## DPM8180-2 Process Meter Cé 

## **features** 

- CE approved and marked 

- Large (14.2mm) red LED characters Choice of inputs (4-20mA, 10-50mA, 1-5V, 0-10V) Engineering read-outs e.g. pressure, flow, level Offset and span adjustable 

- Adjustable sensor excitation output (5-24V dc) Display hold facility 

The  DPM8180 is a low cost, high performance mains powered signal process panel meter. Engineering units such as pressure, flow, temperature and level can be displayed. 

It has an adjustable, 5-24V dc (50mA) excitation supply for powering transmitters and active transducers without the need for an external supply. 

User calibration is performed by adjusting DIP switches and multi-turn potentiometers to choose the input format and set the corresponding display values.

About Novapart

Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
