Metals & Heat Treat Temperature Sensors

Heat treat and metals processing demand sensors that hold performance at elevated temperature while supporting survey, control, and product-quality requirements. Thermometrics supports furnace, kiln, oven, forge, and high-heat process work with thermocouples, protection hardware, and calibration-driven builds.

Heat-Treat Operations

Survey and control sensing in furnaces, kilns, and high-heat process zones

Noble-metal probes, protection tubes, mineral-insulated thermocouples, and profile sensors are used in furnaces and heat-treat systems where survey work, control accuracy, drift behavior, and high-temperature durability directly affect product quality.

Common Applications

Furnace zones, work chambers, and process control points
Load, control, and survey thermocouples for heat-treat operations
Kilns, quench systems, and high-temperature material processing
Reformer, heater, and tube-skin style monitoring points

Sensor Solutions

Type K, N, R, S, and B thermocouples for base-metal and noble-metal service
Protection tubes, ceramic hardware, and MI cable constructions for severe heat
Replaceable-element and field-serviceable assembly options where practical
Calibration support for survey, validation, and repeatability-focused programs

Quality & Compliance

Heat-treat programs often reference AMS 2750 or CQI-9 practices, with sensor type, calibration interval, documentation, and thermocouple selection requirements driven by the furnace class, temperature range, and process criticality.

Survey & Control

Sensor builds for furnace control, load, and survey requirements.

Severe Heat

Protection tubes, ceramic hardware, and MI constructions for elevated temperature.

Calibration Workflow

Documentation and recertification support for thermal process programs.

Program Considerations

Heat treat work often depends on consistent thermocouple selection, replacement practice, and calibration discipline.
Protection hardware and serviceable assembly design become more important as heat, cycling, and contamination rise.
The right sensor package depends on whether the point is for control, product load, or periodic survey work.
