Beschreibung

The DPU91 transmitter provides a single channel interface for many different parameters including flow, pH/ORP, conductivity/resistivity, salinity and temperature. The DPU91-BC transmitter has the added capability of supporting the batch module for batching control. The extra-large (100 mm²) backlit display can be viewed at 4 to 5 times the distance of traditional transmitters. The display shows separate lines for units of measure, main and secondary measurements as well an analogue bar graph.

The DPU91 is offered in both panel or process-mount versions. Both models can run on 12 to 32 Vdc power (24 Vdc nominal) and have 4 to 20 mA outputs. Designed for complete flexibility, plug-in modules allow the unit to easily adapt to meet changing application needs. Optional modules include relay, direct conductivity/ resistivity, batch and a PC communications configuration tool. The unit can be used with default values for quick and easy installation or can be customised with labels, adjustable minimum and maximum dial settings, units of measure and resolution.
