2. Safety
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
pressure gauge has been selected in terms of measuring range, design and
specic measuring conditions.
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.
2.1 Intended use
These pressure gauges are used for measuring pressure in UHP applications, e.g. in the
semiconductor industry or for UHP chemicals distribution systems.
The pressure gauge has been designed and built solely for the intended use described
here and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to equipment.
■
The activities described in these operating instructions may only be carried
out by skilled personnel who have the qualications described below.
GB
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowl-
edge of country-specic regulations, current standards and directives, are capable of
carrying out the work described and independently recognising potential hazards.
2.3 Special hazards
WARNING!
Residual media in dismounted instruments can result in a risk to persons, the

■
The mechanical pressure gauge of the HYDRA-Gauge is overpressure safe up to the
full scale value for a short term. However working pressure should not exceed 2/3 of the
measuring range to guarantee a long service life of the pressure gauge.
■
In any case the maximum pressures and temperatures of the process connection
according to the following chart must not be exceeded. The resulting maximum
permissible working pressures might be lower than the instrument's measuring range.

The HYDRA-Gauge is not appropriate for strong vibrations, pulsations and pressure
surges, e.g. at measuring points directly behind a pump. Appropriate pulsation dampers
and restrictor segments may be necessary.
■
The HYDRA-Gauge must not be used with aggressive ambient conditions (e.g. HCl
vapours). This may result in corrosion of the metallic parts of the HYDRA-Gauge.

4. Design and function
4.1 Description
HYDRA-Gauge is a mechanical pressure gauge of nominal size 63 in accordance with
EN 837-1. With a special diaphragm seal system it has been adapted to the special
requirements of ultrapure media distribution systems. All wetted parts are made of PFA
or TFM (modied PTFE). Final assembly, adjustment and packaging is eected under
Laminar-Flow Class 100. Standard system ll uid is KN 75, a 50/50 mixture of DI water and
isopropyl alcohol (IPA). Optionally DI water (KN 64) is used. Pressure gauge and diaphragm
seal are one unit and may never ever be separated as this may cause the system ll uid to
leak, thus destroying the measuring assembly.
4.2 Scope of delivery
Cross-check scope of delivery with the delivery note.

5. Transport, packaging ... / 6. Commissioning, operation
5. Transport, packaging and storage
5.1 Transport
GB
Check the instrument for any damage that may have been caused during transportation.
Obvious damage must be reported immediately.
5.2 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).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +60 °C (standard, KN 75)
+5 ... +60 °C (optional, KN 64)
6. Commissioning, operation
Installation instructions
The recommendations of EN 837-2 regarding selection and installation of pressure
gauges are to be observed. Installation and commissioning may only be carried out by
trained and qualied personnel. When tightening the process connections, observe the
relevant instructions and the advice of the ttings' manufacturers. The measuring instru-
ment's central nut, which is sealed with a colour point, and the threaded connection of the
pressure gauge to the diaphragm seal must not be loosened at any rate. This would cause
the destruction of the measuring assembly and the leakage of the process medium.

6. Commissioning ... / 7. HYDRA-Gauge with switch contacts
After installation the pressure gauge may
be turned by hand in order to get an optimal
read-o position.
A pressure measuring instrument with the option of an electrical contact must be
connected in accordance with the connection diagram on the instrument.
For further information see data sheet AC 08.01
360°
7. HYDRA-Gauge with switch contacts
When using the HYDRA-Gauge pressure measuring assemblies with model 830 E
electronic contacts, observe the following:
7.1 Description, application
Direct switching of small capacities which are usually required in connection with a PLC
can be realised by the inductive contact with integrated switching amplier, which is
factory-installed directly into the measuring instrument.
GB
The familiar advantages with inductive contacts, such as an especially safe contact
operation, no wear at all by proximity contact operation as well as virtually no reaction
on the measuring system, thus enabling the accuracy of the indication, are used in this
context, too.
An additional control unit is not required.
The electronic contact with 3-wire design is realised with a PNP output. The operating
voltage is DC 10 ... 30 V. The maximum switching current is 100 mA.
The model 830 E is not intrinsically safe and therefore not suitable for applications in
hazardous areas!

7. HYDRA-Gauge with switch contacts
7.2 Special requirements for the installation point
To avoid, amongst other things, switch signal "chatter", it must be ensured that the instruments are mounted free of vibration.
GB
7.3 Electrical connection
The electrical connection must only be made by qualied skilled personnel. The permissible electrical data, connection details and switching functions are given on the product
label axed to the instrument.
The connection cables are appropriately marked.
■
To connect a PLC control unit or for direct switching of small capacities
■
PNP transistor
With PNP switching apparatus, the switched output is a connection towards PLUS. The
load RL between the switched ouput and the MINUS should be selected in a way not to
exceed the maximum switching current of 100 mA.

Set pointer
adjustment key (included in delivery).
Adjustment lock
GB
The set pointers for the limit switches are freely adjustable over the full scale range. For
reasons of switching accuracy and service life of the mechanical measuring systems, the
switch points should be between 10 % and 90 % of the measuring range.

8. Maintenance and cleaning / 9. Dismounting and disposal
8. Maintenance and cleaning
8.1 Maintenance
GB
HYDRA-Gauge pressure measuring assemblies are maintenance-free.
The indicator and switching function should be checked once or twice every year.
The instrument must be disconnected from the process to check the indication and switching function with a pressure testing device.
The HYDRA double diaphragm system prevents contamination of the process medium
even in case of mechanical damage of the wetted diaphragm. In this case the process
medium will penetrate the lateral leakage bore. The instrument must be exchanged as soon
as possible.
For safety reasons repairs of already installed instruments are not possible.
8.2 Cleaning
CAUTION!
■
The HYDRA-Gauge may only be cleaned by rinsing. Any mechanical
cleaning inside the process connection may damage the separating
diaphragms.
■
Clean the instrument with a moist cloth.
■
Electrical connections must not come into contact with moisture.
9. Dismounting and disposal
WARNING!
Residual media in dismounted instruments can result in a risk to persons, the
environment and equipment.
Take sucient precautionary measures.
9.1 Dismounting
Only disconnect the pressure gauge once the system has been depressurised!
9.2 Disposal
Incorrect disposal can put the environment at risk.
Dispose of instrument components and packaging materials in an environmentally
compatible way and in accordance with the country-specic waste disposal regulations.
