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.
