The Formula for 1106 Force Sensor

[Kyle]

Hi there,

It's my first time using the sensor 1106. I 've looked up the produck manual. It mentioned the sensor is not for accurate force measurement but I didn't find the formula mapping the analog output with the actual force in Newton. Does anybody know it?

Another minor question, the user guide mentioned that

The sensor is not designed to have force applied constantly over time.

Does it mean if I keep pressing the sensor for a while, it will broken?

Here's the link for the sensor:

Thank you for your help!

In short, yes. The sensor is not designed to have force applied continually (constantly), it will damage the membrane and/or alter characteristics of the device. This is more-so notable at high force levels. It's meant to be used as a button or human interface, not as a weight measurement device.

Oh and to answer your other question, there is no formula for the 1106. It is not intended as an accurate or measurable force value in newtons. It is more-so meant for relative force measurements, ie when not pressed, reads ~0V/V; when pressed, reads something not 0V/V, up to 1.0V/V.

Thank you, Fraser! It's really helpful!
