Användning och kort beskrivning
Transmitter för tryck och nivå

Transmitterserien ETP är framtagen speciellt för
användning inom livsmedels/läkemedelsindustri,
papper och cellulosa och många andra sammanhang
där en nogrann och hygienisk transmitter krävs. Alla
synliga ytor och även processanlutningarna är utförda
i korrosionssäkra material. Transmitterns släta och
rena design innbär en produkt som är lätt att hålla
ren. Transmitterns kapslingsklass IP67 innebär att
den kan användas i dammiga och blöta miljöer.
Trycket mäts med hjälp av en piezo-resistiv sensor
och omvandlas därefter, i elektroniken, till en 4-20 mA
signal eller fältbusskommunikation. Processtrycket
mäts med ett för respektive anslutning direktanslutet
mätmembran. Membranets tryck överförs till sensorn
via ett kapillärrör (se bild 1). Kapillärröret och
transmitterns ”hals” gör att elektronikhuset värms upp
väldigt lite vid höga mediatemperaturer. Systemet är
fyllt med en livsmedelsgodkänd silikonolja.
Silikonoljevolymen är så liten som 0,25 ml.
Transmitterns mätområde kan justeras inom vida
gränser. Justerdonen är placerade i transmitterns
anslutningsutrymme under ett lättöppnat skruvlock.
Elektroniken för mätvärdesbehandling och omvandling
till utsignall finns i fyra utföranden, antingen enbart 4-
20 mA, ETP90A, eller med kommunikation, ETP90H/
PA/FF. Versionerna med kommunikation kan kommu-
nicera med HART via 4-20 mA signalen eller via Profibus PA alternativt
Foundation Fieldbus kommunikation. HART kommunikationen använder en
standardiserad typ av överföring kallad FSK (Frequecy Skift Keying). Med
hjälp av en PC med ett FSK modem kan transmittern enkelt konfigureras och
underhållas. Lämplig PC mjukvara är tex. DOX9 eller Smartvision. En stan-
dardiserad HART handterminal kan också användas för konfigurering och
underhåll av de viktigaste parametrarna i ETP90H.

Application and brief description

Transmitter for pressure and level

The transmitter type ETP has been designed especially
for use in the food, pharmaceutical, pulp and paper and
beverages industry. All visible surfaces as well as the
process connections are made of corrosion-proof mate-
rial. The smooth case surfaces can be cleaned easily.
Due to its sealing conforming to IP 67 the case is
suitable for damproom installation.
The pressure value is measured using a piezo-resistive
sensor, and then converted electronically into the 4...20
mA transmission signal or fieldbus communication. The
process value is measured with a flush-mount diaphragm
and transmitted to the sensor via a capillary tube (see
Figure 1). The capillary tube and the transmitter ”neck”
prevents the electronic housing from to high temperatures
due to high media temperatures. The system has a
bubble-free liquid filling approved for use with food. The
filling volume is as low as 0.25 ml. The measuring range
can be adjusted within wide ranges. The adjusters are
accommodated in the connection head of the case.
The electronic system for measured value processing and
conversion into the output signal is realized either as an
4-20 mA, ETP90A, or as a system with communication,
ETP90H/PA/FF. ETP90H is HART compatible for
frequency-shift keying at any chosen point of 4...20 mA
transmission. ETP90PA coomunicates with Profibus PA
and ETP90FF with Foundation Fieldbus.  A PC with a

special software and an FSK modem for frequency shift keying are required
for HART communication, allowing for convenient menu-guided configuration
of the transmitter. ETP90H can be configurated with a standard hand held
HART terminal or with a PC and the software DOX9 or Smartvision. If a PC is
used it has to be connected to the Transmitter through an FSK modem.

Transmitter for differential pressure

This transmitter has a central piezo-resistive sensor connected to the
membrane chambers via two capillary tubes.
