Our state of the art facility. [Get Map]
Transducer Techniques Inc., established in 1979, designs
and manufactures a complete line of load cells, torque sensors, special
purpose transducers and related instrumentation. Transducer Techniques
load cells are uniquely designed for weighing and force measurement in
such diversified applications as process control, factory automation plus
hundreds of other services in every field of science and industry. All
transducer sensing elements incorporate bonded foil strain gages wired
in a full wheatstone bridge configuration.
TECHNOLOGY
Load cells are electro-mechanical transducers that translate force or
weight into voltage. This change in voltage produces, in the read-out
instrumentation, a repeatable deflection or indication that can be calibrated
directly in terms of the load applied to the cell.
CONSTRUCTION
Construction of the load cell utilizes all the advantages of bonded foil
strain gages . Sealed within the load cell are sets of matched strain
gages bonded to a high strength element, machined to close tolerances.
The strain gages are electrically connected to form a balanced Wheatstone
bridge and additional compensation resistors are added to the circuit
for maintaining the accuracy of the bridge over a wide temperature range.
OPERATION
The principle of operation depends upon the deflection of the strain gage
filament, creating a change in its resistance, thereby unbalancing the
bridge circuit. As a result, for a given input voltage, the output voltage
of the bridge varies proportionally with the load and the change can be
read on appropriate instrumentation.
QUALITY
When completed, each load cell is individually tested and calibrated.
Each cell must meet or exceed rigid electrical and mechanical performance
tests before it is released for service. Also, every cell is proof tested
to its full rated capacity, and in most instances, to over its rated capacity.
ATTRIBUTES
An important asset of our load cells is their extremely small deflection.
The maximum deflection of standard cells does not exceed .012" at
full load. This plus the fact that these load cells contain no moving
parts, opens unlimited application fields. The inherent compactness of
the cells minimizes installation problems.
The frequency response characteristics of our load cells are exceptionally
good. The relatively low mass, and the small deflection under load, result
in a high frequency response which emphasizes use of the cells in many
services where other transducers cannot perform.
Only strain gages of the highest quality are installed and configured
by technicians who have undergone our extensive training program targeting
craftsmanship and attention to detail. To the end user, this means a quality
product. All Load Cells / Force Sensors, and Torque Sensors are supplied
with a Calibration Certificate traceable to NIST.
