  • for pressure ranges up to 1,000 bar
  • suitable for high overloads
  • insensitive to pressure peaks
  • Ex version (optional)

For electronic pressure measurement in machines and systems with technical gases (e.g. oxygen, oil-free, grease-free) and for use in hydrogen applications.

Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 30 is equipped with a welded stainless steel measuring cell.
