Integral drilling thermocouples are mostly used in installations that do not allow the use of large-diameter protective tubes, high pressure or abrasion due to installation conditions. The temperature sensor protective tube blind hole processing technology can increase the wall thickness of the protective tube of the same diameter Need for use. The integrally drilled thermocouple is assembled by a metal rod high-concentricity blind hole processed integral thick-walled outer protective tube and armored thermocouple temperature measuring element.
Due to production process constraints, most domestically can only provide users with a length of less than 500mm, beyond which the blind hole concentricity cannot be guaranteed. After several years of technological exploration and equipment adjustment, Changhui Instrument has become one of the few domestic manufacturers that can provide users with high concentricity sensor protection tubes with a length greater than 1000mm. Changhui Instrument provides users and peers with a total length of 1500mm high concentricity sensor integral drilling protection tube. The overall thermo-drilled thermocouple and the assembled thermocouple are the same in appearance and weigh a lot, but the measurement process of the measurement end of the integral-drilled thermocouple is different from that of the ordinary assembled thermocouple, as shown in the following figure:
Note 1: If the thermocouple uses a fixed flange or a non-standard thread installation method, the user must provide the thermocouple flange specifications, flange material or thread requirements according to the site matching flange requirements when ordering.
Note 2: The user has special requirements for the installation method of the integral drilled thermocouple, which requires a text description.
