Differential pressure transducer DeltaFox DMU 21 D

piezoresistive4-20 mA3-wire

LED display and open collector switching output Turn down up to a maximum of 1:10 through customer Min./Max. value storage Housing can be rotated by 330° and pressure connections by 300° Application For electronic differential pressure measurement which requires a local display in addition to the analogue output, for example for monitoring filters and fans. The differential pressure transducer can be used with all liquid and gaseous, corrosive media which a not highly viscous and which do not crystallize. Description The DeltaFox®DMU 21 D pressure transducers feature two oil-immersed piezo-resistive stainless steel measuring cells and a 4-digit, red LED display. When pressure is applied, the pressure difference between the positive pressure side and the negative pressure side is converted into a current signal which is proportional to the differential pressure. A menu and two keys allow for displaying the measured values and for configuring the individual parameters. Technical data Measuring accuracy Deviation from the characteristic curve according to IEC 60770 – limit point calibration (non-linearity, hysteresis, repeatability) Display 4-digit, red 7-segment, LED display, Character height 7 mm, Range -1,999/+9,999, Accuracy 0.1 % ± 1 digit, Digital damping 0.3/30 s (programmable), Display housing can be rotated by 330° Adjustment possibilities Turn down 1:10 Reference point for switching and analogue output selectable on + connection, - connection or differential pressure Measuring range See ordering table Application area The maximum pressure in the system (maximum static pressure, one end) must not exceed the full scale value (FS).
