  • Introduction
  • Specifications
DBW-5500A(Ⅲ)temperature transmitter is a mainly unit of DDZ-Ⅲ series instrument which used with all kinds of thermocouple and thermal resistor to convert temperature signal into 4~20mA DC signal. It also can be used as a Low-level millivolt DC Converter which completed with transmitter and output 4~20mA DC. user can choose 1~5V DC output. They are used with regulator and the actuator to form an automatic temperature-conditioning system.
