描述
2.1概述
PFTL 101系列中的称重传感器有六个不同的测量范围,从0.5到20
kN和两种不同尺寸(见2.2技术数据)。每个称重传感器单独校准,并且
温度补偿。
称重传感器通常用六个螺钉安装并固定在底座和轴承箱上,四个
在称重传感器的一侧,两个在相对侧。
对于PFTL 101型的所有称重传感器,称重传感器室由一块钢加工而成。
然后将传感器焊接到称重传感器室中,并进行定向,使其对
测量方向,对其他方向不敏感。

oad cells are installed under the roll bearings, where they measure forces parallel to the
mounting surface.
The reactive force from the web/strip, which is proportional to the web/strip tension, is transferred
to the load cells via the roll and the bearings
The load cells are connected to the control unit via a junction box. The control unit converts the
load cell signals to DC voltages that are proportional to the reaction force. Depending on which
control unit is chosen, it is possible to have the analog signals for the two individual load cells (A
and B), the sum of the load cell signals (A+B), and/or the difference between the load cell signals
(A-B).

1.4.3 Principle of Measurement
The load cell only measures force in the direction FR. The measurement force may be positive or
negative. The load cell is normally installed under the roll bearings. When there is a web/strip in
tension over the roll, the tension (T) gives rise to two force components, one in the direction of
measurement of the load cell (FR) and one at right angles (FV
).
The measuring force depends on the relationship between the tension (T) and the wrap angle
formed by the web/strip around the measuring roll.

Description
2.1 General
The load cells in the PFTL 101 family are available in six different measuring ranges from 0.5 to 20
kN and two different sizes (see 2.2 Technical Data). Each load cell is individually calibrated and
temperature compensated.
The load cells are usually mounted and fixed to a base and a bearing housing with six screws, four
on one side of the load cells and two on the opposite side.
For all load cells of type PFTL 101 the load cell house is machined from a single block of steel.
A sensor is then welded into the load cell house and oriented so that it is sensitive to force in the
direction of measurement and insensitive in other directions.
The load cell types PFTL 101A, PFTL 101AE, PFTL 101B and PFTL 101BE are made of stainless
steel.
PFTL 101A and PFTL 101B are equipped with a connector for the pluggable connection cable.
PFTL 101AE and PFTL 101BE are equipped with a fixed connection cable.
Load cell types PFTL 101AER and PFTL 101BER are specially designed for installation in corrosive
environment. They are made of acid resistant stainless steel and they also have a fixed connection
cable.
Dimensions for all load cell types are given in A Drawings.
