Ringbalance pressure controller

Combines low draft, pressure and differential pressure measurement with integrated three-point step control.

Three-point step control

Provides PD action for applications requiring open, close or hold control behaviour.

Selectable setpoints

Two setpoints, W1 and W2, are adjustable from 20% to 80% of span and selectable via terminals.

Configurable control response

Proportional band, differential action, neutral zone and switching frequency can be adjusted to suit the application.

0–10 V transmitter output

Provides a signal proportional to the measured actual value for external monitoring or signal use.

Configurable low-pressure range

Measuring range can be selected from 0…40 Pa to 0…1.8 kPa, including ranges within these limits.

Overload protection option

DZ overload protection can be specified where pressure spikes or abnormal overload conditions may exceed standard limits.

Range selection

Support selecting a measuring range so expected setpoints sit appropriately within the span

Output and supply selection

Support confirming the 0–10 V transmitter output and power supply requirements

Overload protection

Advice on whether DZ overload protection should be considered where pressure spikes may occur
