Gasket-Mount Surface Temperature Measurement
Measure temperature at a suitable flange or gasket interface using an engineered thermocouple arrangement that avoids a conventional process penetration.
Surface and interface measurement through a gasket-mounted arrangement
Gasket-mounted surface thermocouples provide a project-specific way to measure temperature at a flange, joint, or equipment interface without installing a conventional immersed thermowell. The arrangement may be useful where process penetration is difficult, existing equipment must be adapted, or interface temperature is the measurement objective.
Suitability depends on the flange and gasket design, sealing responsibility, pressure, temperature, materials, compression, routing, mechanical loading, electrical isolation, installation procedure, and the relationship between interface temperature and the process information required.
What the application needs to establish
Measure temperature at a defined gasket, flange, or equipment interface with an engineered assembly that preserves the required mechanical and sealing arrangement.
Why the measurement matters
Non-intrusive arrangement
Obtain a temperature indication without a conventional immersed process connection where technically suitable.
Retrofit support
Add measurement to existing flanged equipment when a new nozzle or thermowell is impractical.
Equipment monitoring
Track interface, surface, or equipment temperature for operation and investigation.
Installation flexibility
Use a custom form, routing, and termination designed around the existing connection.
Maintenance insight
Identify changing thermal conditions at selected flanges or equipment interfaces.
How the measurement is approached
A thermocouple element is integrated into or positioned by a project-specific gasket-mounted arrangement. The measured temperature represents the local interface and must not be assumed to equal bulk process temperature without validation.

Does a gasket-mounted sensor measure the bulk process temperature?
Not necessarily. It measures the local interface or surface temperature. The relationship to the process temperature depends on the equipment, heat transfer, installation, and validation.
Can it be used on any flange?
No. Flange size, rating, gasket type, pressure, temperature, medium, sealing design, compression, materials, and mechanical approval must be reviewed.
Who is responsible for sealing integrity?
The project, plant, equipment owner, gasket specialist, and engineering authority must approve the final sealing and installation arrangement. The sensor design cannot be separated from that responsibility.
Is this a standard catalog item?
The BDT-GT is application engineered. Dimensions, materials, sensor type, routing, termination, and installation details are defined for the specific connection.
