You have to take many instantaneous measurements of both voltage and current and average them over time to get true power. This larger scale factor, when properly designed for, can offer better measurement resolution. As always any help would be appreciated.
ACS754 Current Sensors
Assuming a more or less pure sinewave, current follows the same pattern, However, for anything other than a pure resistive load, voltage and current will be out of phase and you may or may not have a sinewave. He also told me the data sheet for the ACS has some peek voltage circuit examples which I am going to look at right now. It will also change with non-linear loads which most electronic gear presents. The device should not be purchased for new design applications.
Your PAUSE means you are only sampling a few times per second and so are unlikely to get the peak. Again if anyones worked with one of these current sensor and has any good code examples they found worked I would not mind taking a peek at that. Key in the picture below is the reminder to make solid connections. Sign up using Facebook. The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near the die.
Successfully using this sensor requires applying the correct scale factor and offset. I came up with this routine that seems to be pretty stable. The table below is derived from the ACS Datasheet. You had me at thus Home Questions Tags Users Unanswered. Print Share on Tumblr.
Madmanguruman, thank you very much, I don’t knew what was that sensor According to the manufacturer’s website, this is a discontinued part: Request Current Sensor Samples. The current is rising and falling with the AC so I am not getting a steady reading.
Either refer to the comments in the code or in the table above. Email Required, but never shown. The only way to do this accurately is with many nearly simultaneous samples of current and averaging over time. This allows the ACS75x family of sensors to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques.
The heavy gauge leadframe is made of oxygen-free copper. What I am having a problem with is as I said the same as the other person. These parts are no longer in production. The ACS is offered in four ranges.
Allegro MicroSystems – datasheet pdf
The scs754 of the conductive path are electrically isolated from the sensor leads pins 1 through 3. The example code here should be modified to match your particular sensor.
Trial and error and possible solution I’ve been trying allot of different approaches to my dataxheet not wanting to give up and certainly not going to wait for someone to drop code in my lap. You could improve on this by using an op-amp to amplify the difference in voltage, and then output a single DC voltage corresponding to the current.
Results 1 to 9 of 9. The uni-directional sensors measure current in one direction only and thus allow for a larger scale factor. This sensor is for A. The time now is Members who datashee read this thread: When I turn it on the current follows the AC and my reading goes from This is equal to 2.
He also told me that the have an 8 pin version that for my application will read up to 30 amps and I should really be looking at that. By continuing to visit this site you agree to accept cookies. ADC input using a current transformer?
