Relative pressure transducer DMU 05 P

siliconpiezoresistive4-20 mA

Precision version with outstanding measurement performance For applications requiring superior measuring accuracy and long-term stability Options: ATEX version or RS 232 interface Application For electronic pressure measurement in applications requiring high measuring accuracy and long-term stability, such as process engineering, water treatment, laboratory applications as well as measurements of gas consumption and heat energy. Description Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 05 P is equipped with an oil-filled piezo-resistive silicon measuring cell. The intelligent DMU 05 P pressure transducers are equipped with digital amplifier electronics (microprocessor and 16 bit A/D converter). DMU 05 P actively compensates for sensor-specific deviations (non-linearity and temperature error), allowing for superior measuring characteristics. DMU 05 P can also be supplied with optional digital RS 485 Modbus RTU for setting offset, range and damping.
