Product Introduction         

Series WZ(R)B temperature transmitter is a kind of modularization two-wire transmitter. It can be directly installed in the thermal resistance and thermocouple junction box. It directly amplifies and converts the temperature signal measured by the temperature element into standard 4~20mA current signals and transmits them to the fiduciary instrument of the lower level. The thermocouple temperature transmitter eliminates the need for expensive compensation wire. The users don’t have to consider the cold junction compensation. The lead resistance compensation is not needed for the thermal resistance transmitter. The transmitter module has a linearizer whose output current is proportional to the temperature. The transmitter module is shock-proof, moisture-proof and corrosion-proof. It can be widely used for the temperature detection and control of petroleum, chemical, metallurgy, electric power, paper, food processing, casting, heating treatment and research department.
