RIXOTACT_4

Product catalog summary

Overview: The RIXOTACT_4 is a device designed for measuring draft, pressure, and differential pressure, featuring an integrated three-point-step-controller and a 0-10V transmitter.

Measuring System: Utilizes the 'Ringbalance' measuring principle with a Hall sensor for magnetic-field detection. The display is an LCD with 3 1/2 digits, showing measurements in units such as Pa, kPa, daPa, mbar, mmW.C., and in.W.C. The measuring range spans from 0 to 40 Pa up to 0 to 1.8 kPa, with accuracy within +/-1.5% of span or +/-1.5 Pa. The device operates in ambient temperatures from 0 to +50 °C.

Controller: Features a three-point-step-controller with PD action. It includes two adjustable setpoints (W1/W2) from 20% to 80% of the span. Control outputs are potential-free relay contacts rated at 250V/2A. Control settings include proportional band (P), differential action (D), neutral zone (NZ), and switching frequency (F).

Transmitter: Provides an output signal of 0-10 V proportional to the measured value, with a minimum load of 2k ohms. The power supply options include 230V AC, 110/120/240 VAC, or 24V DC, with a power consumption of 3.5VA. It complies with electromagnetic compatibility standards EN50081-2 and EN50082-2.

Ordering Specifications: When ordering, specify the type (Rixotact_4), measuring range, power supply, and any options such as the overload protection device 'DZ'.

Filling Fluids and Overload Protection: The device is factory-filled with either mineral oil or synthetic oil, depending on the range. It is inherently protected to at least +/-900 Pa, with an option for additional overload protection up to +/-2.1 kPa.

Measuring Ranges: The device can be calibrated for any range between 40 Pa and 1.8 kPa. Examples of available ranges are provided, and other units such as mbar and mmW.C. are available.

Housing: The housing is made of glass-reinforced polycarbonate, suitable for wall mounting, and offers protection class IP65. It includes a hardened front glass pane and can be mounted through inner screw channels or with an attached mounting frame.
