204 Delayed conductivity level controller for DIN rail
Thanks to its compatibility with DIN rails, the 204 series level regulator can be installed quickly and easily on electrical panels, optimising space and ensuring greater flexibility.
These regulators are used to maintain the level of liquid, powder or solid conductive products within pre-set levels. They can also be used to signal overflow, overempty or dry running alarms and at the same time protect pumps from continuous and frequent interventions.
Product Description
Electrically connected to one of the 390/395/396/600/700/710 series probes, it is used to maintain the level of conductive liquids between 2 fixed levels; particularly used to read the water level in boilers between 2 fixed levels; when the water level drops below the set level, the pump starts, when the level rises above the set level, the pump stops; or it is used for maximum or minimum level alarms, acting on a pump or a solenoid valve.
A green LED indicates power and a red LED indicates when the level has been reached. They are divided into ranges in order to control products with conductivity ranging from 0.5 µS to 10000 µS.
An internal trimmer called “sensitivity” allows you to adjust the intervention threshold based on the conductivity of the water.
The 204 series regulators allow direct mounting on DIN rail, reducing the height, and can also be placed next to standard switches.
Thanks to an internal delayer, they ignore false level signals caused by waves or ripples, there are two possible solutions: – when the water reaches the maximum level – when the water drops below the minimum level.
Advantages:
Versatility: Suitable for a wide range of conductive liquids, from the purest to the most contaminated.
Precision: The high-sensitivity detection system guarantees accurate measurement even in difficult conditions.
Reliability: Built with high-quality materials and designed to withstand harsh industrial environments.
Ease of use: Simple to install on DIN rail and configure, thanks to the internal trimmer that allows you to adjust the sensitivity based on the characteristics of the liquid. The delay circuit, also adjustable and settable to excitation or de-excitation, eliminates false alarms and optimizes performance.
Typical applications:
Boilers: Maintaining the water level between two preset levels, preventing overheating and ensuring optimal operation.
Tanks: Monitoring the level of conductive liquids, avoiding excessive filling or unwanted voids.
Treatment plants: Controlling the level of sludge and aqueous solutions, optimising production processes.
The delay circuit, adjustable via an internal trimmer, allows you to:
Adapting the regulator to different working conditions: presence of turbulence, etc.
Eliminating false alarms: avoiding unwanted activations caused by waves or ripples on the surface of the liquid.
Optimising performance: ensuring precise and reliable measurement in any condition.
