Pressure transducers HydroFox® DMU 09 | 31581

Pressure transducers HydroFox® DMU 09 level probe - for chemical applications

manufactured goods

Measuring range0/4 bar
Part no.31581

  • chemical-resistant plastic version
  • robust ceramic diaphragm without transmission liquid
  • highly resistant FEP cable
  • special calibration for all standard pressure units possible

For electronic, continuous level measurement in extremely corrosive liquids, e.g. chemicals or waste water from landfill sites.

Pressure transducers HydroFox® convert physical pressure into an electrical signal proportional to the pressure. HydroFox® DMU 09 uses a capacitance ceramic measuring cell.
