Looking for force sensor replacement

[JerinG]

In one of our engineering projects we used force sensor provided by our customer. Data is in attachment. Because of sensor provider cancelation of further sensor delivery, we are looking for replacement. I'm asking for some recomendations for replacements if possible.

This sensor is normally used in robots (6 axis force and torque sensor), but in this application it was used for measuring forces and torques during bike pedaling, so this is our application of the sensor.
Sensor can't be larger because current version was installed in housing. We will probably have to redesign everything, but we know from experiences with development that dimensions and other requirements have to be in very close with what was used until now.

I'm still gathering information for all sensor's requirements. In last case and with enough resources we will try to develop our own sensor.
Any help and hints for something similar will be very usfeful. Thank you.

You would need a lot of resources and experience to design (copy) a 6-axis sensor! Why not find another sensor vendor?

Bing Search: robot 6-axis force sensor

It would seem you would have enough challenges with mechanical adapters, electronics, and software without the challenge of design-build the sensor.

It was already hard to find this sensor. As I said, I'm still gathering data, why. When we were designing the application, we just received the sensor information. Now we are trying to help our customer. As I said, making our own sensor is last resort if it will even be possible, because of lack of resources.
I will get back when I have more info on why they are so limited in sensor selection.

I got some more information. As I said, there were some limitations and requests when our customer choose this sensor amongst others.
1) Height x Diameter are only 35 x 70 mm.
2) Maximum compression force Fz is 2000 N and 400 N in tension. Fx and Fy are 400 N, Tx and Ty are 20 Nm and Tz is 13 Nm. All of these ratings are needed for application.
3) Price is afordable, which was around 2500 € per sensor.

Before the application was made, research was made amongst different manufacturers and this one was choosen. All other sensors were larger and had smaller force ratings. And were usually more expensive. Company was now sold under larger other company and sensor delivery was canceled.

Since the world is big I'm still asking if anyone has any info about these kind of sensors and if they exist on the market. We need to satisfy all three upper points - at least if not better.
