1. Basic information
Model: 297A0581P005
Type: Industrial grade armored thermocouple (usually K or E type, subject to nameplate)
Purpose: High temperature process monitoring, dedicated to real-time temperature measurement of energy equipment such as gas turbines, steam turbines, boilers, etc.
2. Key characteristics
Parameter Description
Temperature measurement range -40 ° C~+1200 ° C (depending on the type of thermocouple, the upper limit of K-type is about 1300 ° C)
Accuracy level ± 1.5 ° C or ± 0.4% t (t is the measured temperature value, in accordance with IEC 60584 standard)
Sheath material Inconel 600/601 (nickel based alloy, resistant to high temperature corrosion and mechanical impact)
High purity magnesium oxide (MgO) insulation material, moisture-proof and high temperature resistant
Protection level IP65 (dustproof and waterproof)
Response time
3. Structural design
Armor structure:
Metal sheath+mineral insulation layer+thermocouple wire integrated die-casting, resistant to vibration and high voltage.
Flexible or rigid rod body, supporting bending installation (minimum bending radius ≥ 5 times the diameter of the sheath).
Interface type:
Standard thread installation (such as 1/4 "NPT or M16 × 1.5)
Optional junction boxes: explosion-proof, waterproof, or high-temperature (usually made of aluminum alloy/stainless steel).
4. Typical application scenarios
Gas turbine: Monitor the outlet temperature of the combustion chamber and the temperature of the bearings.
Steam turbine: temperature monitoring of main steam pipeline and reheater.
Industrial boilers: measurement of furnace temperature and flue gas temperature.
Applicable industries: electricity, petrochemicals, metallurgy.
5. Key points for installation and maintenance
Installation location:
The temperature measurement point should avoid turbulent areas and be inserted at a depth ≥ 15 times the diameter of the sheath to ensure accuracy.
The threaded area needs to be coated with high-temperature sealant to prevent leakage (such as Nickel Anti Size recommended by GE).
Troubleshooting:
Reading drift: Check for thermocouple wire oxidation or sheath rupture (replacement required).
Signal loss: Verify that the terminal of the junction box is loose or the compensating wire is broken.
Calibration cycle: It is recommended to calibrate the high temperature point once a year (such as using a tube type calibration furnace).
6. Compatibility and Alternative Solutions
Category Description
The GE system is compatible with analog input modules that can be directly connected to Mark VIe and TX control systems (such as the IS200 series).
Directly replace the same series model 297A0581P001 (length/interface may be different).
Cross brand replacement of Omega KMQSS-125U and Honeywell TK-T series (parameter matching needs to be verified).
