1.3 Technical data

Function

Sensors of the InPro®8000 Series are optical sensors which measure the concentration of suspended particles in a liquid medium on the basis of the principle of backscattered light. The Transmitter Trb8300 is equipped with a LED which beams a light – almost in the infra-red range (wavelength 880 nm) – via a fiber optic cable into the liquid medium. If the light hits on particles, then it is scattered in all directions. The light scattered at an angle of

InPro®8000 Series 7

180° (backscattered light) is captured and led back via a fiber optic cable to a photodiode in the transmitter, processed as photocurrent and the signal transformed into a value for the transmitter display.

The sensors are divided into two types, single and dual optical fiber sensors. The difference relates to the number of optical fibers present at the end (nose) of the sensor shaft.

At low particle concentrations, the measuring range is expressed in FTU (Formazin Turbidity Units). At high concentrations, the measurements are given in grams of suspended solids per liter of sample volume, using diatomaceous earth as reference substance.

– The metal body of the turbidity sensors as well as the safety weld-in

sockets METTLER TOLEDO housing InFit Typ 76*-*** and InTrac 7**-*** are, if necessary, to be included into the recurring pressure test of the unit.

– The turbidity sensors may only be operated in conjunction with the

transmitter Trb 8300.

3. Initial start-up

3.1 Handling

The fiber optic cables have a core of Hard Clad Silica (HCS) fibers. When laying fiber optic cables, the bend radius must always exceed at least 10 cm (4"). Fiberoptic cables may never be shortened independently. Fitting of the SMA plug requires special tooling. The transparent plastic cap on the sensor is to be removed before use. Any formation of deposits of solid particles on the surface is to be avoided. Gas bubbles in the process medium are also able to produce a signal and are therefore to be avoided wherever possible. If this is not viable, please refer to the instruction manual of the METTLER TOLEDO Transmitters Trb8300 (chapter:

«Calibration»).

3.2 Installation in vessels/reactors

The turbidity sensors are to be installed at a distance of at least 10 cm (4") from the walls of the vessel, agitator and other internals, in order to prevent disturbances through reflections. When employing special METTLER TOLEDO retractable housings InTrac with modified immersion tubes, the installation guideline valid for each individual housing is to be observed. This step likewise, is to avoid measurement disturbances arising from irrelevant light reflections (see chapter 7.2: «Accessories/Housings»).

InPro®8000 Series 13

3.3 Installation in pipes

The turbidity sensors are to be installed such that the distance from the pipe walls is at least 10 cm (4"). If this is not feasible in pipes of small diameter, then the sensor can be installed sloped, at an angle of 15…45° or, alternatively, in a knee bend. The pipe must always be completely full of liquid.

3.4 Calibration in open laboratory vessels

If the turbidity measuring system is calibrated off-line, it is recommended to use the METTLER TOLEDO calibration tool, «CaliCap» (order no. 52 800

210), for fitting on the sensor shaft. If «CaliCap» is not used, a minimum distance of 10 cm (4") to the vessel walls has to be observed as well. During calibration, the sample should be stirred in order to prevent the sedimentation of solid particles.

3.5 Fiber optic cable extensions

Fiber optic cables are available according to the list in chapter 7.2 «Accessories». The duplex cable extensions are supplied complete with

four fitted SMA plugs and two couplings. The two SMA plugs of the sensor fixed cable are to be screwed hand-tight onto the couplings. Two SMA plugs of the extension cable can then also be screwed by hand onto the couplings in any order. To protect the cable connection from dust and splashwater, it is recommended to use the METTLER TOLEDO Connection Box IP65 (Nema 4X) (order no. 52 800 241).

If extension cables are installed subsequently at a later date, the measuring system has to be newly calibrated (see instruction manual for the METTLER TOLEDO Transmitters Trb8300, chapter: «Calibration»).
