If you can wheedle the specs. on this device from the manufacturer's receptionist you can search for some equivalent thermistor. You probably need the resistance at two temps and whether it a negative or positive tempco thermistor.
I got a small generic lamp for 32¢ for which the manuf. wanted $32 because the customer service lady read me the specs wanting to make sure she was selling me the correct lamp.
Or, if you have a schematic for the electronics that mates with this device, we might reverse engineer it.
Maybe these guys can cross reference it
If you say you need it to build an engineering prototype they may send you a free sample of the correct device.
