AUTOMATED FORCE CALIBRATION SYSTEMS
Tovey Automated Systems.
Tovey Engineering is the industry leader in force transfer standard calibration systems. TEI developed the first automatedsystems on the market and has the largest installed base in
the US. Over the years, we have continued to engineer andrefine our systems for maximum performance and custom-55K lbf Systemer ease-of-use. Tovey systems are designed specifically for
metrology grade calibration, rather than being modified test
systems, and achieve the lowest measurement uncertainties
of any competitive systems. All key components of our systems are manufactured by the company in-house to meetexacting standards for metrology use. Reliability is excellent,
and the alignment is second to none. TEI automated systems
closely approximate results from deadweight calibrators.

PORTABLE CALIBRATION SYSTEMS
Tovey provides self-contained mobile platforms for remote system verification
with reference standard load cells and/or dead weights. These systems provide
everything an operator needs to perform a verification at a testing machine or ina stress lab test cell. Portable systems include several reference load cells, cables,
fixtures, an instrument, a load cell simulator and a laptop computer. Systems arecalibrated at the factory as an integrated unit. Software is provided to acquire
data and verify that the system under test produces measured forces within a
specified tolerance band. The calibration system also provides a measurementof non-repeatability. Tovey’s portable systems are often used to perform verifications consistent with ASTM E4 or other requirements. Push cart or carry caseformats are available.
System Accessories Cart

CALIBRATION ACCESSORIES• Adapters and Loading Fixtures. Tovey manufactures a wide variety of standard thread adapters and custom made fixtures to satisfy the requirements ofour customers. All parts are heat treated to provide high strength and wear
resistant surfaces. All parts are engineered to provide excellent alignment.
Premium materials are utilized in manufacture. Rod end bearings, clevises,
compression load plates, and special adaptors for many applications are also
provided by Tovey.
• Rotation washers are designed to provide for rotation of the unit under test for
ASTM E-74 /ISO 376 calibrations. These washers allow precise rotation of the unit
under test and permit quick setups for significant time savings.
System Accessories

SYSTEM ALIGNMENT VERIFICATION• Alignment dynamometers. Tovey alignment dynamometers permit highaccuracy misalignment measurement. Dynamometers have three or four
strain gages equally spaced around the circumference of the part at either twoor three axial positions. When installed in a load frame and a force is applied,
readings from the individual strain gages can be used as a measure of misalignment, providing a quantitative measure of that misalignment.
• Multi-axis load cells measure force and moment in orthogonal planes. The
moment readings from these load cells provide information that permits alignment adjustments to be made and also quantifies the amount of moment that
may be applied along with the axial force. Tovey’s standard and special multiaxis load cells are among the world’s most accurate.
Dynamometers

SHUNT CALIBRATION PRODUCTS
Shunt calibration is often used to provide a means of setting up an instrument in the field. Tovey offers two options tomeet this need. An automated shunt cal module features four separate shunt calibration values. Any number of these
resistor values can be switched into the circuit in sequence or used individually. This instrument is capable of performing shunt calibration on single, double, or triple bridge load cells simultaneously and in a fully automated manner. A lower cost option consists of shunt calibration adapters that attach directly to the connector of the unit under test.
