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.

2. 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.
Screw for brightness

Technical Manual 9601
REF: 382 7
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.

2.14 Safety considerations
•Do not touch wires while the processor is ON.
•A non-isolated power supply can be used provided that the 0V is connected to the frame.
•In the event of mounting on a metal panel, standard safety considerations require that the
power supply should be earthed to avoid electrocution.
•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
specifications, connect the device to a filtered and stabili ed power supply.
•Double-check all wiring before turning on the power supply.
•Do not use tin on the stripped wire that might cause the strand to break.
•Install at maximum distance from high-voltage cables and power equipment.
•To avoid damaging the wire, do not exceed a maximum torque of 0.5 Nm (0.05 kgf.m).
•We recommend using crimp terminals for wiring. Use 26-14 AWG wire for all wiring
purposes.
•To maximi e the system performances, avoid electromagnetic interferences by mounting
the processor on a metal panel and earthing the power supply.
Note: The wire used to earth the power supply must not exceed 8 cm in length. If your
conditions do not permit this, do not earth the power supply (cf. step 2 § 3).
2.15 Relay outputs
15 relay outputs are available.
In our configuration, 9 relay outputs are used as follows:
Physical value Relays
Viscosity 1 NO relay for LOW threshold
1 NO relay for HIGH threshold
Compensated Viscosity
1 NO relay for LOW threshold
1 NO relay for HIGH threshold
Temperature 1 NO relay for LOW threshold
1 NO relay for HIGH threshold
Density 1 NO relay for LOW threshold
1 NO relay for HIGH threshold
Diagnosis - Dysfunction 1 NO relay
- Normal functioning: The coils of the relay are under tension and the contact is closed.
- In case of anomaly: The coils are not under tension and the contact is opened: measurements
out of set point, processor power supply is turned off…
- Power cut-out:
Relays O2 to O7 and relays O8 to O15: 3 A maximum per relay, 250VAC or 30VDC
Common: 8 A maximum
Common is not located, refer to the plugging chart
Minimal charge: 1mA for 5VDC
Relays lifespan: 100 000 operations at the maximum charge
Response time: 10 ms
If these relays are used to commute some inductive charge, we advise you to add some RC
networks to the charge terminals (preferably) or to the contacts terminals. They will then lessen
the electro-magnetic phenomena.

2.19 Wastes handling
Within the framework of the directive 2002/96-CE application, commonly named directive
DEEE, relating to the wastes of electric and electronic equipment, SOFRASER considers taking in
charge the equipment arriving at the end of the lifetime.
Do not throw the equipment to the dustbin. If the user does not have the means to take in
charge the wastes of our electronic equipment, he should returned these equipment to our factory
with a signed letter confirming that it is an equipment that has to be destroyed/recycled.

3. Processor mounting-installation
Warning:
The mounting panel should not be more than 5 mm thick.
Step 1
Make a panel cut-out as following:
Step 2
Earth the power supply
- Bore a hole of Ø4 mm that suits the NC6-32 screw
supplied.
- Scrape the panel paint away from the contact area to
ensure a conductive connection.
- Drive the screw into the hole and place the following
hardware in this order: washer, ring cable shoe, second
washer, spring and nut.
Note: The wire used to earth the power supply must not
exceed 8 cm in length. If your conditions do not permit this,
do not earth the power supply.
Step 3 Slide the processor into the cut-out, ensuring that the rubber seal is in place.

Technical Manual 9601
REF: 382 15
Step 4
Push the 4 mounting brackets into their slots on the processor sides as shown as
following:
Step 5

4. Communication
4.1 Serial interface
2 RS ports are available. One is a RS232 (PORT 1), the other one can be either a RS232 or a
RS485 (PORT 2). They are located on one side of the processor.
Serial ports type: RJ-11.
Caution:
- Turn off power before making communication connections.
- Do not connect the controller directly to a telephone or a telephone line.
- Use shielded, twisted pair cables.
- Minimi e the length of the connection cables. The length should not exceed 1200 m.
- Do not cross A and B signals: the positive terminals must be wired to +, and the negative
terminals to -.
- The RS232 port is not isolated.
- The RS485 serial port is not isolated. If the controller is used with a non-isolated external
device, avoid potential voltage that exceeds ± 10V.To avoid damaging the system, all non-isolated
device ports should relate to the same ground signal.
- Signals are linked to the processor’s ground, this is the same ground used by the power
supply.
