Usually with manifestation appearance,record appearance,computer etc. kit usage, output a 4-20 mAs.Measure various production line directly in of-200 ℃～s 1300 the ℃ liquid,steam inside the scope the friendly body lie the quality and solid surface temperature.
Characteristics
●Two lines systems output a 4-20 mAs, the anti- interference ability is strong;
●The economical repair leads line and installs temperature to change to send the machine expenses;
●Measure scope big;
●Cold carry the temperature auto in expiation of, not the line correct electric circuit.
The work principle
Separate to explode thermocouple to make use of cleft to separate to explode principle, be When the occurrence in the explode, can pass a coalescence the noodles cleft to turn off with the cooling, make the temperature of the flames of explode the empress could not spread the outside of the , Be thus carry on measuring.Hot electricity power(electric resistance) the process temperature that the thermocoupleproduce changes the electricity bridge creation unbalance signal of send the machine, converting direct current signal of become the 4-20 mAs to give after enlarge the work appearance, work the gauge display then to should of temperature value.

The ○ outputs signal:4-20 mAs, the load electric resistance is 250 Ωs, delivering to lead the line electric resistance 100 Ωs.
The ○ outputs a method:Two lines systems
○ Accuracy grade:
●The temperature changes to send the machine accuracy grade:0.1;0.2;0.5;
●Display accuracy:The emulation indicates 2.5 classes;The numeral shows 1.0 classes.
○ Power supply power supply:24V.10% of DC ±
○ Protection grade:IP65
○ Flameproof grade:
Separate to explode a form:DIIBT 4, dIICT 5, dIICT 6
Essence safe form:iaIICT6
The ○ insulates electric resistance:
The gauge exportation's connecting a that the line carries son and outer shell to insulate electric resistance should be no smaller than 50 M Ω .
The ○ heat responds to time:
When the temperature appears a rank to jump variety, the electric current of the gauge outputs time that 50% that the signal changes to equal to that rank to jump variety need, usually with τ 0.5 mean being temperature changes a rank of send the machine to jump to respond to stable time and doesn't exceed the thermocouple heat to respond to stable time τ 0.5 of five divide it at that time, then respond to time as gauge with the thermocouple heat of hot ring time;
When the temperature changes a rank of send the machine to jump to respond to stable time and doesn't exceed the thermocouple heat to respond to stable time τ 0.5 of two divide it at that time, then change to send to the machine heat to respond to time as the heat of the gauge to respond to time with the temperature.
○ Basic error margin
The basic error margin of the gauge should not exceed thermocoupleto change to send the machine basic error margin to synthesize an error margin with temperature.
