Power Generation —Turbine & Boiler Sensors

Thermometrics supplies temperature sensors for steam generating stations, gas turbines, cogeneration facilities, and standby power installations. Sensors are engineered for the extreme temperatures, pressures, and cyclic loading of power plant environments.

Steam Turbine & Feedwater

RTD and thermocouple assemblies for steam inlet, extraction, and exhaust temperature measurement. Feedwater heater RTDs per ASME PTC 12.1. High-pressure flanged thermowells for main steam lines above 600 PSI.

  • Duplex (measuring + backup) configurations
  • Flanged thermowells to ANSI 2500#
  • ASME PTC 19.3 calculations on request

Gas Turbine EGT / TIT

Exhaust gas temperature and turbine inlet temperature sensing assemblies. MIMS Type K and Type N thermocouples in Inconel sheath. Duplex elements for redundancy. Combustor liner thermocouples for plant DCS integration.

  • Type K or N, MIMS construction
  • Inconel 600 or 625 sheath
  • Spring-loaded for hot-section insertion

Boiler & Heat Recovery

Boiler drum, superheater, and reheater temperature sensors. Tube-skin thermocouples for monitoring tube-metal temperature in the radiant and convective sections. RTDs for economizer and air preheat temperature measurement.

  • Tube-skin weld-pad thermocouples
  • MIMS extension cable for furnace routing
  • Type K, N, or T for low-temperature sections

Bearing Temperature (API 670)

Journal and thrust bearing temperature sensors per API 670. Pt100 RTD, 3-wire, with spring-loaded element and stainless case. Meets OEM turbine-generator bearing monitoring specifications for major GE, Siemens, and Alstom turbines.

  • API 670 compliant specifications
  • Spring-loaded tip, 0.375" to 0.750" travel
  • Case styles A–D available
