box has the purpose to be ﬁtted in a panel, close to the process line. The collar

is the only visible part, composed of a face plate and a LCD screen. It is continuously

displaying the viscosity value and, in the case there is a Pt100 probe, the temperature value.

The ID label is stick on the back panel with main information (see §2.6).

2.2

Mechanical characteristics

•Dimensions behind the collar: 138 x 123 x 106.4 mm

•Collar dimensions: 184 x 155 x 6.7 mm

•Case transducer dimensions : 66.2 x 67.1 x 28.2 mm

•Cut-out for assembly on panel: 141 x 126 mm. Thickness ≤ 5mm.

•Weight: about 515 g.

•Tightness: IP 65 with panel mounting and IP20 on rear panel.

•Operational temperature: 0 °C to 45 °C.

2.3

Display

•Display type: STN LCD

•Illumination backlight: LED yellow

•Display resolution: 128 x 64 pixels

The brightness can be adjusted using the screw on the top panel

2.4

Keyboard

24 keys: alphanumeric keys and function keys.

2.5

Battery

The battery lifespan is about 7 years at 25 °C. When the battery no longer works, the

operating parameters of the sensor are no longer stored in memory. It is then necessary to foresee

the change of the battery after 5 years of use of the sensor.

2.6

Consumption

The processor requires a 24 VDC (± 2.4 V) stabili ed and filtered power supply (not provided

by SOFRASER).

Typical power consumption: 7.2 W maximum

2.7

Connection blocks

On the processor back module, various categories are identified (example: DIGITAL INPUTS,

ANALOG OUTPUTS…).

We will call these categories "connection blocks". The diagram below identiﬁes the various

connection blocks. The colours codes used and the name of these connection blocks are taken

again for each connection diagram.

If there is no incorporated Pt100 probe, there are no E, F and G wires to connect. In the case

of a non-provided by SOFRASER external probe, be sure this is a 3-wires one.

An external circuit protection device (such as a fuse) is recommended as shown in (2).

See §3 for power supply earthing (3).
