Level monitoring
Overfill protection & low level guard
MAFA paddle guards & capacitive sensors with a common connection point for level guards mounted in, for example, a silo.
The junction boxes are equipped with terminals for connection of supply voltage, level sensors and external warning lights for max and min level.
It is also possible to get 24VDC to connect, for example, a weighing instrument. Available in two versions, for use with one or two sensors.
Silo weighing
With MAFA Silo weighing, you get control of delivered material and consumption in the best and most accurate way.
A set for silo weighing consists of load cells incl. pressure plate, junction box, attachment for silo foot and instrument for displaying the contents of the silo in kg.
Guided microwave Level sensor
ATEX-classified according to EEx 1/2 d
MAFA Guided microwave Level sensor is excellent for solid materials such as feed and wood pellets and works according to the TDR (Time Domain Reflectometry) principle, which is well known from measuring cable interruptions.
The distance to the material is directly proportional to the pulse time. The TDR technology is independent of the material and the space above. The measured signal is converted to a 4 – 20 mA current and a HART signal for further processing. Micropulses are sent along a line at the speed of light. When the pulse reaches the material surface, it is reflected back to the level transmitter.
MAFA Connect
En komplett molnbaserad lösning för nivåkontroll i silo.
MAFA Connect sköter bevakningen av materialnivån i silon, och presenterar på ett enkelt sätt mätvädena i mobiltelefon eller dator.
MAFA Connect kan även anslutas till din leverantör av bulkvaran, det ger både dig och din leverantör ökad trygghet och fördelarna av välplanerade leveranser.
Agitator
MAFA Agitator is designed to facilitate emptying in silos with a UNIK auger box, when storing sluggish and aggregating materials. Worm gear motor-driven shaft with agitator vanes, mounted in UNIK auger box, can also for retrofitted.
Silo filler
The silo filler is used when you want to fill material from small or Big bags into a silo. The system consists of a mineral dispenser connected to transport auger. In the Mineral Dispenser, a grille is mounted. It is used partly as protection against the rotating transport auger and partly it can be used to put sacks on when emptying (maximum weight 1000 kg).
The transport auger is mounted against the mineral dispenser and vertically up along the silo. From the outlet, material is released through the silo roof.
Ladder and roof platform
MAFA silo can be equipped with a roof platform and side ladder for easy access to e.g. self-cleaning filters or shutters. Gangways between silos are also available as an option.
Electrical controls
MAFA manufactures and develops its own electrical controls for all types of installations. MAFA can supply controls for everything from a simple transport auger from silo, to control systems for entire feed preparations or industrial processes.
