TxIsoBlock-HRT


HART® Temperature Transmitter

Temperature transmitter TxIsoBlock-HRT combines the proven quality of HART® certification with the robustness of NOVUS devices. The transmitter is compatible with HART® certified devices and it has electrical isolation between input and output, supporting voltage surges up to 1.5 kVrms. Its great differential is the total configuration through the two 4-20 mA current loop wires, which means more features for device configuration and monitoring.

 

By using a worldwide known protocol with more than 40 million field instruments supporting HART® technology, NOVUS's temperature transmitter TxIsoBlock-HRT enables the use of standard HART® configuration and supervision software that provides flexibility to users.

    Article: The HART Communication Protocol

    Communication with machinery and control and measuring instruments is the basis of industrial automation. The oldest communication technique implemented is a current loop with a normal range of 4 mA to 20 mA. By employing a transmitter, a receiver and a power supply, it is possible to transmit process variable data. However, the single loop allows only one-way communication from a sensor to an actuator. Developed in the mid-1980s, the HART protocol allows two-way communication of additional information
