Smart Temperature Transmitter KRC-T644

Smart Temperature Transmitter Model: KRC-T644 instrument Information: KRCsenT644 intelligent temperature transmitter is a powerful, wide application, two lines of microprocessor-based process control system designed for smart temperature transmitters. He can be used with a variety of temperature sensors, load sensors and potentiometers together. KRCsenT644 smart temperature transmitters for different measuring ranges and various types of sensors, such as: a variety of RTD and thermocouple, mV or ohm signal. Thus, the original installation in the field of different types of specifications of the temperature transmitter can be replaced by a unified KRCsenT644. This will significantly lose short calibration, maintenance and training time, reducing the need for spare parts, but also when buying KRCsenT644 do not need prior knowledge of measurement and control parameters. Input and output signal isolation with superior resistance to electromagnetic, RFI immunity. KRCsenT644 two-wire temperature transmitter can output with different temperature ranges to certain 4-20mA signal proportional relationship, and to KRCsenT644 smart temperature transmitters with digital communication via handheld terminal (KRC-PDA) or computer local or remote parameter adjustment. Keys can also be used to adjust the parameters of the instrument itself. KRCsenT644 intelligent temperature transmitter with explosion-proof, waterproof sealed enclosure, intrinsically safe, suitable for use in hazardous areas. Users can also choose not to use digital communication, the KRCsenT644 smart temperature transmitters only use as a traditional analog transmitter.
