Hi tpetar,
one more clarification from u.. watever the sensor is, we should be able to measure quiescent voltage, but i am not able to measure tat... :???:
u can check this **broken link removed**
unfortunately the sensor i am using has been stopped.. is my sensor is failure? and i have...
so i can use the sensor i am having now without the load...?
actually i am measuring same voltage reading across the load and directly from sensor output...
thanq for the reply..
i need voltage output with proportional to the magnetic field..
the current must be passed through the hall element in the sensor, then only we get the voltage.. What do u mean by circuit current should not pass??
else shall i use capacitor across voltage regulator input...
i am using hall sensor and i have connected as shown in the attached picture.. As in the datasheet mentioned, the quiscent voltage of about 2.5V is not coming.. Instead i am measuring I am measuring 0.71V without magnet and 0.11V when magnet placed near to it...Please let me know what mistake...
Hi!!
I am using this hall sensor **broken link removed**
i got 2 problems:
1. When i vary the magnetic field, the hall sensor is acting like digital, i mean, it showing either high value or low value... Its not varying linearly as the distance between the magnet and sensor varies.
2. The...
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..
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...
HI all!!
I tried with new hall sensor of the same type and made connections.. but still it showing 0.7V when there is no magnetic field.. why i am not getting 2.5V??:???:
Hi,
I'm ready to move from plastic breadboard to the soldering type of prototype PCB. What i immediately notice is that I'm missing the very useful "connected strips" - those long strips that run at the bottom of the plastic breadboard that allow you to easily connect all your +5V and grounds...
Hi all!!
I am using data acquisition, in which it has D25 as output and D15 port as input.. the D25 is connected to the PC thru the cabel.. I am using 3 pin hall sensor, the output of it should be connected to the pin8 of the D15.
Now my question, is tat possible to connect directly to the...
Ok now i will tell u wat i have done... Without using any proto circuit board, i directly soldered the wires to the pins... i have taken the wires from the 9V battery and soldered to the 5V voltage regulator and then soldered to the hall sensor... is this might be the error???
