1. INTRODUCTION
This manual is only applicable to the PYRP-2000ALW, PYRP-2000ALW Safety,
PYRD–2000ALW, PYRD–2000ALW Safety, PYRD–2200ALW, PYRD-2000GALW and

transmitters with normal and Exi certification.
2. SAFETY
Read this manual carefully before installing, commissioning and operating the
transmitter.
Installation and maintenance should be carried out by qualified staff having the
required authorisation to install electrical and measuring devices.
The transmitter should used as intended within permissible parameters.
Power source must be disconnected before installing or removing the transmitter.
No repairs or alterations to the transducer electronic system are permitted. Only
the manufacturer or a facility authorised by the manufacturer may assess damages
and repair the device (if possible).
Do not use damaged instruments. In case of failure, the device must be
disconnected.
If the equipment is used in Ex zones, the technical requirements specified in this
manual and applicable local (national) regulations must be followed.

overvoltage protection in which ground isolated power supply should be used.
Figure 1. Sample transmitter nameplate with common Exi and Exd designation
5. TRANSMITTER DESIGN
The basic transmitter components are: an enclosure in 316 (1.4401) stainless steel or
aluminum, measuring head where a pressure signal is converted to an electrical signal, and
an electronic module converting the signal from the head to an output signal. Transmitters in
aluminum enclosures are permitted for groups II and III, and transmitters in steel enclosures
are permitted for groups I, II and III.

MAN.PYRP.PYRD.EX.001
Revision A.February 2020 7
6. ELECTROSTATIC HAZARDS
The paint, plastic nameplate and diaphragm seals coated with PTFE form a non-conducting
layer applied on a conducting base of enclosure or diaphragm seals. Transmitters with this
design in a dust-explosion zone should be installed in a place where electrostatic charging is
impossible, in particular by contact with electrically charged dust falling off or blown from
neighbouring devices.
7. SPECIAL CONDITIONS OF USE
a) The maximum temperature of the external heating source cannot heat the transmitter
above the maximum declared ambient temperature.
b) Some gaps of flameproof joint are smaller and longer than those required in table 3 of EN
60079-1 (see Table 8).
c) In hazardous dust applications, transmitters with painted aluminum enclosures as well as
transmitters equipped with plastic nameplate and PTFE-coated diaphragm separator
components should be installed in way that prevents electrostatic charging specified in
accordance with point 6.
d) A diaphragm seal or similar with titanium components must be protected from mechanical
impacts.
e) An intrinsically safe transmitter version with surge arrester, marked on the nameplate as
“SA” does not meet the requirements of clause 10.3 of EN 60079-11 (500Vrms). The
device should be installed in accordance with point 12.
f) If a transmitter with a nameplate containing dual certified designs is used, the applied
protection type must be permanently marked on the nameplate before installation (see
Figure 1).
g) For a transmitter with a flameproof enclosure, the diaphragm should not be exposed to
damage during transmitter installation and operation. The transmitter diaphragm is made
of stainless steel, Hastelloy or tantalum and must not be exposed to contact with a
medium that may damage it.
h) Galvanically separated part of apparatus within the measuring head is electrically
connected to the enclosure. This should be taken into account when installing the
apparatus with remote measuring head and cable.

8. TRANSMITTER PROTECTION LEVEL (EPL) AND
HAZARDOUS AREAS
Ga/Gb (Da/Db) EPL protection level allows the transmitter to be installed in Zone 1 (21) or 2
(22), and the transmitter process connectors can connect to Zone 0 (20). Gb (Db) EPL
protection level allows the transmitter and process connector to be installed in Zone 1 (21) or
2 (22). Da EPL protection level allows the transmitter and process connector to be installed in
Zone 20 or 21. Transmitters for mining applications Mb should be turned off if explosion hazard
occurs.

As standard, the transmitters are manufactured for explosive gas atmospheres.
A customer can also order a transmitter for explosive dust atmospheres and for
mining applications.
Transmitters with common Exi and Exd designation, as presented in Figure 1,
become intrinsically safe transmitters when Exi field is permanently marked.
