1、 Overview: Integrated explosion-proof thermistor is usually used in conjunction with display instruments, recording instruments, electronic computers, etc., with an output of 4-20mA. It directly measures the temperature of liquid, steam, gas media, and solid surfaces within the range of 0-1800 ℃ in various production processes. The integrated explosion-proof thermistor can also be made into an integrated device with on-site display and 4-20mA output. 2、 Product principle: The integrated explosion-proof thermistor utilizes the principle of gap explosion-proof. When an explosion occurs inside the chamber, it can be extinguished and cooled through the gap between the joint surfaces, preventing the temperature of the flame after the explosion from being transmitted outside the chamber, thus enabling temperature measurement. The thermoelectric potential (resistance) produced by thermocouples (resistors) generates an unbalanced signal through the bridge of a temperature transmitter, which is amplified and converted into a 4-20mA DC electrical signal for the working instrument to display the corresponding temperature value. 3、 Product features: Two line output 4-20mA, strong anti-interference ability; Save the cost of compensating wires and installing temperature transmitters; Large measurement range; Cold end temperature automatic compensation, non-linear correction circuit. 4、 Technical parameters: 1. Execution standards: IEC584 IEC1515 IEC751 JB/T5518-91 JB/T7391-94 2. Explosion proof grade: Explosion proof form: dIIBT4, dIICT5, dIICT6 Intrinsic safety form: iaIICT6 3. Output signal: 4-20mA, load resistance 250 Ω, transmission wire resistance 100 Ω 4. Output method: Two line system 5. Tolerance level: 0.1; 0.2； zero point five 6. Power supply: 24V DC ± 10% 7. Protection level: IP65 5、 Selection Table
