2. Safety
2. Safety
WARNING!
GB Before installation, commissioning and operation, ensure that the appropriate pressure transmitter has been selected in terms of measuring range, design and specific measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
WARNING!
■■ Open the connections only after the system has been depressurised.
■■ Observe the working conditions in accordance with chapter 3 "Specifications".
Further important safety instructions can be found in the individual chapters of these operating instructions.
2.1 Intended use
The pressure transmitter is used to convert pressure into an electrical signal.
With hydrogen applications, use is only permitted when a medium and ambient temperature of 30 °C is not exceeded.
For applications with direct contact with foodstuffs this pressure transmitter is not suitable.
The instrument has been designed and built solely for the intended use described here, and may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.Improper handling or operation of the pressure transmitter outside of its technical specifications requires the instrument to be taken out of service immediately and inspected by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

2.2Personnel qualification
WARNING!
Risk of injury should qualification be insufficient! GB
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 qualifications 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 knowledge of country-specific regulations, current standards and directives, are capable of carrying out the work described and independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, flammable or toxic gases or liquids, and refrigeration plants, compressors, etc., in addition to all standard regulations, the appropriate existing codes or regulations must also be followed.
WARNING!
Residual media in dismounted pressure transmitters can result in a risk to persons, the environment and equipment.
Take sufficient precautionary measures.

4. Design and function / 5. Transport, packaging and storage
4. Design and function
4.1 Description
The prevailing pressure is measured at the sensor element through the deformation of a diaphragm. By supplying power, this deformation of the diaphragm is converted into an electrical signal. The output signal from the pressure transmitter is amplified and standardised.The output signal is proportional to the measured pressure.
4.2 Scope of delivery
■■ Pressure transmitter ■■ Test report
■■ Certificates (option)
■■ Mating connector (option)
Cross-check scope of delivery with delivery note.

5.Transport, packaging and storage
5.1Transport
Check the pressure transmitter 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:-40 ...+70 °C
■■ Humidity:67 % relative humidity (no condensation)
WIKA operating instructions pressure transmitter, model S-20 |
15 |
5. Transport, packaging and storage
Avoid exposure to the following factors:
■■ Direct sunlight or proximity to hot objects
■■ Mechanical vibration, mechanical shock (putting it down hard)
GB ■■ Soot, vapour, dust and corrosive gases ■■ Humid or wet environment
■■ Potentially explosive environments, flammable atmospheres
Store the pressure transmitter in its original packaging in a location that fulfils the conditions listed above.
WARNING!
Before storing the instrument (following operation), remove any residual media.This is of particular importance if the medium is hazardous to health, e.g. caustic, toxic, carcinogenic, radioactive, etc.

|
WARNING! |
|
|
Risk of burns! |
|
|
The cooling element can be hot as a result of previous use. Allow the cooling element to cool beforehand. |

The sealing faces at the instrument have to be undamaged and clean. |
|
|
Parallel threads |
Tapered threads |
|
per EN 837 |
per DIN 3852-E |

Correct sealing of the process connections with parallel threads at the sealing face must be made using suitable flat gaskets, sealing rings orWIKA profile sealings.
For sealing process connections with tapered threads, the sealing must be made in the threads using additional sealing material, e.g.PTFE tape (EN 837-2).

|
WARNING! |
GB |
Risk of burns! |
The cooling element can be hot as a result of previ- |
|
|
ous use. Allow the cooling element to cool before- |
|
hand. |
■■ When screwing the instrument in, the force required to do this must not be applied through the case or the cap ring, but only through the spanner flats provided for this purpose and using a suitable tool.
When there is a cooling element, the lower hexagon should be used for tightening (see figure a "Mounting cooling element")
The correct torque depends on the dimensions of the process connection and the gasket used (form/material).
■■ When screwing in, do not cross the threads.
■■ For heat dissipation, the cooling element must not be insulated.
■■ If the instrument is mounted upside down, it must be ensured that no water can collect on the electrical connection and on the cap ring. Water can block the pressure compensation diaphragm.

6.2Electrical mounting
Only use original accessories. For accessories see data sheet PE 81.61.
WARNING! |
GB |
The instrument shield does not act as a protective conductor for protection of personnel, rather as a |
functional ground in order to shield the instrument from electromagnetic fields.
6.2.1 Connection assembly
■■ For instruments with ratiometric output signals, a shielded cable must be used. The cable shield must be grounded, if the cable is longer than 30 m or leaves the building.
■■ Use a cable with suitable characteristics for the particular operating conditions. ■■ For cable variants, strain relief must be employed.
■■ Cable with ventilation tubes must be vented to atmosphere. ■■ The instrument must be earthed via the process connection!
■■ Select a cable diameter that matches the cable gland of the plug. Make sure that the cable gland of the mounted plug has a tight fit and that the seals are present and undamaged.Tighten the threaded connection and check that the seal is correctly seated, in order to ensure a tight seal.
■■ For cable outlets, make sure that no moisture enters at the cable end. ■■ Pin assignment see test report.
6.2.3 Setting up a voltage supply
The voltage supply is made via a power supply unit or a control unit which provides the energy limitation.
The power supply for the pressure transmitter must be made via an energy-limited electrical circuit in accordance with section 9.4 of UL/EN/IEC 61010-1, or an LPS to UL/EN/IEC 60950-1, or class 2 in accordance with UL1310/UL1585 (NEC or CEC).The power supply must be suitable for operation above 2,000 m should the pressure transmitter be used at this altitude.

9. Faults / 10. Dismounting, return and disposal
CAUTION! |
|
If faults cannot be eliminated by means of the measures listed above, shut down the pressure transmitter |
|
immediately, and ensure that pressure and/or signal are no longer present, and secure the instrument from |
|
being put back into operation inadvertently. In this case, contact the manufacturer. If a return is needed, |
GB |
please follow the instructions given in chapter 10.2 "Return". |
10. Dismounting, return and disposal
WARNING!
Residual media in dismounted pressure transmitters can result in a risk to persons, the environment and equipment.Take sufficient precautionary measures.
10.1 Dismounting
WARNING!
Risk of burns!
Let the instrument cool down sufficiently before dismounting!
During dismounting there is a risk of dangerously hot pressure media escaping.
When removing the instrument, the force required to do this must not be applied through the case or the cap ring, but only through the spanner flats provided for this purpose and using a suitable tool (see chapter 6.1.2 "Installing the instrument").
When there is a cooling element, the lower hexagon should be used for unscrewing (see chapter 6.1.2 "Installing the instrument")
Only disconnect the pressure transmitter once the system has been depressurised!
