Product description

Characteristics

•The two-wire system transmitter, which is based on current loop power supply, can effectively reduce the wiring costs and power consumption and enhance the anti-interference ability.

• HART communication protocol.

• 4-20mA output.

• While connecting to the thermal resistance transducer, it has short-circuit and open-circuit monitoring function; while connecting to the thermocouple transducer, it has open-circuit monitoring function.

•By using the 3 built-in operating buttons together with the highlighted LCD display, the parameters of the transmitter can be set locally conveniently. In addition, the remote parameter configuration of the transmitter can be realized easily by HART modem.

•The rotatable LCD display enhances the flexibility of transmitter installation and displays the percentage of current measured value in the full scale, current measured value and its unit and the sensor type and the diagnostic messages of transmitter etc.

•The protection level of shell is IP67, which can be applied to the outdoor usage.

• Support all the transducers conforming to IEC751 and IEC584.

Technical parameters

Input

Sensor type:

301A/B1: Pt100, Pt1000, Cu50, Cu100

301A/B2: S, R, B, K, N, E, J, T, WRe3-25

301A/B3: Pt100, Pt1000, Cu50, Cu100

S, R, B, K, N, E, J, T, WRe3-25

Accept the user’s designation

Connection modes

301A/B1: A two/three/four-wire system thermal resistance transducer

301A/B2: A thermocouple transducer and a thermal resistance transducer (three-wire) can work as the cold junction compensation or set the fixed cold-junction temperature to compensate without connecting to the thermal resistance transducer, or use the built-in thermal resistance transducer of the transmitter to conduct cold junction compensation (The compensation precision will effect the final measurement accuracy.)

301A/B3: adopt the connection mode of 301A/B1 or 301A/B2 according to the needs
