Maximum Peak
Sets the maximum peak value allowed for the AC component of the signal provided
by the sensor. Applies only for dynamic sensors, when
Check AC/bias
is checked.
Min. bias
voltage
Sets the minimum value in volts allowed for the DC component of the signal provided
by the sensor. Applies only for dynamic sensors, when
Check AC/bias
is enabled.
Max. bias
voltage
Sets the maximum value in volts allowed for the DC component of the signal provided
by the sensor. Applies only for dynamic sensors, when
Check AC/bias
is enabled.
For static sensors, VIGILANT will calculate the corresponding measurement
using this formula:
𝑀𝑒𝑎𝑠𝑢𝑟𝑒𝑚𝑒𝑛𝑡 =
(𝐶ℎ𝑎𝑛𝑛𝑒𝑙 𝑟𝑒𝑎𝑑𝑖𝑛𝑔 − 𝑂𝑓𝑓𝑠𝑒𝑡)
𝑆𝑒𝑛𝑠𝑖𝑡𝑖𝑣𝑖𝑡𝑦
where Offset and Sensitivity are set on the corresponding properties.
For dynamic sensors, the Offset value is subtracted from the raw dynamic signal
before converting it to the corresponding units using the Sensitivity defined.

Inputs
This section defines the configuration of the inputs. By clicking on this option, the interface shows the
inputs list.
By clicking on one of the items of the list, the interface will show the configuration of the corresponding
input. Once configured, the added item defines the correlation between the sensor and the physical
input of the VIGILANT that must be used to connect the sensor.
Field
Description
Name
Shows the input channel to be configured.
Mode
Defines the type of input that will be used:
•
Dynamic:
used for voltage dynamic signals (vibration, ultrasound). Enables the
input to sample the signal at high frequency sampling rates.
•
Voltage:
used for voltage static signals. The input will sample the signal at low
sampling rates.
•
Pulse train
: sets the channel to read pulsed voltage signals. This type of input
mode allows the system to measure the frequency of the pulses in Hz. The trigger
level and hysteresis can be set up by the user.
