SEN 10245 not registering resistance change when load applied

I’ve bought 12 SEN 10245 sensors (2 for a project, then a further 10 to try to find 2 that work), and I cannot get them to work. I have tried testing the resistance while applying a load and none of them register a resistance change. I have my multimeter connected to the black and white wires and get a reading of around 1950 ohm. When I apply pressure to the sensor there should be a slight change in resistance but so far none of them work.

This video shows the method I am using to test the sensors:

I also have an HX711 amplifier to connect these sensors to my arduino but cannot get a signal when running the calibration sketch.

Can anyone tell me if I’m doing something wrong? It seems unlikely that all 12 sensors do not work.

Try connecting to the red wire and either the black or white wire. One of the two should show a change in resistance, but it’s a very small change and you’re going to need a good multimeter to detect it.
