Pressure sensors from Danfoss Industrial Automation help Danfoss Semco control water level in vital firefighting systems delivered to customers around the world. The innovative use of MBS 9200 provides substantial savings in assembly costs.
The challenge: Achieve precise and reliable level measurement at minimum cost
Every year, Danfoss Semco installs hundreds of firefighting systems at hospitals, hotels, metros, museums, data centers and marine vessels all over the world.
These systems can be a question of life and death and priceless values may be at stake. Naturally, safety and reliability take precedence in design and delivery of the vital systems.
The water mist firefighting system supplied by Danfoss Semco relies on access to water. Therefore, the system is always equipped with a water tank to ensure that sufficient water is present at all times. In the event of fire, it is important that the water tank is full and that is why the water level needs to be constantly monitored in order to detect potential loss of water, for instance due to leakages.
A close collaboration between Danfoss Semco and sensor specialists at Danfoss Industrial Automation led to the new solution for measurement of water level by means of water column pressure. The solution relies on Danfoss MBS 9200 sensors for land-based firefighting systems and MBS 9300 sensors for marine systems. The sensors are now used in the majority of water mist solutions delivered by Danfoss Semco.
