ABB Vertical Measurement PFCL 201 Repeatability error

Load cells are machined from a single piece of stainless steel. 

The load cell is machined directly onto the steel piece and is positioned so that

it is sensitive to forces in the direction of measurement and insensitive to forces in other directions.

The load cell is mounted to the base with four screws and the bearing

housing is mounted to the top of the load cell with four screws.

Each load cell is calibrated and temperature compensated.

The load cells PFCL 201C/201CE/201CD are available in four measuring

ranges and all models have the same external dimensions.

The load cell PFCL 201C is equipped with connectors for plugging and unplugging the connection cable.

The load cell PFCL 201CE is equipped with a connection cable with protective hose.

Load cell PFCL 201CD with acid-proof cable gland and PTFE insulated connecting cable.

Repeatability error

Repeatability error is the maximum deviation between repeated readings under identical conditions.

It is expressed as a percentage of the sensitivity at rated load.

Compensation Temperature Range

The temperature drift of a load cell is compensated for over a specific temperature range.

This is the temperature range over which the load cell maintains the specified

allowable temperature drift (i.e. zero drift and sensitivity drift).

Operating Temperature Range

The operating temperature range is the temperature range over which the load

cell can operate within the specified accuracy. The load cell's maximum allowable temperature drift

(i.e. zero drift and sensitivity drift) does not necessarily remain constant throughout the operating temperature range.

Storage Temperature Range

The storage temperature range is the temperature range over which the load cell can be stored.

Zero Drift with Temperature

Zero drift is the variation of the sensitivity-related signal with temperature when the load cell is at zero load.

Sensitivity Drift with Temperature

Sensitivity drift is the variation of the signal with temperature, related to sensitivity, excluding zero drift, at rated load.
