Xforce load cell

5 N - 250 kN

Accuracy class

ISO 7500-1

Special feature

One load cell for two system configurations

Patented Xforce load cells - exclusively from ZwickRoell

Xforce load cells are ideal for tensile, compression and flexure tests and for cyclic tests with zero crossing. The highly accurate, patented Xforce load cells from ZwickRoell are used for all load frame series. We make no compromises when it comes to quality.

All Xforce load cells are highly insensitive to parasitic influences such as transverse forces, bending moments, torque and temperature variations.
Xforce load cells are very robust and can withstand loads up to 300% of nominal capacity without mechanical failure and up to 150% without zero-point shift.
These intelligent load cells have a unique electronic identification system stored on an internal EEPROM.
Xforce load cells fulfill all five criteria of the ISO 7500-1 accuracy classes over a very large measurement range.
Xforce load cells are based on a patented mechanical setup and are highly resistant to transverse forces.

Advantages and features of the Xforce load cell

The heart of the testing system

High-quality load cells are essential for achieving reliable, interpretable test results. To ensure optimal integration of this core element into the testing system, ZwickRoell has developed its own range of load cells: Xforce P (Precision), Xforce HP (High Precision), and Xforce K

The highly accurate Xforce P load cells are intended for use in tests which do not involve high transverse forces. This includes many tensile tests (though not on shear specimens, for example) as well as compression, flexure and component tests in which no high transverse forces, bending moments or torsional moments occur.
Xforce HP and Xforce K differ from Xforce P load cells primarily in their larger measurement range and greater resistance to parasitic influences such as bending moments, torsional moments, and temperature variations. They are ideally suited to all static tensile, compression and flexure tests and are naturally equally suitable for pulsating or cyclic tests with zero crossing.
Before dispatch each load cell is calibrated with the testing machine plus drive and the measurement and control electronics as a complete system. This is recorded in the supplied factory calibration certificate.

All components from a single source: ZwickRoell develops and produces all system components in-house: The testXpert III testing software, the testControl measurement and control electronics, Xforce load cells as well as all mechanical components.

Self-Identifying Sensor Plug

These intelligent load cells have a unique electronic identification system stored on an internal EEPROM.

The testXpert III testing software automatically identifies the sensor type and properties.
Force and travel limits are automatically imported.
Sensor overloads plus date are stored in the EEPROM.

Calibration and Accuracy to ISO 7500-1

ISO 7500 metallic materials—Verification of static uniaxial testing machines consists of two parts:

ISO 7500-1: Tension/compression testing machines—Verification and calibration of the force-measuring system
ISO 7500-2: Tension creep testing machines—Verification of the applied force

ISO 7500-1 contains general information on requirements for and on the verification and calibration of tensile, compression and flexure testing machines; spring testing machines and fatigue testing machines.

System calibration

Before dispatch each load cell is calibrated with the testing system plus drive and the measurement and control electronics as a complete system. This is recorded in the accompanying factory calibration certificate.

Large measurement range

The large measurement range frequently eliminates the need to purchase a second load cell, saving the costs of acquisition and annual calibration.
Even with high pre-loads due to heavy test fixtures or specimen grips, virtually the entire load-cell measurement-range remains available. The load cell can still be used to full nominal capacity with fixture weights amounting to 45 % of nominal force.

Outstanding linearity

Xforce HP and Xforce K load cells feature very high accuracy.
Used in conjunction with testControl II electronics, Xforce HP and Xforce K (from 200 N) load cells typically offer significantly better linearity (= relative display deviation) than required by ISO 7500.
The maximum display deviation is less than 1% of the measured value from as low as 0.1% of the load cell nominal capacity; from 0.4% of nominal capacity it is 0.25% of the measured value.

Overload protection, force limits and operating force

Xforce load cells are very robust and can withstand loads up to 300% of nominal capacity without mechanical failure and up to 150% without zero-point shift. This means that overload protection such as pre-loaded springs, mechanical stops or guiders to absorb transverse forces is generally unnecessary.
The crosshead travel range can be restricted via software and hardware limit stops, protecting load cells and text fixtures.
Force limits can be set in testXpert III to switch off the testing system automatically, protecting the load cell.

Simple mechanical plug-in system, including for two slots

Each load cell is equipped with a precision-fit mounting stud, allowing fast, play-free fitting of specimen grips and test fixtures, with optimum alignment to the test axis.
Reference positions (e.g. test-fixture separation) are set up just once by the operator and are stored in the test environment of the testXpert III testing software. This reference position is automatically and exactly re-attained after each fixture change. It doesn't get more convenient than that!
With Xforce K load cells a second mounting-stud can optionally be used, allowing use in two test areas.

Daily Check Device

The Daily Check Device is used for checking load cells up to 500 N. The device detects systematic errors in compression and tensile direction in the load cell.

Xforce Load Measuring System with Load Bypass Unit

During tests in the compression direction, Xforce HP load cells are safeguarded by mechanical overload protection and an integrated load bypass unit.

Technical overview of the Xforce load cell

If several load cells are to be used, or in the event of frequent load cell changes, we recommend the 'Connection via Mounting Stud' option.

Saves time and increases flexibility.
Avoids unnecessary strain on the load cell cable during screwing in and unscrewing.
The plug-in system delivers better alignment to the test axis than the usual threaded mounting.
Reference positions for different test arrangements are automatically re-attained (with a threaded mounting, reference positions change according to the number of turns screwed in).
