SBW intelligent integrated temperature transmitter
Description
SBW intelligent integrated temperature transmitter is used for thermal resistance (RTD), thermocouple (TC) sensor input, and its signal into the two-line system of 4~20mA DC current signal transmission to the display, recorder, PLC, DCS, etc., to achieve accurate measurement and control of temperature. Intelligent integrated temperature transmitter can be configured by HART protocol. It is the updating product of temperature measurement and control in modern industrial field and scientific research institutes, and it is the necessary product of distribution system and digital bus system. 1.
