Brief description
The JUMO DELOS SI high-precision, electronic pressure switch with analog output meets technical
requirements relevant to hygiene. In a readily cleanable design and with a front-flush, sealfree
measuring system, it is specifically geared to hygienic process safety standards and has
been engineered and certified in compliance with EHEDG guidelines. The nominal measuring
ranges set at the factory extend from 400 mbar to 60 bar. They can be rescaled in the ratio 1:4,
allowing the user to perform several measurement tasks with just one measuring instrument. The
following output variants are available, depending on the application: 1 x PNP or 2 x PNP switching
outputs or 1 x PNP switching output and an analog output signal. The process pressure is
visualized by a large, positively lit LC display, which changes from an amber color to red, as an
alarm function, if the nominal measuring range is exceeded (6.25% according to NAMUR). Configuration
can simply be performed on the measuring instrument, or by using the more convenient
setup program. The enclosure can be rotated +/-160° to make it easier to read, and the
display can be rotated 180° for overhead mounting. A high-temperature variant is available for
hot media up to 200°C (CIP and SIP cleaning systems).
