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.Accuracy and Accuracy Class
Accuracy class is defined as the maximum deviation, and is expressed as a percentage of the sensitivity at nominal load. This includes linearity deviation, hysteresis and repeatability error.
Linearity Deviation
Linearity deviation is the maximum deviation from a straight line drawn between the output values
at zero load and nominal load. Linearity deviation is related to the sensitivity. Hysteresis
Hysteresis is the maximum difference in the output signal at the same load during a cycle from zero
load to nominal load and back to zero load, related to the sensitivity at nominal load. The hysteresis
of a Pressductor transducer is proportional to the load cycle. Repeatability error
Repeatability error is defined as the maximum deviation between repeated readings under identical
conditions. It is expressed as a percentage of the sensitivity at nominal load.
Compensated temperature range
The temperature drifts of the load cell have been compensated for in certain temperature
ranges. That is the temperature range within which the specified permitted temperature drifts (i.e.
zero point and sensitivity drifts) of the load cell are maintained.
