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 amplied and standardised. The output signal is proportional to the measured pressure.

6.1.2 Installing the instrument

WARNING!

GB

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

■

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 ats provided for this purpose and

using a suitable tool.

When there is a cooling element, the lower hexagon should

be used for tightening (see gure 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.

6.2 Electrical mounting

Only use original accessories. For accessories see data sheet PE 81.61.

WARNING!

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 elds.

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 t 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.

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,
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 sucient precautionary measures.

10.1 Dismounting

WARNING!

Risk of burns!

Let the instrument cool down suciently 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 ats 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!
