Thermocouple and RTDs with Solid Drilled Thermowell

Thermocouples and RTDs featuring solid-drilled thermowells are high-precision temperature sensors engineered for demanding industrial conditions characterized by high pressure, intense vibration, strong erosion, and strict sealing requirements. Moving away from traditional welded thermowell designs, these products utilize a thermowell formed from a single solid metal rod via precision drilling—creating a blind hole with high concentricity. Paired with armored sensing elements and standardized connection structures, the seamless, integrated design eliminates common industry issues such as weld cracking, insufficient pressure resistance, sluggish response times, and leakage. Combining the wide temperature range capabilities of thermocouples with the high precision of RTDs, these sensors serve as critical components for accurate temperature measurement and stable control in heavy industry, making them suitable for a wide variety of complex industrial applications.
Solid-Drilled Thermowell Thermocouples: Based on the thermoelectric effect, these sensors offer an exceptionally wide measurement range—from -40°C to 1600°C—making them ideal for high-temperature and ultra-high-temperature industrial environments. They exhibit excellent heat and thermal shock resistance, maintaining superior stability during rapid temperature fluctuations without drift or failure.
Solid-Drilled Thermowell RTDs: Operating on the principle of linear resistance change relative to temperature, these sensors deliver superior precision, stability, and repeatability. With minimal measurement error in low- to medium-temperature ranges, they are perfectly suited for precision manufacturing processes that demand strict accuracy and data stability, meeting rigorous standards for process temperature control.
Thermocouple and RTD specifications—including diameter, insertion length, and calibration type—can be customized to meet specific application requirements.
