Current Source 1 Setup
The level sensor is connected to the ORB though Current Loop 1. For current loop setup, use the
External
tab on the
ORB webpage or Senquip Portal and select the Current Loop 1 peripheral.
1.
Give the current data a meaningful name;
in this case “Water Level”.
2.
Water level data is to be sent every time
the ORB wakes up and so the Interval is
set to 1.
3.
Use the Start Time setting to apply power
to the sensor a short time before the
measurement is taken. This allows the
sensor data to stabilise before a
measurement is taken. Make this value
as short as possible to save energy when
operating off solar or AA batteries.
4.
Hysteresis is applied when warnings and
alarms are enabled. Hysteresis prevents
multiple alerts when the measured value
is oscillating around an event level.
5.
In this application, we have an alarm set if
the water level goes below 1m or above
4m. Note that if you calibrate the sensor,
warning and alarm settings are in the
calibrated units.
6.
Calibration in meters has been applied in
this application. According to the water
level sensor, 4mA represents 1m and
20mA represents 5m.
7.
The calibrated unit in this example is
meters (m). Note that the ORBs
webserver and the Senquip Portal will always report measured values in the calibrated units; meters in this
case.
