Product brief introduction: DBW electric two-wire temperature transmitter belongs to DDZ- type electric unit combination instrument transmission unit, with the regulator, the actuator indicator, recorder can be composed of automatic adjusting circuit, or indicating circuit.

The transmitter for the on-site installation type.

Two wire transmitter by the output signal (4mA DC ) affect the lower limit generally no linear correction circuit, so the output of the transmitter only with the MV ( TC),△ R ( RTD ) proportional to. In order to realize the accurate temperature engineering quantity indication, the series and configuration of the two instrumentation ( controller, indicator, recorder ) scale is associated with the temperature measurement element mv ( or R) - temperature characteristics consistent.

Output signal:4～ 20mA

Precision: the input signal is greater than or equal to 5mV (△ R ≥10 Ω)0.5

3 mV (≤6Ω) input signal (△ R ) < 5( mV10Ω)1

1.5 mV (≤3Ω) input signal (△ R ) < 3( mV6Ω)1.5
