2015年3月5日 · The output swing of the INA125P is approximately 4V (4V - .5V is approximately 4V). The multiplier ("gain") required to bring .004V to 4V is 1000. An ideal InAmp or OpAmp would be able to output voltages from GND to Vin (whatever voltage you're powering them with).

2013年10月7日 · My classmates and I are creating a device which needs to dump a tray of sand after it has reached a specific mass. We attempted to follow this tutorial: We are using a load cell salvaged from a pocket scale capable of measuring to one tenth of a gram. This is our circuit at the moment: And here is the code: // Arduino as load cell amplifier // by Christian Liljedahl // christian.liljedahl.dk ...

2014年10月2日 · I am using an INA125P to amplify the signal to my Arduino as per the diagram below: I have a regulated 9v dc external supply powering the entire system. I am using a booster to increase the voltage to 10V to the load cells as that is the specified excitation voltage. I am also using this 10V supply to the INA125P

2015年7月27日 · INA125P is connected to 5v. 32u4's VREF is 5volt due to other sensors , so I wish a 0...~5v output. Schematic is attached. Regardless of gain, the max output is only 0 to 0,24v Vref , measured at INA125 pin 4/15 is 3,7v The load cell is a 1mV/V type, pretty common. Why is the output voltage so low ? - Is there a faster way to adapt it to output 0..5v for the 10bit ADC or 32u4 - or should I ...

2014年12月20日 · Hi, I am trying to interface Load cell with arduino UNO(328P) and using INA125P as instrumentation amplifier i have 5 wire load cell RED = E+ Black = E- Green = S+ WHITE = S- Shield wire i am using this as a reference for connection and code. the values i am getting as a result vary too much that there is too much difference in values with NO LOAD applied. i havn't use the shield wire do i ...

2012年10月9日 · So I purchased a 2kg scale with the intention to link it to an arduino to send the scale readings to the serial port for further use. I obtained a INA125P In-amp with the hopes to amplify the signal to do this. There are several examples out there of folks hacking scales in this manner. I am running into some issues where the output sweep seems to be limited and I'm not sure why. The ...

2018年11月12日 · im using a INA125P to amplify a load cell. the load cell output goes to a 16 bit ADC (measurin differential voltage) that communicates with an UNO. the Uno, adc, and amplifier share a common ground. its a 2000lb load cell with a 3 mv/v slope. Granted its oversize for what i need but it still should work. i am using a single sided power supply (can make it a dual with resistors if needed ...

2024年8月25日 · Buonasera a tutti, sto usando l'amplificatore per strumentazione INA125P per leggere su uno degli ingressi analogici del MEGA 2560 R3 l'output di una cella di carico. Per inciso, uso una delle tensioni di riferimento dell'integrato per alimentare il ponte (ponte intero). Sto alimentanto l'INA125P con tensione duale +12V, -12V. Ho realizzato anche un piccolo circuitino di supporto (come ...

2013年11月9日 · The INA125P is an amplifier, capable of amplifying a signal up to 10,000x. It will work with a load cell but without an accompanying analog-to-digital converter (ADC) you'll be stuck with the Arduino's 10bits of precision (1024 measurement points). The MCP3551 is an ADC converter with 22bits of precision (4,194,304 measurement points).

2015年4月6日 · Hello, I am trying to measure milli gram loads using a 100g load cell from Phidgets: Single Point Load Cell- 100g - 3139_0 at Phidgets I could not find a load cell which measures deci grams or smaller loads. There are such load cells from ATI but they cost thousands of dollars ☹ If anyone can suggest me a cheaper source, that would be really helpful. From other forum topics it seems like ...
