Appendix Exd.01

5.3. Measurements of operating temperature of transmitter

5.3.1. After installing the DPT-2000ALW transmitter for the medium maximum expected temperature and

expected the maximum ambient temperature measure out Tp temperature of the most hot place on the
surface of transmitter and determine the temperature transmitter class or a maximum surface
temperature according to p. 5.4.

When measuring the warmed media, above ambient, is recommended to determine the temperature of the
stub while is screwed into the transmitter or at the wall of the pipe or tank as shown below.

5.3.2. When medium is heated above ambient temperature it is allowed to determine the temperature class
of the transmitter or the maximum surface temperature Tp through the adoption of a maximum
temperature of the medium which provides the technological process. Measurement of Tp isn’t then
necessary.
If during the measurement of Tp for maximum temperature expected for the medium is not possible to
ensure the maximum expected ambient temperature after the measurement of Tp
one can estimate the potential growth in temperature Tp due to the increase of ambient temperature.

5.3.3. If the other elements of the plant have or may have a temperature higher than the highest temperature Tp
on the transmitter, security conditions must be ensured in accordance with accepted principles in such cases

5.4. Determination of the transmitter temperature class T * for gas and the maximum surface temperature

1. Determine the temperature class of the transmitter for the gas or the maximum temperature for

combustible dust depending on the temperature Tp from the formula:

T*Tp+0,1Tp+5K for class T3..T6

T*Tp+0,1Tp+10K for class T1, T2

2. Determine the maximum surface temperature transmitter for combustible dust from the formula:
T*Tp+0,1Tp

3. The following table contains the values of permissible ambient temperature depending on the

temperature Tp and temperature class of the transmitter.

In the case of significant increase in medium temperature measurement of Tp must be executed again and
again must be specified the temperature class for the gas or the maximum surface temperature
combustible dust.

5.5. With regard on kind of casing material (light alloy with large aluminium content), the user is obliged to
assure, that possibility of hitting casing does not step out in place of transmitter installation.

5.6. In transmitter casing are two holes to assembly of cable intakes from thread M20x1,5 or 1/2 NPT.

5.7. Normally transmitters are delivered without installed glands but with blank plugs (corks) in the second
hole. They are at table 1 and table 2 at list of packing glands and plugs agreeable with production
documentation and accepted by certificate station. Customer should install packing glands according to
tables 1 and plugs according to tables 2 (if plugs aren’t installed) or other accordance with flame-proof
standards.

5.8. It is necessary apply a shield cable or without shield cable with round cross-section in protection from
elastomer, not moisture absorbing, for example: YKSLY 2 * 1, YnTKSYekw 1 * 2 * 1, LIYCY 2 * In case
of need of use cable about different building customer should co-ordinate this with transmitters
manufacturer to choose intakes with cable diameter.

5.9. The general principles of connecting and the exploitation of transmitter in Exd realization should be

compatible with principles and relating standards for Exd casing devices how in p.2.1, in this including
also : EN600079-14, EN60079-17.

5.10. During service must be made a check of the tight fastening of covers and the packing glands and the
fastening of the cable in the glands. The casing and supply line must be inspected for mechanical
damage, and the transmitter rating plate for legibility. Periodic checks should also be made of the
diaphragm, which should not carry signs of damage. During maintenance it is recommended that the
threads of the covers be lubricated with non-acid vaseline.

Because of the transmitter damage possibility, the ambient temperature should not be allowed to
become higher than 80C, even when there is no explosion risk.

User can find them at www.delta-controls.com

5. Permitted input parameters (based on data from the FTZÚ 14 ATEX

certificate, and certification documentation).

The transmitters should be powered via the associated power feeding and measurement devices
provided with the relevant intrinsic-safe certificates. The parameters of their outputs to the danger zone
should not exceed the limit power supply parameters for the below specified transmitters.

Temperature classes T4, T5, or T6 depend on the input power and maximum ambient temperature – see p.

5.1, 5.2, 5.3.The ambient temperature range is reduced to Ta = -20ºC to +60ºC if the devices is installed as
group I M1 equipment.
External connections are made via integral terminals and cable glands which must be of certified type if they
are mounted on the version f or combustible dust hazard application.

5.1. - for power supply with a “linear“ characteristic
Ui = 30V Ii = 0,1A Pi = 0,75W Ta ≤ 80ºC and T4, Ta  70C and T5, Pi = 0,45W Ta ≤ 40ºC and T6
Power supply with a “linear” characteristic may be e.g. a typical barrier with parameters

Uo = 28V Io = 0.093A Rw = 300.

Fig.1. Power supply from a source with “linear” characteristic

5.2. – for power supply with a “trapezial” characteristic

Ui = 24V Ii = 50mA Pi = 0,6W Ta  80°C and T5 and Pi = 0,45W Ta  40°C and T6

Example of power supply from a source with “trapezial” characteristic (see Fig. 2).

Fig. 2. Power supply from a source with “trapezial” characteristic

If Uo < then parameters Uq, Io, Po are interrelated as follows:

UQ = , Rw = , P0 = for U0 ≤ 1/2U

5.3. - for power supply with “rectangular” characteristic
Ui = 24V Ii = 25mA Pi = 0,6W Ta  80C and T5

The supply of power from a source with a “rectangular” characteristic means that the voltage of the Ex power

supply remains constant until current limitation activates.

The protection level of power supplies with a “rectangular” characteristic is normally “ib”.
The transmitter powered from such a supply is also a Ex device with protection level “ib”.

Example of practical provision of power supply.

– use a stabilized power supply with Uo=24V with protection level „ib” and current limited to Io=25mA.

6. How to connect Ex transmitters DPT-2000ALW.

The transmitter and other devices in the measuring loop should be connected in accordance
with the intrinsic-safety and explosion-safety regulations and the conditions for use in
dangerous areas.

Failure to observe the intrinsic-safety regulations can cause explosion and the resulting hazard
to people.

The transmitter is equipped in additional communication resistor RD = 240 Ω.
During normal operation terminals <Signal –> and <Test –> are shorted.
RD resistor is used when you wish to communicate with the transmitter locally (from its terminals) and
Ro < 250. Terminals <Signal –> and <Test –> must be opened.

Transmitter electrical installation should be realised with engineering standard requirements.

It is not allowed to repair or otherwise interfere with the transmitter’s electrical circuits in any

way. Damage and possible repair may be assessed only by the manufacturer or another
authorized party.
