MM series
4 Regulation Use
Kobold level transducers are used for the continuous level indication and level
control of all kinds of liquids. The simple design with only one moving part (the
float) is suitable for applications that demand reliability. Kobold level transducers
allow the continuous level indication and level control of liquids unaffected by
electrical conductivity, temperature, pressure. The level transducer may only be
used in liquids that will assure free movement of the float. The following points
must be noted:
no large particles
density of the fluid must not be less than that specified for the float type
pressure and temperature to be held within the limits given in the technical
specifications
A variety of transducers in various designs, connecting configurations and
materials are available for the acquisition of the measuring values.
Attention! These units should not be installed in the vicinity of strong
magnetic fields, since this can impair their intended functionality.
