Elettrosonda DB
'Advanced and Multifunctional' LEVEL CONTROL UNIT
FOR CONDUCTIVE LIQUIDS.(DIN RAIL MOUNTING -4 DIN, 72MM-)
The ‘Elettrosonda DB’ is a multi-relay control unit designed to manage the levels of conductive liquids within preset parameters, activating/deactivating pumps or diverting valves and protecting submersible pumps from running dry. The system utilizes low-voltage electrodes, known as “probes,” powered at 24V AC, to detect changes in the liquid level. When the probes come into contact with the conductive liquid, the current passes through the liquid, activating the relay integrated into the control unit.
DB offers flexibility with its 3 relays (alarm, output 1, and 2) and 5 inputs (low alarm, high alarm, on/off control, and differential). Here are some of its functions:
- ON-OFF at a single point: Activates the relay when the probe reaches the desired level.
- Differential: Maintains the level between the LOW and HIGH probes.
- Level alarms: High and/or low level alarms.
- Audible alert for internal high and/or low-level alarms.
- Output signal for external alarm activation (e.g., audible or visual signals), with the ability to enable or disable controls using DIP-SWITCHES.
This versatile device can replace 4 separate relays use to function in a same way. DB is available in various power voltages, such as 24/117/230Vac.
Designed for
Applications
DB is mainly applied in the following contexts:
- Tanks and containers (even under pressure): monitoring and managing the water level(s) in storage tanks.
- Basins: Monitoring the water level in basins or ponds.
- Wells: Monitoring and controlling the water level(s) in wells.
- Rainwater Accumulation: monitoring and controlling the water level(s) in rainwater accumulations.
Features
- Multifunctionality: ‘Elettrosonda DB’combines in a single device three level control functions: on-off, differential, and alarm. This makes it much more versatile than a standard relay for water level, which can only perform one of these functions.
- Compactness: ‘Elettrosonda DB’ occupies only 4 DIN modules, making it suitable for installation in tight spaces.
- Flexibility: ‘Elettrosonda DB’offers a range of configuration options, including the ability to enable or disable various functions via DIP-SWITCH switches. This makes it suitable for a wide range of applications.
- Protection of submersible pumps: ‘Elettrosonda DB’ has a dry run protection function for submersible pumps. This feature is especially important to ensure the longevity of the pumps.
