New Launch Of S-Type Precious Metal Thermocouple: Accurate High-Temperature Measurement For Severe Industrial Environments

May 20, 2026 Leave a message

Our newly launched S-type PtRh10-Pt thermocouple is specially developed for harsh high-temperature industrial scenarios, delivering accurate, stable and dependable temperature measurement.

Working based on the Seebeck effect, this thermocouple converts thermoelectric force generated by temperature difference between positive PtRh10 alloy electrode and negative pure platinum electrode into standard 4-20mA signals via integrated transmitter modules. It can be directly connected to PLC and DCS systems to realize real-time collection and control of high-temperature data.
