        詳細介紹


        Service intended

        T900 series temperature transmitters are designed to fit into a standard molded terminal heads used on RTD and thermocouple assemblies to provide a 4-20 mA transmission signals. It is a cost effective solution for all temperature measuring process. It is accurate, durable and reliable. Numerous configurations for measurement in many deferent mediums are offered. Generally the transmitter produces a linear 4-20 mA output carried on a two-wire system. The transmitter is supplied factory calibrated, but also has zero and span potentiometers for a field adjustment.

        Advantages ■ Two wire 4-20 mA current output signals
        ■ Universal input signals
           - RTD temperature sensor
           - T/C elements
           - mV, V, mA, DC signals
        ■Programmable function setting
          - Input signal type
          - Measuring range
          - Burnout Low/High setting
          - mA output offset
        ■ Excellent accuracy and a long term stability
        ■ Low cost effective
