We present here preliminary results for superconducting NbSi thermometers to be used in TES devices. These thermometers are being made by the CSNSM/IN2P3 in Orsay, France, in parallel to resistive NbSi thermometers, a more common use for this alloy. The critical temperature of these devices is easily tuneable. We present here devices operated and tested at 300 mK using a 3He fridge.
