1DESCRIPTION AND OPERATION
1.1 Application
1.1.1 EMIS-BAR pressure transmitters (hereinafter "transmitters") are designed for continu-
ous measurement of pressure (gauge, vacuum, absolute, hydrostatic and differential (pressure differ-
ence)) and conversion of the measured pressure into a rated DC output signal 4-20 mA overlapped
with digital HART signal, as well as displaying the measured value on the display.
EMIS-BAR pressure transmitters can be used in automatic control, adjustment and operation
systems at various industries.
1.1.2 Transmitters can be operated and adjusted using an inbuilt keyboard or remotely using
HART-compatible device.
1.1.3 Transmitters with HART can transfer information about measuring value in digital form
via the 2-wire connection line along with 4-20 mA current signal. Digital signal can be received and
converted by any HART-compatible device. Digital output is used to connect transmitter with portable
HART communicator or PC via standard serial interface and additional HART modem. The following
operation can be executed: setup transmitter, select main parameters, read measured pressure, etc.
HART-protocol allows two master devices be connected to the system: HART-compatible PC and
portable HART communicator. Transmitter can receive and execute commands of each of the control
devices with different addresses and exchanging data in the time sharing mode.
Measured value is displayed in selected units on the transmitter indicator or HART communi-
cator in measuring mode.
1.1.4 Transmitter meets the requirements of the technical regulations: TR CU 020/2011, TR
CU 032/2013.
1.1.5 Transmitter can be used for both safe and explosive environments.
Ex-proof transmitters comply with the technical regulations TR CU 012/2011.

lations according to GOST IEC 60079-14 as given in the chapter 7.3 of the Russian Electrical Code
and other normative documents designed for explosive environments.
Transmitters of Exd and RV configurations have flameproof enclosure "d" under GOST IEC
60079-1-2011, ex-proof design and intended for use in explosive environments hazardous with gas
mixtures and vapours of I, IIB, IIC, IIIB иIIIC categories.
Transmitters of ЕхiaC, ExiaB and RO configurations have explosion protection "intrinsically
safe circuit "i" under GOST 31610.11-2014, with increased explosion protection and intended for use

1.4 Configuration and operation
1.4.1 Transmitter structure is shown in the fig.2.
a) Transmitter with in-line mount connection
b) Transmitter with traditional mount connection
Fig.2 - Pressure transmitter structure
EMIS-BAR
OPERATION MANUAL
15
Pressure transmitter consists of pressure sensor and electronic unit (fig.2). Electronic unit is at-
tached to the threaded socket of the pressure sensor. Transmitter includes: electronic board (4), sealed
covers (2), LCD unit (5), RFI filters (3), terminal board (8), adjusting buttons (9).
The difference between the in-line mount and the traditional mount versions is in the design of
the pressure sensor (6). For in-line mount version, the pressure transmitter consists of a housing and a
socket, where the sensor and measuring diaphragm are located. For traditional mount version, the pres-
sure transmitter consists of the sensor with measuring diaphragms located at the positive side (high
pressure side) and the negative side (low pressure), flanges (7) and fasteners.
1.4.2 The transmitter work is based on a piezoresistive method of pressure measurement, which
is based on measuring the voltage difference across the resistances of the bridge circuit of an integrated
sensitive element made of single-crystal silicon under mechanical action. Sensor is fixed on the silicon
lining, which itself fixed on the measuring diaphragm. When the pressure of the working medium
changes, the geometry of the resistances of the Wheatstone bridge and the potential difference at its
outputs change. After double conversion of an analog-digital and digital-analog signal in the electronic
unit, amplification, filtering, modulation, the current signal at the output is proportional to the change in
the pressure of medium.
1.4.3 The structure allows to rotate transmitter for 270° around the common vertical axis, while
the rotation angle is limited to the design of the rotation assembly (fig.3).
After rotation is done, tighten the lock screw to avoid accidental rotation.
270º
Fig.3 - Transmitter rotation angle
1.4.4 LCD can be rotated for 360° with fixation at each 90° for convenient reading. To rotate
transmitter follow the steps below: unscrew two screws, pull up the display, rotate and put it back down,
screw two screws.
1.5 Pressure transmitter adjustment
1.5.1 To adjust the transmitter use the input buttons (fig. 4) located at the transmitter body.
The control unit is installed in the upper part of the housing and allows you to adjust the trans-
mitter in the hazardous area without violating the seal of the transmitter casing.
To access the buttons unscrew two screws in the upper side of the casing and fold back the plas-
tic cover. Use M button to navigate and «↑» and«↓» to change. To save changes in the nonvolatile de-
vice memory simultaneously press «↑» and «↓» buttons. After that Save will appear in the lower line of
the display.

The digital parameters of the device are always changed by successively increasing the value,
starting from the lowest digit of the displayed parameter Hold «↑» or «↓» to transfer to next digit. This is
used for rough adjustment within the wide range. For accurate adjustment release button «↑» or «↓»,then
press it again.
Any write commands via HART are disabled while the transmitter is being configured using
the buttons. Reading of measured parameters is allowed.
If more than two minutes have passed since the last press of the enter button, the entered set-
tings are automatically saved and the device enters the display mode.
1.5.2 LCD displays the following:
1 - measured pressure;
2 - selected units, parameter name in configuration mode, errors;
3 - quadratic dependence of the output signal;
4 - menu line and buttons lock mode;
5 - error symbol for "Under lower limit";
6 - measured pressure symbol;
7 - error symbol for "Over upper limit";
8 - communication indicator (blinking means that data are being transferred via HART).
