Catalog and Information About IFX/C04/P

01/28/2014 6:06 AM

Does anyone has a catalog and information about IFX/C04/P optical oil streak sensor?
Thanks in advance.
Shyam

Look at "schmieranlagen srl" it is an Italian company selling own products and those from a specialist in lubrication (minimal) from Germany.

It works by measuring the "shadow" intensity of the air-oil flow in an infrared ray. The presence of minute oil drops carried by the air flow leads to a loss of intensity on the receiving diode. It depnds on the drop dimensions and density. Needs a calibration.

Several years ago I was involved in a pre-study for a car manufacturer who was interested to control and as well decrease the oil quantity in the compressed air used for assembly tools on the assembly line. They were interested but had no money to finance the design. Typical automotive industry they want you to supply and to pay for the honor of being their supplier.

Have you seen these sensors? I wonder why catalog is not online.

No but I know how this type of sensor works. I presume that they sell it as part of a more important delivery.

Why do not ask for an offer with detailed technical documentation ?

I did get information from Italian Company.

They say it is an image sensor for air + oil streak (patent filed - not known where) and is programmed for threshold level detection. I am yet to get more details on how they do it. I have also asked them to send me a quote for 5 sensors and some programmer for threshold value to let me test the sensor first. I think they ship pre-programmed and perhaps with calibrated threshold value set by them. As I want to experiment with the sensors, I need to change the values.

I have got some lubricant oil and going to have a setup to generate air + oil mixture and for various desired concentration levels of lubricants, and I am going to experiment with. If there was analog output from sensor then it might have helped much better but they don't have such output.

There may be some other manufacturers also having such device with different method of detection. This sensor is very compact so looks good but no idea about its performance as there is no data anywhere.

The basic principle is VERY simple it consists in an infrared source -LED- and a light sensor which can be either a Se or an array. The array has the advantage to "see" as well the particles sizes.

The problem is the size of the particles they have to be so small that no coalescence could occur.

As these sensors are streak sensors, the trace will be seen as large line rather than a point. In fact if there is no change in the image pixel parameters then it simply means no flow at all even though there may be a drop stuck in the sensing tube which can be sensed by ordinary sensor. It is a dynamic sensor. Tube size is 4 mm. Flow rate will make the trace length per unit time of sampling in the CCD array. Perhaps 4-line arrays of 1024 pixels or even smaller numbers may just be good enough.

I used to buy such sensors from TAOS which was Texas Instruments company and perhaps it is now sold out.

Normally for Organic fluids excitation wavelength is shorter than 350nm as fluorescence is in 400nm band. You never use IR in these sensors. Sensing is done at 90 degree in fluorescence emission sensing. Light comes out from droplets and there may be some phosphorescence time delay also.

Can somebody tell how much is this sensor?

Thanks in advance.

Yes. The vendor can. Make some calls, perhaps?
