2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the appropriate pressure gauge has been selected in terms of measuring range, design and

specic 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 qualication

WARNING!

Risk of injury should qualication be insucient!

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 qualications described below.

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-specic 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 environment and equipment.

Take sucient precautionary measures.

Permissible working conditions

Ambient temperature +5 ... 60 °C Process temperature +5 ... 60 °C

■

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 (modied PTFE). Final assembly, adjustment and packaging is eected 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

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 qualied 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 amplier, which is

factory-installed directly into the measuring instrument.

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.

7.3 Electrical connection

The electrical connection must only be made by qualied skilled personnel. The permissible electrical data, connection details and switching functions are given on the product

label axed 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.

8. Maintenance and cleaning / 9. Dismounting and disposal

8. Maintenance and cleaning

8.1 Maintenance

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 sucient 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-specic waste disposal regulations.
