Pressure Transducer Continuous Level Measurement in Highly Corrosive Media
The Afriso Hydrofox DMU 09 pressure transducer is a screw-in probe for electronic, continuous level measurement in highly corrosive media such as chemicals or landfill waste water.
The probe is inserted into the medium from the top via a cable gland (PG 11). It is supplied via a 5 m FEP cable with integrated breather tube for reference to the ambient atmospheric pressure. A capacitance measuring cell integrated into a polypropylene housing which is resistant to chemicals serves as the basis of the pressure sensor. The sensor element does not require transmission liquid in the measuring cell. Therefore, the medium cannot be polluted in the case of damage.
The probe DMU 09 converts relative pressure in the pressure ranges 0/40 mbar to 0/10 bar into a proportional 4-20 mA signal at high accuracy (< ± 0.35 % FSO). Special calibration for all standard pressure units is possible.
The probe is short circuit proof and protected against reverse polarity, it is supplied with DC 9-32 V and suitable for ambient temperatures and temperatures of the medium from -25 °C to 70 °C. DMU 09 can also be made to customer specifications with a PVDF housing, a protective pipe for the cable or FFMK seals. A comprehensive range of optional accessories such as screw connector kits, junction boxes and anchor clamps allows for the implementation of numerous applications.
