C3267 Tension Transducer Amplifier Module
Description:
This load cell amplifier module is designed to interface and provide
signal conditioning for either one or
two semiconductor strain or foil type
load cell transducers, wired in a full
bridge configuration. The amplifier is
designed to interface with the
controls used to monitor and control
web tension in the continuous
processing of paper, fabric, film, foil
and cable.
Designed to operate in demanding
industrial environments, the module
features a highly stable instrument
amplifier and a regulated power
supply to limit the output signal variation to less than .2% as the input power supply and
operating temperature are varied over the specified range. Adjustable damping provides
high immunity to both conducted and radiated electrical noise.
The tension amplifier module provides a complete load cell signal conditioning system on
a single compact circuit board assembly. A regulated five volt dc power supply is included
for the load cell excitation. In addition, an unregulated dc power source is included to drive
a digital voltmeter. The amplifier output full scale voltage signal value is selectable. All
models provide a two volt range that is suitable for driving a digital voltmeter. The second
range output depends on the model selected and will be either five or ten volts. This signal
can be used as a control signal or for indication with an analog meter. The amplified load
cell output from the instrument amplifier is available on the terminal block and may be
used to drive additional amplifiers, via the expansion input on applications where more
than one indicator or where both indication and control signals are required
Models operate from either a 115 or 230 volt ac power line. Simple setup and calibration
is provided by the adjustments for the load cell excitation voltage, damping amount, signal
zero and span. All external connections are made to clearly marked removable terminal
blocks. The board can be mounted in the user's control enclosure on standoffs or located
in plastic mounting track.
Applications:
To power and condition the output from strain gage load cells. The output signal is used to
control or display the process tension.
