GENERAL
SandSET-1000 12 VDC is an alarm device to indicate the accumulation
of sludge or sand layer on the bottom of a well or tank. Typical
applications are sand and oil separators as well as settling tanks of
wastewater treatment plants and other wells or basins. Depending on
the order, the delivery consists of SandSET-1000 12 VDC control unit,
SET/S2 sensor, junction box and installation supplies.
Figure 1. Sand separator alarm application
SET/S2 sensor is installed in the separator or tank and it gives an alarm
when the sludge reaches the sensor. The sensor is normally immersed
in water.
The principle of measurement is ultrasonic. When sludge, sand or other
solid particles accumulate between the two sensor heads, the signal
strength weakens, causing an alarm.
SET/S2 sensor can be installed in a zone 0, 1 or 2 potentially explosive
atmosphere but the control unit must be mounted in a safe area.
The LED indicators, push buttons and interfaces of the SandSET-1000
12 VDC control unit are described in figure 2.
