SM9715 Thermocouple Protection Tube

Thermocouple Protection Tube Description

The Thermocouple Protection Tube, constructed from silicon nitride (Si3N4), is used to safeguard thermocouple sensors from high thermal stresses. Its chemical inertness and thermal shock resistance ensure that sensor measurements remain stable even under rapid temperature fluctuations. Engineered with precise dimensional tolerances, the tube fits standard thermocouple assemblies while its monitored microstructure supports long-term performance in heat-intensive environments.

Thermocouple Protection Tube Applications

1.       Industrial Applications
- Used as a protective casing in furnace controllers to achieve consistent temperature readings by leveraging its thermal shock resistance.

2.       Laboratory Equipment
- Applied as a sensor enclosure in research thermocouples to maintain measurement accuracy by leveraging its chemical inertness.

Thermocouple Protection Tube Packing

The Thermocouple Protection Tube is individually packed in moisture-resistant, anti-static pouches and secured within cushioned containers to minimise mechanical impact. It should be stored in a cool, clean environment to reduce dust contamination and preserve its microstructural integrity. Secondary sealed packaging further prevents exposure to humidity and particulate matter. Custom labelling and container size options are available upon request for bulk orders.

Frequently Asked Questions

Q1: What processing steps ensure the dimensional accuracy of the Thermocouple Protection Tube?
A1: The tube undergoes precision sintering and is inspected using scanning electron microscopy (SEM) to confirm consistent microstructure and dimensions. These steps are critical in maintaining its performance under thermal stress.

Q2: How does the silicon nitride composition contribute to the tube's thermal performance?
A2: Silicon nitride (Si3N4) offers chemical inertness and high thermal shock resistance. These properties help maintain sensor integrity by ensuring that the tube performs reliably even amid rapid temperature variations.

Q3: What storage conditions are recommended to preserve the tube’s properties?
A3: It is recommended to store the tube in a controlled, low-humidity environment at moderate temperatures. Using moisture-resistant, anti-static packaging minimises contamination and mechanical damage, thus preserving its microstructural integrity over time.
