1 Safety instructions

Designated use

The transducer is to be used exclusively for pressure

measurement and directly related control tasks within the

load limits detailed in the specifications for the respective

maximum capacities. Use for any purpose other than the

above is deemed to be non-designated use.

Any person instructed to carry out installation, commis-

sioning or operation of the device must have read and

understood the Operating Manual and in particular the

technical safety instructions.

In the interests of safety, the transducer should only be

operated by qualified personnel and as described in the

Operating Manual. It is also essential to comply with the

legal and safety requirements for the application con-

cerned during use. The same applies to the use of

accessories.

The transducer is not intended for use as a safety com-

ponent. Please also follow the instructions in the "Addi-

tional safety precautions" section. Proper and safe opera-

tion requires proper transportation, correct storage, siting

and mounting, and careful operation.

Operating conditions

SThe transducer must not be modified from the design

or safety engineering point of view except with our

express agreement. In particular, any repair or solder-

ing work on motherboards (exchanging components)

is prohibited.

SThe data in the technical data sheets must be com-

plied with when using the transducer. The respective

specified maximum loads in particular must never be

P8WT

4 A1643-3.0 en/de/fr

exceeded. The following are set out in the technical

data sheets and must not be exceeded:

- Limit loads

- Permissible dynamic loads

- Temperature limits

SThe transducer is maintenance-free.

SA functional measurement chain is only created when

the (passive) transducer is connected to an amplifier.

Ensure that electromagnetic compatibility or integra-

tion in a suitable EMC shielding concept is provided.

To do this:

- Connect the cable shield extensively to the input of

the amplifier.

- Connect the measuring body, i.e. the housing, to

the ground.

Important

The transducer cable shield is not connected with the

housing (ground).

Qualified personnel

Qualified persons means persons entrusted with the

installation, fitting, commissioning and operation of the

product who possess the appropriate qualifications for

their function.

This includes people who meet at least one of the three

following requirements:

SKnowledge of the safety concepts of measurement

and automation technology is a requirement and as

P8WT

A1643-3.0 en/de/fr 5

project personnel, you must be familiar with these

concepts.

SAs measurement or automation plant operating per-

sonnel, you have been instructed how to handle the

machinery. They are familiar with the operation of the

equipment and technologies described in this docu-

mentation.

SAs commissioning engineers or service engineers,

they have successfully completed the training to qual-

ify them to repair the automation systems. They are

also authorized to activate, ground and label circuits

and equipment in accordance with safety engineering

standards.

Working safely

SError messages should only be acknowledged once

the cause of the error is removed and no further dan-

ger exists.

SAutomation equipment and devices must be designed

in such a way that adequate protection or locking

against unintentional actuation is provided (e.g.

access checks, password protection, etc.).

SAfter making settings and carrying out activities that

are password-protected, ensure that any controls that

may be connected remain in a safe condition until the

switching performance of the device has been tested.

Additional safety precautions

Additional safety precautions to meet the requirements of

the relevant national and local accident prevention regu-

lations must be taken in plants where malfunctions could

cause major damage, loss of data or even personal

injury.

P8WT

6 A1643-3.0 en/de/fr

The scope of supply and performance of the transducer

covers only a small area of measurement technology.

Before starting up the device in a system, a project plan-

ning and risk analysis must first be implemented, taking

into account all the safety aspects of measurement and

automation technology so that residual dangers are mini-

mized. This particularly concerns personal and machine

protection. In the event of a fault, the relevant precau-

tions must establish safe operating conditions.

General dangers of failing to follow the safety

instructions

The transducer corresponds to the state of the art and is

failsafe. The transducer may give rise to residual dangers

if it is inappropriately installed or operated.

2 Markings used

2.1 Symbols on the transducer

CE certification

The CE mark enables the manufacturer to guarantee that

the product complies with the requirements of the rele-

vant EC directives (the Declaration of Conformity can be

found on the HBM website (www.hbm.com) under

HBMdoc).

2.2 The marking used in this document

Important instructions for your safety are specifically

identified. It is essential to follow these instructions in

order to prevent accidents and damage to property.

Symbol Significance

Important

This marking draws your attention to important infor-

mation about the product or about handling the prod-

uct.

Tip

This marking indicates application tips or other infor-

mation that is useful to you.

Emphasis

See …

Italics are used to emphasize and highlight text and

identify references to sections, diagrams, or external

documents and files.

4 Function

The P8WT type series transducers are based on an

absolute pressure transducer for the 0 …500 bar mea

suring range. They are suitable for measuring static and

dynamic liquid and gas pressures. Whatever the mount-

ing position, these small and handy transducers can be

used even where space is tight.

The P8WT pressure transducers are optionally equipped

with M8 internal thread or G1/8 connectors.

All commercial hydraulic screw connections can be com-

bined with the P8WT for installation.

5 Mechanical installation

Before installing the P8WT, check that the threaded con-

nector and the thread in its mating component are sound

and without burrs. The parts must be easy to screw

together.

The transducer can be screwed in in any position

required. If the transducer is used to measure dynamic

pressure characteristics in liquids, it should be installed

with the pressure connection pointing upward, so that it is

not possible for an air cushion to build up in the measure-

ment tube. This would hinder the measurement of

dynamic signals and cause the transducer to heat up to

unpermitted levels.

Mounting

"Coat the threaded connector of the hydraulic connec-

tion with sealant.

"Before electrical connection, screw the transducer

onto the hydraulic connector and tighten the connec-

tion.

6 Electrical connection

The following can be connected for measurement signal

conditioning:

SCarrier-frequency amplifier

SDC amplifier

designed for strain gage measurement systems.

The transducers are supplied in the standard version in a

six-wire configuration with open cable ends.

Important

The cable shield is not connected with the transducer

housing.

Tip

Route the connection cable so that any condensed water

or dampness forming on the cable can drip off. It must

not be conducted to the transducer (use small loops).

Also ensure that no moisture can penetrate the open

cable ends.
