Feature
Working Principle：
The change of the thermoelectric potential (resistance) measured by the thermocouple (resistance) in
the working state will generate an unbalanced signal through the bridge of the temperature transmitter, and after amplification,
it will be converted into a 4-20mA DC signal or a switch signal for work. instrument, the working instrument will display the corresponding temperature value.
Product Applications：
1. Electric Power: Generator set, Steam boiler
2. Petroleum: Reaction Tower, Distillation Tower, Laboratory Fluid Bed Dryers
3. Chemical: Production of Chemical Fiber Raw Materials
4. Grain: Vegetable Greenhouse
5. Food: Boiler, Steam Pipeline, Edible Oil Processing
6. Medical: Incinerator
7. Water Conservancy: Condensated Water
8. Test Equipment: Temperature Test
9. Metallurgy: Forged Steel, Smelting Process
Product Features：
1. 2-wire Output 4~20mA
(HART protocol or 485 protocol can be superimposed), 1~5V output and Switch Signal
2. Good Anti RFI
3. Cold end temperature automatic compensation
4. Wide Measurement Temperature Range(-200~1200℃)
5. High Mechanical Strength, Good Pressure Resistance
6. Laser Marking Technology to Ensure Traceability of Product
