Integrated status display temperature transmitter specification

1.  summary:

  The temperature transmitter is small integrated two-wire temperature transmitter with display、loop power supply .It received input signals from the thermal resistance/thermocouple which has the normal graduation number, and produced normal DC output signals (4-20mADC) which showed linearity with measured temperature, and make a survey of various local temperature and signal transmitter of realization. Its accuracy in measurement transmission range and interference is out match other congeneric temperature measuring equipment.

  The temperature transmitter companion with various secondary instrument or compute system, and realized   check  and control to local temperature. Wide used for petroleum、 chemical industry 、metallurgy、 generating plant 、light industry 、medicine etc. multifarious industrial department and research engineering.

2．Characteristic:

1)Temperature transmitter is the linearity circuit, its output DC signal relation with measured temperature is linearity. 

2)Transmitter adopt solidified encapsulation, corrosion attack ant vibration and wide usable ambient temperature range.

3)4-20mADC large signal current transmission, lesser transmission distortion, strong capacity of resisting disturbance, farther transmission distance.

4)Lesser quiescent dissipation, constructible intrinsically safe explosion protection system with guard  grating, immediate packing in hazardous location ,constructible explosion-proof transmitting system that mount in explosion-proof connection box.

5)Transmission adopt two-wire system and general copper conductor, may draw in the reins.

6)Flexible application, at locale, temperature transmitter strip digital readout meter reading temperature, companion use with regulator recorder display instrument. Isolation can go directly computer control system..

3. Technical Index:

1) Basic Accuracy:  Thermal resistance:≤±0.2%FS

                 Thermocouple: ≤±0.5%FS

2) Temperature Element: Thermal resistance: Pt100/Pt10/BA1/BA2/Cu50/Cu53/Cu100

                     Thermocouple:  K/E/S/T/J

3)Output signal:4-20mADC signal, and showed linearity with measured temperature, two-wire system transport.

4)Supply Voltage:24VDC,and have backward protection feature

5)Load Resistance(RL):Ensured under the condition of constant current, and output signal is 20mADC,relationship between load resistance(RL) and service voltage(VS) is: RL=Vs-12/0.02Ω,normal is 250Ω.

6)Ambient Temperature Effect: temperature per change 10℃,output change less than measurement range 0.1%,in the established ambient temperature.
