Description
ALZ 3740 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 stainless steel housing make APZ 3740 a transmitter of choice for the viscous and abrasive media. For even better compatibility with aggressive media please refer to the similar model APZ 3742 with the plastic housing.
