Product Description

1. Application

Equipped with a knife-edge junction directly welded to the furnace tube surface, suitable for measuring the surface temperature of petroleum industrial furnace tubes and tower walls. It is an essential temperature measuring device for distillation towers in refineries.

2. Main Technical Parameters

• Electrical Outlet: M20×1.5, NPT 1/2

• Accuracy Class: Class I or Class II

• Protection Grade: IP65

• Nominal Pressure: 10 MPa

• Enhanced Thermal Contact Efficiency：The knife-edge or blade-shaped sensing tip is designed to maximize surface contact with the boiler tube, ensuring rapid and accurate temperature measurement of the pipe wall.

• Non-intrusive Surface Measurement：No need to penetrate the tube wall—provides reliable surface temperature readings without affecting pressure integrity or structural safety of the boiler tube.

• High-Temperature Resistant Design：Built with high-grade stainless steel or Inconel sheath and mineral insulated (MI) cable, it withstands continuous operation in high-temperature environments common in boilers and furnaces.

• Quick Response Time：The blade-style design combined with direct surface contact allows for fast thermal response, improving control loop performance and safety monitoring.

• Simple Installation and Maintenance：Compact form factor and optional spring-loaded clamps or welded brackets make installation easy and secure. Designed for easy replacement and minimal downtime.

• Ideal for Power Plants and Petrochemical Boilers：Especially suitable for temperature monitoring of boiler tubes, reheaters, superheaters, and furnace walls in thermal power stations, petrochemical plants, and refineries.

• Customizable Configuration：Available in various sheath diameters, lengths, and mounting styles to meet the specific needs of different boiler systems and layouts.
