?稱重傳感器的基礎(chǔ)必須盡可能穩(wěn)定。堅(jiān)固的結(jié)構(gòu)降低測(cè)量輥和軸承裝置的振動(dòng)能量。
?最靠近稱重傳感器的表面以及影響配合的其他表面必須進(jìn)行機(jī)械加工fl@t至0.05mm以內(nèi)。
?稱重傳感器上方或下方不得有任何墊片，因?yàn)榭赡懿焕绊慺l@tness相反，墊片可以放置在適配器板和基座或適配器板和軸承箱之間。
?固定稱重傳感器的螺釘必須用扭矩扳手?jǐn)Q緊。
?測(cè)量輥的軸承布置必須設(shè)計(jì)為允許軸向膨脹：隨溫度變化的輥。
?對(duì)輥施加任何驅(qū)動(dòng)時(shí)，必須確保來自驅(qū)動(dòng)的干擾力：保持在最小值。
?測(cè)量輥必須動(dòng)態(tài)平衡
?稱重傳感器的安裝表面必須位于同一高度，并與測(cè)量輥。
?在腐蝕性環(huán)境中，稱重傳感器之間可能發(fā)生電偶腐蝕，鍍鋅螺釘和轉(zhuǎn)接板。這就需要使用不銹鋼螺釘以及不銹鋼或同等材料的轉(zhuǎn)接板。參見圖紙中的適配器板。

3.4轉(zhuǎn)接板
PFTL 101系列中所有稱重傳感器類型的適配器板必須經(jīng)過加工，并具有fl@tness最大偏差為0.05 mm，要求的表面光潔度應(yīng)為Ra 3.2。
對(duì)于PFTL 101A，轉(zhuǎn)接板的厚度應(yīng)至少為30 mm，對(duì)于PFTL101B35 mm，見圖15。適配器板的安裝和稱重傳感器的校準(zhǔn)第21頁信息
當(dāng)安裝PFTL 101AER和PFTL 101 BER時(shí)，必須使用奧氏體鋼的適配器板，優(yōu)選耐酸或不銹鋼。
? The foundation for the load cell must be made as stable as possible. A sturdy construction
reduces the vibration energy of the measuring roll and bearing arrangement.
? The surfaces closest to the load cell, and other surfaces that affect the fit must be machined
fl@t to within 0.05 mm.
? There must not be any shims immediately above or below the load cell, as this may
adversely affect the fl@tness
Instead, shims may be placed between the adapter plate and
the foundation or between the adapter plate and the bearing housing.
? The screws that secure the load cell must be tightened with a torque wrench.
? The bearing arrangement for the measuring roll must be designed to allow axial expansion of
the roll with changes in temperature.
? Any drive to the roll must be applied in such a way that interfering forces from the drive are
kept to a minimum.
? The measuring roll must be dynamically balanced.
? The mounting surfaces of the load cells must be on the same height and parallel with the
measuring roll.
? In a corrosive environment, galvanic corrosion may occur between the load cell,
galvanized screws and adapter plates. This makes it necessary to use stainless steel screws
and adapter plates of stainless steel or equivalent. See adapter plates in A Drawings.
3.2 Unpacking
When the equipment arrives, check against the delivery document. Inform ABB of any complaint,
so that errors can be corrected immediately and delays avoided.
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 TECTYL 511 (Valvoline) or FERRYL (104), for example.
? Load cells, adapter plates, bearing housings, etc.
? Screws as listed in Table 2. page 20 to secure the load cell, and other screws
for bearing housing, etc.
3.4 Adapter Plates
The adapter plates for all load cell types in the PFTL 101 family must be machined and have a
fl@tness 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
When installing PFTL 101AER and PFTL 101BER adapter plates of austenitic steel must be used,
preferably acid resistant or stainless steel.
