Could This Be a Strain Gauge from My Disassembled Scale?

AI Thread Summary
The discussion revolves around the identification of a component from a disassembled electronic scale, suspected to be a strain gauge. The user notes that pressing on the component produces varying readings on the display and measures its resistance with a multimeter, showing values around 992 ohms, which change slightly with pressure. The component has three wires: red, black, and white, with questions about their functions. A response clarifies that the red wire is for supply, the black wire completes a half bridge, and the white wire is for signal output. The conversation emphasizes the need for clearer information and possibly a visual reference to enhance understanding.

I disassembled an electronic scale. I removed a piece from the corner. I think it is an strain gauge. When I Press on it a reading appears on The liquid crystal display. It might Say 9.6 or 10.8 or 11.5. I used a multimeter to measure it resistance. It 992 ohms. Unless I press on it. Then its 994 ohms or 995 ohms Or 998 ohms. Sometimes a little More than 1000 ohms. It has 3 wires What is the white wire for. It has a Red wire. It has a black wire. It has A white wire.

Is there a question in there somewhere? Also, why do your posts always seem to be just a few words per line? I don't see that with any other poster so I'm wondering what device/app you are using that seems to have that limitation (or do you just prefer to post that way?)
 
This is a poor question. Please provide some sort of graphic support for your description. A picture of the object will help. If the level of information does not improve we will have to close the thread. As is, it is very close to useless.

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
