1 GETTING STARTED The Veloce System is a high-speed and universal fiber-optic signal conditioning instrument that can be used to perform relative Strain, Temperature, Force & Load, and Pressure measurements in hostile locations that were formerly inaccessible with other measuring instruments. The Veloce System is an expandable instrument that can accept up to eight Veloce plug-in modules. Each Veloce conditioner has a 200 kHz sampling speed. The following sections explain how to operate the Veloce System.

Veloce 50 2.3.3 Operating Manual ANALOG OUTPUT The analog output gives a voltage proportional to the value of the physical parameter measured by the fiber optic transducer. The analog output is a BNC-type coaxial connector. See section 6 for converting the voltage output value to the measured physical parameter value. 2.3.4 RESET BUTTON The Reset Button zeroes out the analog output of the Veloce Module. The «Reset» button has to be pressed each time a transducer is connected to the Transducer Input.
Veloce 50 Operating Manual 3 INSTALLATION 3.1 LINE POWER CONNECTION 1. Check to see that the line voltage is within the limits specified above; CAUTION: Operating the instrument on an incorrect line voltage may cause damage to the instrument, possibly voiding the warranty. 2. Before plugging in the power cord, make sure that the power switch is in the off (0) position; 3. Connect the female end of the supplied power cord to the AC receptacle on the rear panel.
Veloce 50 Operating Manual 3.2 COOLING AND INSTALLATION The Veloce SYSTEM is cooled by forced convection. Two exhaust fans located on the rear panel allow ambient air to flow outside the chassis of the instrument. The ambient air is drawn inside the casing from the ventilation louvers located on the bottom cover to the fans. CAUTION: The Veloce System chassis must be installed in area where ambient temperature does not exceed 40°C.
Veloce 50 Operating Manual 4 TAKING MEASUREMENTS 4.1 MATING THE TRANSDUCERS TO THE VELOCE CONDITIONER To use a transducer with the Veloce conditioner, simply mate the fiber optic transducer connector with the Veloce input connector. Once the transducer is connected, simply press the reset button and valid readings of the transducer will be present at the Analog Output connector. See section 6 for converting the voltage output value to the measured physical parameter value.
5 CONDITIONER–TRANSDUCER OPERATION This section contains important information for the proper operation of the Veloce conditioner. It is recommended to read this section before using the Veloce for the first time. 5.1 GAGE FACTOR Each of Fiso fiber optic transducer is delivered with a Gage Factor specified on the storage box and on the sensor itself, near the connector.
Veloce 50 Operating Manual 6 THEORY OF OPERATION 6.1 FABRY-PÉROT FIBER OPTIC STRAIN GAGES All of Fiso Technologies' strain gages are designed around a Fabry-Pérot interferometer (FPI). Basically, an FPI consists of two mirrors facing each other. The space separating the mirrors is called the cavity length. Light reflected from the FPI is wavelength-modulated in exact accordance with the cavity length.

Veloce 50 Operating Manual 6.3 RELATIVE VERSUS ABSOLUTE MEASUREMENTS All of Fiso' FTI, UMI, DMI and BUS series of fiber-optic conditioner are absolute measurement conditioners as opposed to relative measurement conditioners. However the Veloce series of conditioners offered by Fiso Technologies are relative measurement conditioner. The differences between these two types of conditioner are explained in the next paragraphs. 6.
Veloce 50 Operating Manual The relative strain value is expressed by the following equation: ε r (t ) = ε (t ) − ε (t 0 ) where: ε r (t ) is the relative strain as fonction of time ε (t ) is the absolute or true strain as fonction of time ε (t0 ) is the absolute or true strain at time t0 RELATIVE STRAIN MEASUREMENTS Absolute or true strain ε(t) ε(t 0) 0 Relative strain εr(t) Time Measurements started here Example 1 0 Relative strain t0 εr(t) Time Measurements started here Example 2 0 t0 Time
Veloce 50 Operating Manual 7 MAINTENANCE 7.1 REPLACING THE FUSE A rear panel fuse located next to the power receptacle protects the power line input of the instrument. If the line fuse needs to be replaced, performs the following steps: WARNING: Make sure the instrument is disconnected from the AC line and other equipment before replacing the line fuse. 1. Pull out the fuse holder located next to the power receptacle, at the rear of the instrument; 2.
Veloce 50 7.2.2 Operating Manual HOW TO CLEAN THE TRANSDUCERS AND CONDITIONER CONNECTORS Transducer connector STEP 1 FISO Technologies recommends cleaning the connector via the use of FISO Fiber Optic Connector Cleaner. To do so, ensure a new cleaning surface by advancing cloth tape. Tear off excess tape as required. STEP 2 Softly press connector and expose it to the cloth with motion illustrated in above figure. Up to 6 connectors may be cleaned before advancing tape.
Veloce 50 Operating Manual . 7.3 HOW TO PREVENT TRANSDUCERS DAMAGE AND ENSURE A LONG LIFE TO YOUR Here is a list of point forms that will help the user to prevent damages and ensure long life to his transducers. If you are working with a team or if it is the first time you are working with fiber-optic devices, it is a good idea to use this page as a reminder at your application location. Keep the fiber-optic connector surface clean.

Veloce 50 Operating Manual APPENDIX A COMMUNICATION VIA RS-232 PORT 8.1.1 CONVERSION FROM VOLTAGE TO DEGREES CELCIUS The temperature is obtained by multiplying the analog output span (APf), the voltage output (mV) and the calibration factor (CF). ΔT = CF * APf Variable CF * ΔV Example 1.012 oC/nm APf 0.01 nm/mV ΔV 3000 mV ΔT 30.36 oC Sources *Note1 Calibration Factor, written on each sensor box. *Note1 Analog Span f , stored in the conditioner memory.
Veloce 50 Operating Manual 8.1.2.2 Signal averaging Resolution improvement is achieved by averaging the input signal. The Veloce always make acquisition of the photo-detectors (input signals) at a rate of 200 kHz. The output rate is determined by the time constant. A time constant set at 0.001s corresponds to a refreshing rate of 1/0.001 s = 1 kHz. For the same time constant, the number of averaged samples is obtained by multiplying the time constant minus 0.000005 by 200 000Hz (e.g. (0.001s – 0.
8.1.3 8.1.3.1 REMOTE CONTROL Hardware settings The RS-232 serial connection to the Veloce is made through a DB-9 connector located on the front of the rack mount chassis. The Veloce is equipped with a RS-232 internal switch to give access to each module from one single RS-232 serial link. If your computer is equipped with a DB-9 serial port connector, then use a standard RS-232 extension cable (all wires straight through).
