The TIO-3000 System was originally
designed
to perform precision summing
on 2, 3 , or 4 load
cell signals for
weighing applications.
Development
has progressed into accessory
modules
with considerable versatility for
user
defined configurations in a
compact economical
five (5) slot
system
with built-in meter and
channel
selector.

TMO-3 AMPLIFIER/CONDITIONER Description
The TMO-3 Module provides sensor excitation,
zero balance control, gain adjustment and calibration resistor, necessary
to condition one
(1) strain gage type sensor signal for display on built-in meter, off
board recording or processing. The nominal output range of the module
is 0 to ±10 VDC. The TMO-3 module derives its power from the TIO-3000
motherboard. On-board regulators supply amplifier bias and bridge excitation.
Each module contains a two-pole filter as the final element.
Options
1.
A 4 to 20 mA current loop output is available as Option "A".
2.
The standard 16 Hz filter was picked for meter stability.
The bandwidth of the TMO-3 can be much higher if desired.
DSP-3 WINDOW ALARM Description
The DSP-3 is designed as a watchdog module
to monitor critical sensor data from a TMO-3 or SUM-3 Module. The window
is normally associated
with signals such as: below norma (yellow), go range or acceptable
(green), and above acceptable (red). Front edge LED's provide this
status, as do output relays. The window is set by a high and low potentiometer,
with set values displayed on the TIO-3000 meter, usually in a engineering
unit like the sensor channel it is tracking. Output relays can be used
to drive larger external alarm devices or to switch off the process
or activity that is causing the unacceptable level.

PKD-3
PEAK HOLD MODULE Description
The PKD-3 Module provides very fast response
to variations in data level and captures the highest peak that occurs
in a given monitor window. Unlike microprocessor controlled meters
that covert in digital readings at three samples per second and then
save the highest reading, the PKD-3 tracks continually and holds in
analog form until reset. The module has polarity select and reset control
which can be operated from the front edge of the module or remotely
by switching TTL control lines to ground.
A typical application for the PKD-3 is with a TMO-3 and a torque transducer
and used with an automatic nut runner. When the runner stalls, peak
torque is saved. If backoff torque is needed for system evaluation,
the module can be rest to zero and the polarity changed, both by computer.

SUM-3
PRECISION SUMMING MODULE Description
The SUM-3 Module is designed for precise weighing application
by accepting the output signals from 2, 3 or 4 TMO-3 conditioning modules
and performing the algebraic sum of those signals. Unlike resistor
summers, the active element summing junction does not require sensor
signals of matching output. The TIO-3000 approach provides a cal resistor
to scale amplifiers (TMO-3s) to engineering units. With data now standard
during setup, precision summing is accomplished.
Advantages
1.
Load cells are less expensive if calibrated, not standardized.
2.
A damaged sensor can be replaced and the system rescaled to
the new sensorical resistor.
3.
Load cells of two different capacities can be summed.
4.
Load cells may be dispersed at uneven locations to weigh an
odd shaped tank or structure.
Options
A 4 to 20 mA current loop output
is available as Option "A".
