WIKA operating instructions dierential pressure gauge with piston
1. General information
1. General information
The dierential pressure gauge described in the operating instructions has been
designed and manufactured using state-of-the-art technology.
All components are subject to stringent quality and environmental criteria during
production. Our management systems are certied to ISO 9001 and ISO 14001.
These operating instructions contain important information on handling the
dierential pressure gauge. Working safely requires that all safety instructions
and work instructions are observed.
Observe the relevant local accident prevention regulations and general safety
regulations for the dierential pressure gauge's range of use.
The operating instructions are part of the product and must be kept in the
immediate vicinity of the pressure gauge and readily accessible to skilled
personnel at any time.
Skilled personnel must have carefully read and understood the operating
instructions prior to beginning any work.
The manufacturer's liability is void in the case of any damage caused by
using the product contrary to its intended use, non-compliance with these
operating instructions, assignment of insuciently qualied skilled personnel or
unauthorised modications to the dierential pressure gauge.
The general terms and conditions contained in the sales documentation shall
apply.
Subject to technical modications.

pressure gauges in accordance with EN 837-2.
Check the compatibility with the medium of the materials
subjected to pressure!
In order to guarantee the measuring accuracy and long-term
stability specied, the corresponding load limits must be
observed.
Non-observance can result in serious injury and/or damage to
the equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.

4. Design and function
Description
Pressures p1and p2 are given in the ⊕ and ⊖ measuring chambers, separated
by the magnetic piston under pressure(or magnetic piston and separating
diaphragm for model 700.02).
The dierence in pressure causes an axial movement (deection) of the piston
supported by the compression spring.
The deection resulting from this is taken up by a ring magnet found on the
instrument pointer and appropriately displayed. This design combines the
advantages of complete separation of the measuring system and the indication
while eliminating any leakage to the exterior.
For model 700.01 the volume ow from the ⊕ measuring chamber to the ⊖
measuring chamber is minimised by the constructive design and will not interfere
with standard processes.
These instruments are mainly intended for gas/air supply and preparation appli-
cations where no magnetic particles are involved.

May be retrotted on site as required.
Alignment of the front bezel (A) by means of the stamped cams to the grooves
found on the case circumference. Push front bezel on the case until it snaps into
position.
5.2 Minimum or maximum drag pointer (see illustrations)
The drag pointer (B) serves to monitor and control the miniumum or maximum
occurring dierential pressure.

7. Commissioning, operation
Mechanical connection
The installation of the dierential pressure gauge is made following the installation
recommendations for pressure gauges in accordance with EN 837-2 /7.
Mounting of the process connection according to axed symbols ⊕ and ⊖
⊕ high pressure, ⊖ low pressure
■
Hold against the connection pieces in the case of installation by means of
17 mm screw spanner (installation without holding against the connection
pieces may cause thet measuring system to get loose).
■
The maximum permissible medium/ambient temperature must not be
exceeded
■
Prior to the installation of the pressure gauge, clean the measuring lines
thoroughly by tapping and blowing or rinsing
■
Mount and operate the measuring instruments free from vibration
■
Protect measuring instruments from contamination and high temperature
changes
To avoid foreign matter in the measuring system and the resulting damage to the
system, the pressure gauge must be mounted above the connector. For measuring
media containing suspended particles model 700.02 should be used.
6. Transport, packaging and storage
5.1 Transport
Check pressure gauge for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
6.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g.
change in installation site, sending for repair).
6.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +70 °C (optional: -40 … +70 °C)

should be mounted by means of appropriate fastening elements for wall mounting,
or, if necessary, with a capillary.
