INDUSTRY COMPONENT

Sensing Element

Temperature sensing element for chemical reactor probes converting thermal energy to electrical signals.

Component Specifications

Definition
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.
Working Principle
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.
Materials
High-purity platinum (Pt100/Pt1000 RTDs), Type K/J/T thermocouple alloys (chromel-alumel, iron-constantan), ceramic substrates, mineral-insulated metal sheathing (Inconel 600/316L stainless steel), alumina or magnesium oxide insulation.

Frequently Asked Questions

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.
