The output goes no higher than 4. The app helped me a lot. If you have further questions related to this thread, you ina114 click “Ask a ina114 question” below.

My current INA setup consists of ina114 load cell in a Wheatstone bridge configuration that reads 0 mv with no weight on it. In reply to Ina114 Macias:.

INA114 voltage output range

Aug 6, 3: Do they change when you connect ina11 ina114 to the LM circuit? All content and materials on this site are ina114 “as is”. I’m using first an instrumentation amplifier, INA with a gain, to amplify load cell ina114 and it works fine.

So be sure to measure the differential voltage when the bridge is weighted and use an appropriate gain and Vref that will cause you to get the 5V or more that you specified in your post. Aug 5, 4: Ina114 you have any questions about the factors that ina114 limit your common mode voltage in instrumentation amplifiers, you can learn more about them from these series of articles: If you ina114 a related question, please click the ina114 Ask a related question ” button in the top right corner.

Hello My ina114 INA setup consists of a load cell in a Wheatstone bridge configuration that reads 0 mv with no weight on it. Sign up using Email and Password. When i test the V-F circuit with a variable DC supply ina114 works ina114 but ina114 connected ina114 INA’s, the output of V-F converter saturates ina114 to 5v and i don’t know why.

How is the load cell and INA ina114 I see a couple of design choices that may cause some problems with ina114 circuit: The below schematic is identical to the schematic I was using but instead of the voltage of 15V and V, it is 5v and ground to the microcontroller respectively. Do you have another question? When there is no weight on the load cell I ina114 the output to be 0v.

I bring ina114 up because the Vout of an instrumentation amplifier is given by the equation: What range of output voltages do you get out of your INA? Then load cell caracteristics are presented here: Did anybody have the ina114 problem; any help would be really useful.

Below is my new schematic layout ina114 I ina114 hoping inq114 correct this issue.

When weight is ina114 on it I want the output to go ina114 5v or higher. I removed the voltage divider and grounded the ref pin. Mentions Tags More Cancel. I breadboarded everything out and it seems to be working perfectly.

Adding a voltage divider and other resistors directly to this ina114 will change the impedance at that node and give you ina114 gain.

If you would like a tool ina114 can help calculate your common mode voltage range—which is covered in more detail by the linked series of articles—you can find it here: You can fix this by adding a buffer to the reference pin ina114 shown ina114 Figure 2 ina114 the datasheet: Iina114 fact, you encountered this exact problem before you when you had 5V and 0V on your supply voltages.

It is perfectly acceptable if the voltage goes above 5v or below 0v. First, I have posted the internal ina114 schematic ina114 the INA given in the datasheet.

With my current layout which is not pictured, I am using 5v from my microcontroller ina114 the ground from my microcontroller to power the INA Ask a new question Ask a ina114 question Cancel.
