Measurement Application

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.

Gasket-mounted surface temperature sensor installed at a bolted industrial pipe flange
Application Overview

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.

Measurement Objective

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.

Operational Value

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.

Measurement Technology

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.

Installation Context

Typical operating locations

  • Suitable flanged process connections
  • Piping and equipment interfaces
  • Compressors, turbines, pumps, and rotating equipment
  • Boiler, steam, and thermal-process connections
  • Industrial furnaces and process equipment
  • Retrofit and troubleshooting applications
  • Project-specific machinery and plant systems
Selection Guidance

Instrument-selection considerations

  • Flange standard, size, rating, and gasket design
  • Pressure, temperature, process medium, and materials
  • Sealing responsibility and mechanical approval
  • Required relationship to surface or process temperature
  • Sensor type, response, insulation, and electrical isolation
  • Cable routing, strain relief, termination, and protection
  • Installation torque, procedure, inspection, and replacement

Frequently Asked Questions

Application questions.

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.
