Fixed flange Temperature transmitter


1. Application of Fixed flange Temperature transmitter

It is usually used together with display instruments, recording instruments, electronic computers, etc., and outputs 4-20mA to directly measure the gas quality of liquid and steam and the surface temperature of solid in the range of - 200 ℃ - 1300 ℃ where carbon and chlorine compounds exist on the production site.

2. Features of Fixed flange Temperature transmitter
Two wire system output 4-20mA, strong anti-interference capability;
Save the cost of compensating wire and installing temperature transmitter;
Safe and reliable, long service life;
Cold junction temperature automatic compensation, nonlinear correction circuit;

3. Working principle of Fixed flange Temperature transmitter
Explosion proof thermocouples use the principle of gap explosion-proof. When the cavity occurs, the flame can be extinguished and cooled through the gap of the joint surface, so that the full temperature of the flame can not be transferred to the cavity, so as to carry out explosion protection.

The thermoelectric potential (resistance) generated by the thermocouple (thermal resistance) generates an unbalanced signal through the bridge of the temperature transmitter, which is amplified and converted into a 4-20mA DC electrical signal to the working instrument, and the working instrument will display the corresponding temperature value.

Display accuracy class: analog indicator 2.5; Digital display class 0.5
8. Power supply: 24V. DC ± 10%
9. Protection grade: IP65
10. Explosion proof grade: explosion-proof type: d Ⅱ BT4 d Ⅱ CT5 d Ⅱ CT6 Intrinsically safe type: ia Ⅱ CT6
11. Insulation resistance: the insulation resistance between the instrument output terminal and the housing shall not be less than 50M Ω

12. Thermal response time:
When there is a step change in temperature, the time required for the current output signal of the instrument to change to 50% of the step change is usually expressed in t0.5. When the step response stability time of the temperature transmitter does not exceed one fifth of the thermal response stability time t0.5 of the thermocouple (resistance), the thermal response time of the thermocouple (resistance) is used as the thermal response time of the instrument; When the step thermal response stabilization time of the temperature transmitter does not exceed the thermal response stabilization time of the thermocouple (resistance) τ When it is half of 0.5, the thermal response time of the temperature transmitter is used as the thermal response time of the instrument;

13. Basic error: the basic error of the instrument shall not exceed the combined error of the basic error of thermocouple (resistance) and temperature transmitter.
