Ceramic pressure transducer HydroFox® DMU 09

4-20 mA2-wirefor liquids

Chemical-resistant plastic version Robust ceramic diaphragm without transmission liquid Highly resistant FEP cable Special calibration for all standard pressure units possible Application For electronic, continuous level measurement in extremely corrosive liquids, e.g. chemicals or waste water from landfill sites. Description Pressure transducers HydroFox® convert physical pressure into an electrical signal proportional to the pressure. HydroFox® DMU 09 uses a capacitance ceramic measuring cell.
