Strain Gauge Sensor Cable Coloration; Voltage Output Connection - Unipulse F350 Operation Manual

■Strain gauge sensor cable coloration

Cable colors of sensors may differ from one manufacturer to another (it may even differ from one
model to another for some products). Refer to the sensor manual (or data sheet) and check signal
names and colors in order to connect the cables correctly.
The excitation voltage of the F350 is 2.5V/10V. If the maximum excitation voltage of
the sensor is under 2.5V/10V, heating or damage may result.

■Voltage output connection

The voltage output terminals output analog voltage in proportion to each sensor signal input.
The voltage output is approximately 2V per sensor input of 1mV/V.
It is useful for observing or recording waveforms by connecting a recorder, etc.
・Example) Connection of output equivalent circuit and external instrument.
A/D
・ Since the output voltage is taken out in a step prior to A/D conversion of the sensor input signal, it
is not synchronized with indicated values processed digitally, such as Digital Zero and digital
filter. Output in synchronization with indicated values requires an optional D/A converter.
・Since the ±MONITOR terminals are not insulated from the internal circuit, use two-core shielded
twisted pair wires for connection with external equipment, and carry out with as short a wiring as
possible.
● Do not short-circuit. Doing so will cause a failure.
● Do not apply voltage externally. Doing so will cause breakage.
