32.010/1 SDU: Fine-differential-pressure transducer How energy efficiency is improved Enables the accurate recording of duct pressures for the optimisation of energy consumption in ventila-tion systems. Areas of application Measurement of the smallest air currents and pressure differentials in air-conditioning and environ-mental applications, as well as in laboratories and clean room areas. Features „h Static membrane pressure transmitter „h Capacitive acquisition of data „h Accurate recording of differential pressures up to 10 mbar (1000 Pa) „h Adjustable measuring spans for optimal adaptation of measuring range to the application Y03197PD „h Automatic current/voltage switching Technical description „h Power supply 24 V~ „h Four measuring ranges: „h 0 to 100 Pa „h 0 to 200 Pa „h 0 to 400 Pa „h 0 to 1000 Pa „h Linearity 2% in relation to output signal 10 V- (20 mA) Output signal00Press. differenz ƒ´p Measuring span100 %B01115 span = 50 %span = 100 % Type Measuring range ƒ´p 1) Voltage Weight Pa mbar kg SDU 101 F001 0...100 0...1 24 V~ 0.8 SDU 101 F002 0...200 0...2 24 V~ 0.8 SDU 101 F003 0...400 0...4 24 V~ 0.8 SDU 101 F004 0...1000 0...10 24 V~ 0.8 Supply pressure 24 V~ +15/-20%, 50...60 Hz Permissible pressure Power consumption 2 VA Usable range pstat „b 3 kPa Low-pressure connections „b 5 kPa Setting range Permissible amb. temp. 0...40 °C measuring span 50...100% ƒ´p Permissible amb. humidity < 90% rh Type of protection IP 44 (EN 60529) Outputs Actual-value signal 2) 0(2)...10 V, Load > 500 ƒÇ Wiring diagram A01117 Linearity 2% of 10 V Dimension drawing M01104 Fitting instructions MV 505119 Accessories 0010240 300 Connecting kit, 6 mm, complete 1) Factory setting, can be reduced by half using the adjuster „span“ 2) At a load of < 500 ƒÇ, the unit changes over automatically to 0...20 mA or 4...20 mA. Factory setting: 0...10 V; output is protected against short circuits and excess voltage up to 24 V~ Operation The pressure difference is converted by the pressure sensor into a linear electrical signal and amplified by the measuring amplifier 3 into a continuous signal. The zero point of the characteristic curve can be raised from 0 to 2 V (or from 0 to 4 mA). At a load of < 500 ƒÇ, the unit changes over automatically to 0...20 mA or 4...20 mA. Using adjuster 1, (span = 50...100 ), the measuring range (= measuring span) can be reduced by half. Using zero 2, the zero point of the integrated pressure sensors can, if necessary, be calibrated.
