Load Cell Adc Ic

Working principle of the circuit is very simple.

Load cell adc ic.

Figure 5 is a block diagram of a reference design a weigh scale system evaluation board designed at analog devices. Rs 578 00 433 mhz frequency around 100 meters range built in telescopic antenna keypad slide type protection cover ev1527 chip based protocol. To measure weight using load cell we usually need regulated power source output amplifier noise reduced adc converter. All three features need three separate circuits and components adding to cost and complexity.

Hx711 is a precision 24 bit analog to digital converter adc designed for weigh scales and industrial control applications to interface directly with a bridge sensor load cell strain guages. Hx711 soic16 24 bit adc ic for load cell. Load cell 40 kg. The load cell can be directly interfaced to this adc.

The ads1231 is a precision 24 bit analog to digital converter adc. Also you can observe from the circuit diagram that we power the load cell from the hx711 chip. With an onboard low noise amplifier onboard oscillator precision third order 24 bit delta sigma modulator and bridge power switch the ads1231 provides a complete front end solution for bridge sensor applications including weigh scales strain gauges and load cells. It interface with simple digital i o to any controller.

It consists of an ad7799 adc controlled by an aduc847 microcontroller. How to use hx711. When we apply weigh on the load cell it produces an. Hx711 soic16 24 bit adc ic for load cell.
