定义
A precision temperature sensing element integrated within chemical reactor temperature sensor probes that detects thermal variations in reactive environments and converts them into measurable electrical signals through thermoelectric or resistive principles, enabling real-time process monitoring and control.
工作原理
Operates on the Seebeck effect (thermocouples) or temperature-dependent resistance change (RTDs/thermistors) where thermal energy from the reactor medium creates voltage or resistance changes proportional to temperature, transmitted to signal conditioning circuits.
材料
High-purity platinum (Pt100/Pt1000 RTDs)Type K/J/T thermocouple alloys (chromel-alumeliron-constantan)ceramic substratesmineral-insulated metal sheathing (Inconel 600/316L stainless steel)alumina or magnesium oxide insulation.
Accuracy
±0.1°C to ±1.5°C
Output Signal
mV (thermocouple) or Ω (RTD)
Response Time
0.5 to 5 seconds
Pressure Rating
Up to 100 bar
Protection Rating
IP67/IP69K
Temperature Range
-200°C to +850°C
标准
ISO 6708DIN 43735IEC 60751

常见问题

What is the difference between RTD and thermocouple sensing elements?

RTDs use platinum wire resistance changes for higher accuracy (±0.1°C) in moderate ranges (-200°C to 850°C), while thermocouples generate voltage via dissimilar metals for wider ranges (-270°C to 2300°C) with slightly lower accuracy (±1.5°C).

How are sensing elements protected in corrosive chemical environments?

Through Inconel or 316L stainless steel sheathing, ceramic insulation, and hermetic sealing that prevent chemical penetration while maintaining thermal conductivity.
