定义
A critical component of molten metal temperature sensor probes that serves as the interface between the sensitive thermocouple or RTD element and external instrumentation. It provides mechanical protection, electrical connection integrity, and environmental sealing while maintaining thermal isolation from the harsh molten metal environment. The connection head typically houses terminal blocks, compensation circuits, and sealing mechanisms to ensure accurate temperature measurement transmission.
工作原理
The connection head functions as an interface module that converts the millivolt signals from thermocouples or resistance changes from RTDs into stable electrical signals for transmission to temperature controllers or data acquisition systems. It incorporates cold junction compensation for thermocouples, signal conditioning circuits, and provides mechanical strain relief for connecting cables while maintaining electrical isolation and environmental protection.

常见问题

What is the maximum ambient temperature for connection heads in molten metal applications?

Connection heads are typically rated for ambient temperatures up to 200°C, though the sensor tip can withstand much higher temperatures (up to 1800°C for some thermocouples). The head must be positioned sufficiently distant from the molten metal to prevent overheating.

How often should connection heads be inspected in continuous casting operations?

Monthly visual inspections are recommended, with complete functional testing every 6 months. In high-vibration environments or with frequent thermal cycling, inspection frequency should increase to quarterly.

Can connection heads be used interchangeably between different sensor manufacturers?

While some standardized connections exist (M12, NPT), electrical pin configurations and compensation circuits may vary. Always verify compatibility with specific sensor types (Type K, R, S thermocouples or specific RTD types).
