Pressure transducers DMU 03

Pressure transducers DMU 03 Industrial version

manufactured goods

Measuring range	0/25 bar
Connection	G½B
Connection	EN 837-1/7.3
Electrical connection	Connector and junction box as per ISO 4400 (DIN 43650-A)
Part no.	31155

for low pressure ranges
Versions for relative pressure and absolute pressure
excellent long-term stability
Ex version (optional)
Option SIL 2

For electronic pressure measurement in mechanical and plant engineering as well as process engineering applications. With flush diaphragm, the pressure transducers are also suitable for use with viscous, highly viscous media.

Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 03 is equipped with an oil-filled piezo-resistive silicon measuring cell. DMU 03 has safety integrity level SIL 2 (IEC 61508/61511).
