INPUT SIGNALS READING
LogBox BLE
allows
users to choose, along with channels to be registered and sensor types, some configurations that provides flexibility to various
applications, allowing users to consider the energy resource
s (battery life) and data storage (length of log memory). Thus, it is possible to configure
the device with the following parameters:
●
Log Interval:
Frequency, in seconds, with which an acquisition must be made and logged in the memory. Low frequency increases battery
consumption and
fills memory faster.
○
Mini
mum Interval:
■ 1 second (If no channel is configured to operate on average);
■ 10 seconds (If a channel is configured to operate on average).
○
Maxi
mum Interval:
24 hours.
●
Display Update Interval:
Frequency, in seconds, with which an acquisition must be made and updated on the display. It allows you to save
memory by configuring it to a larger range of logs with a f
aster Display update rate. Low interval increases battery consumption. This range can
be disabled by configuring it to ‘0’. Thus, the display update will take place in the log interval.
○
Mini
mum Interval:
1 second;
○
Maxi
mum Interval:
1 hour.
When configuring a display update interval, it should be les
s than the log interval. Otherwise, it will be ignored, and the display will be updated in
the Log Interval.
The display update in
terval only updates analog channels that are not configured to operate on average. Thus, the digital channel that is configured
to operate in pulse c
ounting mode and the analog channels that are configured to operate on average will only have their information updated at
each log interval.
If
the digital channel is operating in the "Event Log" mode, it updates its respective information on the display to each event.

ANALOG INPUTS
LogBox BLE
has thr
ee channels for reading analog signals. The types of signals and sensors accepted are:
●
Te
mperature Sensors:
○ Thermoresistance Pt100;
○ Thermocouples J, K, T, N, E, R, S and B;
○ Internal Temperature Sensor.
●
Linear Sensors:
○ 0 to 50 mV;
○ 0 to 5 V;
○ 0 to 10 V;
○ 0 to 20 mA;
○ 4 to 20 mA.
●
Internal Diagnostic Sensors:
○ Battery Voltage;
○ External Power Supply Voltage.
Each of these types of sensors has specific operation
configurations and characteristics. Below are described these configurations and
characteristics:
●
Te
mperature Sensors:
○ Temperature Sensors inform the measured sensor temperature within the possible measuring range of each sensor.
○ The maximum resolution for the Temperature Sensors is 0.1 °C;
○ You can configure them to be displayed with one or no decimal places;
○ You can configure them to be displayed in units of measure °C or °F.
●
Linear Sensors:
○ The Linear Sensors inform some magnitude, in the range required by the user (User Range), as configured in the "Lower Limit", "Upper
Limit", and "Nu
mber of Decimal Places" parameters.
■
Nu
mber of Decimal Places:
you can choose to use 0, 1, or 2 decimal places;
■
Lo
wer Limit:
Value configured by the user to represent the minimum value of the chosen sensor;
● Minimum -19999 to 0 decimal places;
● Minimum -1999.9 to 1 decimal place;
● Minimum -199.99 to 2 decimal places.
■
Upper Li
mit:
Value configured by the user to repr
esent the maximum value of the chosen sensor;
● Maximum 19999 to 0 decimal places;
● Maximum 1999.9 to 1 decimal place;
● Maximum 199.99 to 2 decimal places.
○ You can configure them to be displayed in units of measurement °C, °F or customized (8 characters - will not show on the display);
○ The maximum resolution for Linear Sensors is a ratio between the User Range and the maximum resolution of the chosen sensor.
