Transmitter DULCOMETER® DULCOPAC
The transmitter DULCOMETER® DULCOPAC is a complete PID controller for the key measuring parameters in water treatment. It can be installed on a top hat rail inside a control cabinet.
The compact transmitter for installation in control cabinets.
The DULCOPAC transmitter in a DIN housing is intended for installation on a top hat rail (in a control cabinet). It measures and regulates the measured variables The physical variables to be determined by measuring. more in the glossary in aqueous solutions: pH, ORP, chlorine and conductivity.
With the measured variables The physical variables to be determined by measuring. more in the glossary pH and ORP, it is possible to select between a DULCOPAC transmitter with a highly-ohmic coaxial input (direct connection of a pH/ORP sensor) or a 4-20 mA two-wire input. A transmitter is also needed when connecting pH or ORP via 4-20 mA (part no. 809126 for pH and part no. 809127 for ORP).
Two analogue outputs (0/4...20 mA) are available for recording purposes and two potential-free low voltage relays with a changeover contact for control of metering pumps. The analogue outputs are galvanically isolated. The DULCOPAC is operated and configured using buttons and the integrated LC display via codes.
The power supply is provided via a special DULCOPAC power supply and can feed up to 10 DULCOPAC units. It provides the requisite galvanic isolation to the mains power supply.
