RIXOTACT_4 Measuring draft, pressure and differential pressure + integrated Three-Point-Step-Controller + intergrated Transmitter 0-10V Measuring System "Ringbalance" measuring principle Display Pa, kPa, daPa, mbar, mmW.C., in.W.C. Measuring ranges from 0...40 Pa to 0...1.8 kPa (0.15"W.C. - 7"W.C.) and any range within these limits Measuring pick-up Hall - sensor (magnetic-field sensor) Accuracy Ambient temp. Polycarbonate light-grey, protection class IP65, Dimensions: 180 x 255 mm, 165 mm deep Controller Three-point-step-controller with PD action Setpoints W1/W2 two setpoints, adjustable from 20...80% of span, selectable via terminals 3-4 upper position: LCD shows the actual value "X" lower position: LCD shows actual setpoint "W" Control outputs potential-free relay contacts, rated at 250V/2A Control Settings P - proportional band, D - differential action, NZ - Neutral zone (deadband), F - switching (pulse-) frequency Transmitter Output signal 0-10 V, proportional to the measured (actual) value "X"; min.load: 2k ohms 230V AC (110/120/240 VAC; 24V DC); 3.5VA Electromagnetic Compatibility according to EN50081-2 (emmission) and EN50082-2 (immunity) Terminal Diagram Ordering specification 1. Type 2. Measuring range For best results, select such a range that your estimated setpoints lie approximately in the middle (mid-third) of the measuring range. 3. Power supply please specify Overload Protection Device "DZ" (Bypass) see next page Control output Setpoints W1/W2: open = W1 shorted = W2 Power supply

Measuring Ranges, Filling Fluids Overload Limits Measuring Ranges Filling Fluids Note: All Ringbalance instruments are factory-filled. The type of oil need not be mentioned in the order. Each instrument is calibrated individually, according to order. A factory calibration certificate is supplied to each unit. The ranges shown below are examples only. Any desired range between 40 Pa (0.15"W.C.) and 1.8 kPa (7"W.C.) is available.
