4-20 mA pressure transducer DMU 30

2-wireM12 connector32VDC

Suitable for high overloads Insensitive to pressure peaks Ex version (optional) Application For electronic pressure measurement in machines and systems with technical gases (e.g. oxygen, oil-free, grease-free) and for use in hydrogen applications. Description Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 30 is equipped with a welded stainless steel measuring cell.
