Whether measuring flow and level or monitoring filters and pumps: The new model DPT-20 differential pressure transmitter from WIKA is suitable for many industrial processes. As a SIL-2 certified instrument, it meets the highest safety requirements.
The transmitter, with its compact design, operates with an accuracy of < ±0.065 % of span. Due to a three-dimensional temperature compensation on adjustment, it provides a reliable measuring result, even under unfavourable ambient conditions. The DPT-20 is available with measuring ranges between -10 ... +10 mbar and -16 ... +16 bar and is designed for a static pressure of up to 400 bar. Its turndown function enables very flexible use and thus economical stock-holding.
For the DPT-20, there are three communication protocols available for integration into existing systems: 4 ... 20 mA HART®, FOUNDATION™ Fieldbus or PROFIBUS® PA output signals. The differential pressure transmitter can be parameterised in two ways: via process control using DTM or EDD and configuration software, or directly on the instrument via an optional digital display
