high pressure cabeling

[vamsee]

Hi all!! the picture shows the attachment of my magnet to the ball valve and placement of hall sensor...

I need to house or cable the hall sensor, such that it withstands 100 bar pressure and 200°C temp. the cabel should extend about 2meters, so that it reaches my Data Acquisition board.

And is there any high temperature adhesive to stick my magnet to the ball valve (other than sticking, new ideas also welcomed to share with me)..

If u need further details, pls ask..

thanq

Drill a hole and thread it and use something like this:

The magnet is another story. It would have to be somehow fused into the ball.

I assume the sensor is there to determine the position of the valve?

If this is the case then perhaps an optical sensor is easier to implement?

thank you for the reply.

I have selected the hall sensor because it has high operational temperature.. **broken link removed**

yes u r correct, it is to find the position of the ball valve.. I need to know how the wires should be cabeled so that it can withstand 200°C and 100 bars..

According to the datasheet this device can only work up to 150 deg C!!
And it is a PCB mounted device (SMD or TH) that requires a fairly large polarized decoupling capacitor. Without active cooling and mechanical protection it will never withstand 100bars and 200 deg C.

Check the link from my previous post. This is the device you should look for. It is sealed and protected by a metal enclosure. Still 200 deg C may be a problem.
