ALZ 3742 is based on a high precision capacitive ceramic oil free sensor with ranges starting at 40 mbar for measuring liquid levels as low as 40 cm. High overload capacity of the sensor, flush ceramic diaphragm and plastic housing make APZ 3742 a great choice for the agressive(*) and viscous media . Similar model APZ 3740 in stainless steel housing is available for abrasive media applications.
