T-260/T-270Z has an excellent resistance against high temperature and high pressure. Moreover, T-270Z can measure resin temperature change even there are thermal disturbances because of its Zero-Heat-Flow structure. That leads to be stable resin temperature control. Because the barrel temperature will be transferred to the protection tube, traditional sensors negatively effects on their measurements. T-270Z realizes its accurate measurement of the resin temperature by compensating the barrel temperature.
