Introduction
The JUMO DELOS SI high-precision, electronic pressure switch with analog output meets technical re-
quirements relevant to hygiene. In a readily cleanable design and with a front-flush, seal-free measuring
system, it is specifically geared to hygienic process safety standards. 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× PNP or 2× PNP switching
outputs or 1× PNP switching output and an analog output signal.
The process pressure is visualized by a large, positively lit LC display.
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).
The device is certified according to EHEDG in the versions with process connections (clamp) DN 25, 32,
40, and 50 as well as JUMO PEKA.
CAUTION!
The pressure transmitter is used for pressure measurement in gases and liquids. It can be a
source of risk if not used as intended.
The device may only be installed, connected and started up by qualified and authorized personnel ob-
serving these operating instructions, the applicable standards, and the legal requirements (depending
on the application).
The device does not meet the requirements "Equipment with safety function" as per the Pressure Vessel
Directive 2014/68/EU; see Technical Data.
If you experience difficulties during startup, please contact the manufacturer.
Depending on its design, the device measures the relative or absolute pressure in liquid and gaseous
media.
The pressure is displayed digitally.
