Pressure transducers DMU 01 Standard version

Pressure transducers DMU 01
Standard version
Flush mounted diaphragm
Application
For electronic pressure measurement in industrial applications
(such as hydraulic and pneumatic
applications as well as machine and
plant construction).
Description
The DMU 01 pressure transducers
use proven ceramic measurement
cell technology and feature calibrated, amplified sensor signals which
are available as standardised voltage or current outputs.
DMU 01 features:
• High temperature resistance
• No mechanical ageing
• No transmission liquid
Accuracy of measurement
Deviation characteristics according
to IEC 60770 - limit point setting
(non-linearity, hysteresis, repeatability): < ±0,5 % FSO
Measuring ranges
Relative pressure: -1/0 to 0/400 bar
Absolute pressure: 0/1 to 0/400 bar
Overpressure safety
< 250 bar min. 2 x FS
> 250 bar min. 1.5 x FS
(burst pressure min. 3 x FS)
