Looking for small Wireless RTD's to replace wired RTD on moving gripper

Good Afternoon ,

I am looking for a stable small wireless RTD. We have a wired RTD on a gripper that moves during normal operation. We have a lot of problems with broken wires . I searched for wireless RTD's , but I seen were too big for our application. Have any of you seen any small wireless RTD's ?

Thanks so much n advance ,

On the gripper change the wiring to a good flexible type of wire with a crane cable, it may be any type of cable.
another way is to put the sensor on a stand and put the object against the sensor.
In most cases the resolution is not good enough.
a way could be to use arduino or an XTR105.
