1 General Safety Instructions

All pressure connections may only be opened after the system is
without pressure!

Observe the national regulations about safety and accident prevention , as
well as the safety instructions in this operating manual when operating the
pressure transmitter.

Any operation not described in the following instructions must not be car­ried out.

If a failure cannot be repaired, the transmitter must be switched off. The
operator must then make sure that it is only switched on again after the
failure has been repaired.

Prior to installing, starting and operating a pressure measuring instrument,
the user must ensure that the appropriate instrument has been selected
with regard to scale range and performance and that the wetted parts
material is suitable for the specific measuring conditions of the respective
application.

Serious injuries and/or damage can occur should the relevant regulations
not be observed.

Dangerous pressure media such as oxygen, acetylene, flammable gases
or liquids and toxic gases or liquids as well as instruments for refrigeration
plants or compressors etc. require attention above the standard regula­tions. Here the specific safety codes or regulations must be considered.

Ramaining pressure medium contained in the pressure element may be
hazardous or toxic. This should be considered when handling and storing
the removed pressure measuring instrument.

Repairs should only be carried out by the manufacturer. All other repairs or
modifications of the transmitter are unauthorized.

Other important safety guidelines can be found in the different sections of
this instruction manual.

2 Product Description

The UniTrans pressure transmitter can be used in level control applications as well as
for pressure measurement applications in process industr

y

. A variety of process con-

nections, measurement ran

g

es, main boards and display options result in a product

for a wide ran

g

e of applications.

2.1 Construction

The UniTrans consists of a pressure sensor, a control interface unit and a housin

g

cover with optional displa

y

. Due to this modular design, different transmitter versions

can be mounted (see “Model Ke

y

” on page 79).

2.1.1 Pressure Transducer

The pressure transducer has a piezo-resistive or thinfilm measurement cell depend­in

g

on the pressure range. The sensors are temperature compensated, and have a

hermeticall

y

welded membrane which is "helium" leak-tested. The pressure trans-

ducers do not have internal sealin

g

elements.

Pressure transducers further distin

g

uish themselves from one another based on their

pressure ran

g

es and the different materials of wetted parts. Different process

connections can be selected to serve a wide ran

g

e of applications.

Never exceed the overpressure limit of the respective pressure transducer.

2.1.2 Processing Unit

The processin

g

unit, which is integrated in the housing contains the terminal compart-

ment and the ke

y

pad used for programming the transmitter. The four keys must be

activated (unlocked) before use. Durin

g

normal operation the keypad is locked to pro-

tect data and functions previousl

y

entered. The keypad is automatically locked when

no ke

y

is hit for 10 minutes. The processing unit converts the digitalized signal from

the measurin

g

unit into a standard 4...20 mA current signal.

2.1.3 Display Unit

The indicator has four di

g

its (7-segment display) + symbols. Below it, line 1 (16-seg-

ment displa

y

) is used to display error codes and the signal’s unit of measure. The unit

of measure can be selected b

y

the operator. Measurements over 9999 can not be cor-

rectl

y

displayed. Please note this when choosing the unit (e.g. 9999 Pascal = 0,09999

bar). Additional information is displa

y

ed in lines 2 and 3 (16-segment display). The

operator can enter commands in the pro

g

ramming mode on the display unit by means

of menu

uided, clear-text prompts.

Transmitters with displays offer a larger number of programming and processing op­tions. These options include alarm status, dampin

g

, signal inversion, tank lineariza-

tion and dia

g

nostic messages.

2.2 Function

The mode of operation for si

g

nal conversion works in the same way for all versions.

The pressure transducer converts the existin

g

pressure into an electrical signal. Mi-

croelectronics further process the input si

g

nal and produce a proportional 4-20 mA

standard si

g

nal.

The displa

y

-version allows programming (parameterization) and the display of ex-

tended functions such as inversion, dampin

g

, alarm status and linearization.
