We currently have the following part in stock:

  • HK43868

If your asphalt plant uses Hauck/Honeywell burner controls and you need a replacement stack thermocouple, Motion Engineering can help confirm availability and support your parts order.

In-Stock TC200-AJ Stack Thermocouple

The HK43868 Type J thermocouple is associated with the TC200-AJ stack thermocouple used in asphalt plant burner applications. Unlike a material thermocouple, which monitors material temperature, a stack thermocouple is typically used to monitor exhaust or stack temperature within the burner system.

Key details include:

  • Part Name: TC200-AJ Stack Thermocouple
  • Part Number: HK43868
  • Type: Type J
  • Application: Stack temperature sensing
  • Common Use: Hauck/Honeywell and Hauck/HTS asphalt plant burner systems

Stack temperature readings can help operators identify how the burner system is performing during production. When this part needs replacement, having the correct thermocouple on hand can help maintenance crews respond quickly.

Type J Stack Thermocouple for Asphalt Plant Burner Systems

A Type J stack thermocouple provides temperature feedback from the stack area of the burner system. This gives plant operators and control systems important information tied to burner operation, heat output, and exhaust temperature monitoring.

The TC200-AJ is intended for stack temperature sensing in asphalt plant applications where this part is specified. Before ordering, we recommend checking your existing part number, system documentation, or burner control parts list to confirm that HK43868 is the correct replacement.

Why Asphalt Plants Keep Stack Thermocouples in Stock

Stack thermocouples are often kept with other burner control spare parts because they support temperature monitoring during production. If a thermocouple fails or starts giving unreliable readings, it can make troubleshooting more difficult for plant maintenance teams.

Keeping the right spare thermocouple available can help reduce delays when a replacement is needed. For asphalt plants that rely on Hauck/Honeywell burner systems, having HK43868 in stock can be useful for planned maintenance, seasonal startup, or unexpected part replacement.

Frequently Asked Questions About TC200-AJ Stack Thermocouples

The TC200-AJ is a Type J stack thermocouple used for stack temperature sensing in asphalt plant burner systems.

The part number listed for this TC200-AJ stack thermocouple is HK43868.

No. A stack thermocouple is used for stack temperature sensing, while a material thermocouple is used for material temperature sensing. Both may be used in asphalt plant burner systems, but they serve different monitoring needs.
