Type S Thermocouple (PtRh10/Pt) – Ceramic Protected (Up to 1600°C)

A Type S thermocouple (PtRh10/Pt) is widely used in high-temperature furnace applications where long-term stability and repeatable measurements are critical. This page summarizes typical use cases, selection criteria, and the key details needed for a fast quotation.

Where Type S Thermocouples Are Used

Industrial furnaces (ceramics, glass, metallurgy, heat treatment)
High-temperature process monitoring over long operating cycles
Applications requiring stability and accuracy at elevated temperatures

Key Features

PtRh10/Pt sensing element for stable measurement at high temperatures
Ceramic protection for improved resistance in furnace environments
Probe dimensions and mounting options suitable for industrial installation
Custom production available based on your application

Selection Guide

Correct selection depends mainly on these factors:

Element / probe diameter: affects response time and durability (choose a more robust option if thermal shock or vibration is expected).
Ceramic sheath / protection: should match the process atmosphere (oxidizing/reducing) and any chemical vapors or gases.
Probe length (immersion): select according to the measurement point and mounting; insufficient immersion may reduce accuracy.

Mounting & Connection Notes

Select the mounting type (fitting/flange/head/terminal, etc.) according to your installation.
For long-term high-temperature use, periodic verification/calibration is recommended due to potential drift.

Price & Quotation Criteria

Type S thermocouple pricing depends on temperature range, probe dimensions, protection structure and connection hardware. To receive a fast and accurate quote, please share the following:

Maximum temperature and application type (furnace, glass, metallurgy, etc.)
Process atmosphere (oxidizing/reducing) and any chemical vapor/gas information
Probe length, sheath diameter, and mounting method
Preferred connection type (terminal block/connector/terminal box)

Frequently Asked Questions (Shipping & Sales)

Do you manufacture custom sizes (length/diameter)?: Yes. For non-standard dimensions, you can add a note to your order or send a technical drawing. Custom production is available depending on the application.
When will my order be shipped?: In-stock items are typically shipped the same day or the next business day. Lead times for custom production may vary depending on the product type and quantity.
Is there an exchange/return if I choose the wrong product?: Return/exchange conditions apply for standard products. Different conditions may apply for made-to-order or custom-produced items.
