The
DFGS force gauge offer the highest level of sophistication, accuracy
and operational features within a single product. Its rapid
internal sampling rate, set point capability and other programmable
test parameters are well suited for demanding R&D requirements
as well as precise production floor applications.
The standard bi-directional RS232
interface permits on demand data transmission as well as peripheral
control of all gauge keypad functions. The highly accurate
analog output voltage provides for precise graphing of the force
curve. When integrated with a Chatillon TCD-200
digitally controlled test stand, the DFGS becomes the heart
of an extremely versatile tester system.
Operation Features:
- Internal digital sampling rate
of 5000 samples per second
- Programmable high and low force
set points with audible indicator and RS232 output signal for
stopping motor drive on Chatillon TCD-200 digital test stands or cycling the stand between the
set points. Operator may configure audible indicator and/or
RS232 output signal inactive while maintaining set point values
in memory.
- Peak function automatically captures
and stores highest instantaneous reading within each test.
The peak function may be engaged prior to testing to freeze the
display at the highest reading. It may also be engaged after
the test to display the peak value stored. The "zero" and
Star keys clear peak memory.
- Tension/compression modes are
indicated by "T" for tension or "C" for compression
upon force application. In the digital output, tension values
are identified with a minus sign
- Contact closure, force capture
function can capture the instantaneous electric contact force
within keypads, buttons, switches, etc. In this application,
the test contacts are electrically connected to the DFGS via two
pins on the output connector. Upon contact closure, the
DFGS is electrically prompted to freeze the digital display as
well as the analog output level.
- Selectable units of measurement:
lb, kg or N (250 gram gauge reads in units of oz, g or N)
- Push button calibration in any
selected units
- Rechargeable battery or AC operation
allows 8 hour continuous battery operation with 12-14 hour charge.
Low battery indicator on display. Continuous AC operation via
charger/AC adaptor
- Auto shut-off function preserves
battery life. DFGS shuts off if idle for 10 minutes. Operator
may deactivate this feature if undesirable.
- Available for 110 VAC or 220 VAC
Output/Interface
Features:
- Bi-directional RS232 interface
for data transmission as well as peripheral control of all gauge
keypad functions. Digital data transmission up to 100 data
points per second may be accomplished via the interface. Data
transmission parameters are user-selectable. (Baud rates
from 300 to 19,200). When interfaced with a Chatillon TCD-200 digital test stand, the DFGS may be programmed to transmit
an RS232 signal upon reaching a force set point in order to stop
the test stand motor or cycle the stand between force set points.
- Mitutoyo output (modified BCD)
for use with Mitutoyo brand processors
- Precise Analog Output: 0 to ±2.0
VDC full scale with accuracy of ±0.18 volts. "Zero" key
will zero analog output as well as display for preload applications
Physical Design
Features:
- Die cast metal reversible housing.
Split housing design permits upright display whether gauge is
hand held or test stand mounted.
- Easy to read 1/2" high LCD
display with 4-1/2 digits for forced value. Smaller characters
within the display indicate units of measurement, test mode,
set
point and low battery
- 9 key membrane keypad
- 2 separate rear mounting hole
patterns (#10-32 thread)
- #10-32 x 3/16 long thread on
load cell shaft
- Output connector: 12 pin "Hirose" design
