Preparations

Prepare the installation in good time by checking that the necessary documents and material are
available, as follows:
• Installation drawings and this manual.
• Standard tools, torque wrench and instruments.
• Rust protection, if additional protection is to be given to machined surfaces. Choose TEC-
TYL 511 (Valvoline) or FERRYL (104), for example.
• Load cells, adapter plates, bearing housings, etc.
• Screws as listed in Table 2. page 20
for bearing housing, etc.

Adapter Plates

The adapter plates for all load cell types in the PFTL 101 family must be machined and have a
flatness deviation of maximum 0.05 mm, required surface finish should be Ra 3,2.
For PFTL 101A the thickness of the adapter plates should be minimum 30 mm, and for PFTL 101B
35 mm, see Figure 15. Installation of Adapter Plates and Alignment of Load Cells page 21
Information
