  • Application
  • Description

Application

  • Electronic volume flow controller Universal with static differential pressure transducer for use with volume flow rate measuring units
  • For applications with polluted extract air, e.g. with fluff, sticky particles or aggressive substances
  • Parameters are factory set
  • On-site adjusting is not required
  • For this application the Universal controller is only used for measuring the differential pressure and for transforming the measured value into a linear voltage signal. Connections for setpoint value signal and actuator are not relevant, and neither are the corresponding technical data.
  • Volume flow rate actual value is available as linear voltage signal

Parts and characteristics

  • Sensor for static differential pressure measurements

Maintenance

  • Zero point correction once per year is recommended

Functional description

The volume flow rate is determined by measuring the effective pressure. For this reason the measuring unit is fitted with an effective pressure sensor.

The static differential pressure transducer (diaphragm pressure transducer) transforms the effective pressure into a voltage signal. The volume flow rate actual value is hence available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal volume flow rate (Vnom).
