Description

Overview

Essential details：PFCL201C 50kN 3BSE006699D0005 Pressductor PillowBlock Load Cells

The load cell is machined from a single piece of stainless steel. The sensors are machined directlyin the piece of steel and are positioned so that they are sensitive to force in the direction of meas-urement and insensitive in other directions.
The load cell is mounted on a base with four screws, and the bearing housing is mounted on topof the load cell with four screws.
Every load cell comes calibrated and temperature compensated.
The load cells PFCL 201C/201CE/201CD are available in four measurement ranges, all variantshave the same external dimensions.
The load cell PFCL 201C is equipped with a connector for the pluggable connection cable.The load cell PFCL 201CE has a fixed connection cable with protective hose.The load cell PFCL 201CD is provided with an acid-proof cable aland with a fixed PTFE- insulatedconnection cable.

Repeatablity eror
Repeatability error is defined as the maximum deviation between repeated readings under identicalconditions. lt 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 temperatureranges. 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.
Working temperature range
Working temperature range is the temperature range within which the load cell can operate withina specified accuracy. The maximum permitted temperature drifts (i.e. zero point and sensitivitydrifits) of the load cell are not necessarly maintained in the whole working temperature range.
Storage temperature range
Storage temperature range is the temperature range within which the load cell can be stored.
Zero point drft with temperature
Zero point drift is defined as the signal change with temperature, related to the sensitivity, whenthere is zero load on the load cell.

The measuring principle of the sensor is based on the Pressductors technology and the fact thatthe permeability of a magnetic material changes under mechanical stress.
The sensor is a membrane machined in the load cel. Primary and secondary windings are woundthrough four holes in the load cell so that they cross at right angles.
The primary winding is supplied with an alternating current which creates a magnetic field aroundthe primary winding. Since the two windings are at right angles to each other, there will be no mag.netic field around the secondary winding, as long as there is no load on the sensor.
When the sensor is subjected to a mechanical force in the direction of measurement, the propaga.tion of the magnetic field changes so that it surrounds the secondary winding, inducing an alternating voltage in that winding.
The control unit converts this alternating voltage into a DC voltage proportional to the appliedforce. lf the measurement force changes direction, the sensor signal changes also polarity.

When choosing a mounting arrangement it is important to remember to position the load cell in adirection that gives sufficient measuring force (F,) to achieve the highest possible accuracy.The load cell has no particular correct orientation; it is positioned in the orientation best suited forthe application, bearing in mind the positions of the screw holes. The load cell can also be installedwith the roll suspended under the load cel.
The load cell has the same sensitivity in both tension and compression, so the load cell can beinstalled in the easiest manner.
Typical mounting arrangements are horizontal and inclined mounting.
