TH56 Spare Parts List Overview
The TH56 spare parts list is an important basis for industrial instrument selection and procurement, used to clarify spare part specifications, connection methods, and additional requirements. Correctly understanding the ordering code structure can avoid selection errors and improve procurement efficiency.
This list applies to non-repairable units, and all spare parts must be ordered according to specific codes. The meaning of each code is analyzed section by section below.
Ordering Code Structure Description
The ordering code for the TH56 spare parts list consists of multiple code segments, representing ferrule thread, process connection, documentation requirements, version, and additional options. Each code segment corresponds to a specific specification, and when combined forms the complete ordering code.
Ferrule Thread and Process Connection Codes
The ferrule thread code is TU301-, followed by two letters indicating bore size and process connection. Bore sizes include 1/16", 1/8", 3/16", and 1/4". Process connections are NPT1/8 or NPT1/4, and the material is 316 stainless steel.
In the code, one time indicates one-time installation, and re-adjust indicates re-adjustable. See the table below for specific correspondences:
| Code | Bore Size | Process Connection | Material | Type |
|---|---|---|---|---|
| AA | 1/16" | NPT1/8 | 316 | one time |
| AC | 1/16" | NPT1/8 | 316 | re-adjust |
| BA | 1/8" | NPT1/8 | 316 | one time |
| BB | 1/8" | NPT1/4 | 316 | one time |
| BC | 1/8" | NPT1/8 | 316 | re-adjust |
| BD | 1/8" | NPT1/4 | 316 | re-adjust |
| CA | 3/16" | NPT1/8 | 316 | one time |
| CB | 3/16" | NPT1/4 | 316 | one time |
| CC | 3/16" | NPT1/8 | 316 | re-adjust |
| CD | 3/16" | NPT1/4 | 316 | re-adjust |
| DA | 1/4" | NPT1/8 | 316 | one time |
| DB | 1/4" | NPT1/4 | 316 | one time |
| DC | 1/4" | NPT1/8 | 316 | re-adjust |
| DD | 1/4" | NPT1/4 | 316 | re-adjust |
| YY | Special version, TSP number must be specified | |||
Documentation Requirements and Version Codes
Documentation requirement code 1 indicates standard documentation. Version code K indicates standard version. These codes are usually fixed unless there are special requirements.
Additional Options and Customer Customization
Additional option code 1 indicates not selected. Customer customization code Z indicates a special version, and a TSP number must be specified. If customization is required, please provide detailed specifications when ordering.
Selection Steps
To ensure correct ordering of TH56 spare parts, please follow these steps:
- Determine the required bore size and process connection, and select the corresponding code from the table (e.g., AA, BC, etc.).
- Confirm the installation type: one-time installation or re-adjustable.
- Check the documentation requirements and version codes, usually 1 and K.
- If there are special requirements, select the additional option or customer customization code, and provide the TSP number.
- Combine all codes to form the complete ordering code.
Notes
- This unit is non-repairable; please order according to the spare parts list.
- All threaded connections are made of 316 stainless steel, suitable for corrosive environments.
- Codes YY and Z require a TSP number; otherwise, ordering is not possible.
- If you have any questions, please contact technical support to confirm the code combination.
