IP Transducer
two version in the I/P’s the 77-16 & the 773 I/P. EIL
and most of the other major consultants has approved both
these I/P’s. They are also appreciated by a number of End
Users for their satisfactory operation.
The 773 I/P is a newer version launched in 1996. This I/P
Converter employs a True Electronic Feedback. It has a number
of approvals Like CENELEC, CCOE, CMRI, IP 66 protection Class
approval. This I/P’s have been working in critical applications
in Fertilizer, Petroleum, and Chemical industry.

CONTROLS
 -Single
Loop Controller With Relays
The controller series comprises
universal and freely programmable compact instruments for
a variety of control tasks. It consists of five models, with
the bezel sizes 96mm x 96mm, 96mmx 48mm in portrait and landscape
format, 48mm x 48mm and 48mm x 24mm.
The controllers feature a clearly readable 7-segment display
which, depending on the version, is 10 or 20 mm high, for
process value and set point indication or for dialogs. Only
three keys are needed for configuration. Parameter setting
is arranged dynamically, and after two operation-free seconds
the value is accepted automatically. Self-optimization, which
is provided as standard, establishes the optimum controller
parameters by a key stroke. The basic version also includes
a ramp function with adjustable gradients. A timer function
has been integrated as an extra.
All controllers can be employed as single-set point controllers
with a limit comparator, or as double-set point controllers.
The linearizations of the usual transducers are stored. Protection
is IP65 at the front and IP20 at the back. The electrical
connection is by a plug-in connector with screw terminals.

-Universal Single Loop Controller
With Analog Output
This is a compact mini processor
based controller with auto-tuning and fuzzy logic. With universal
I/P''s freely assignable O/P it is ideal for furnace control,
and single loop applications. The option of Modbus gives you
a Human Machine Interface (HMI) as well.
----------------------------------------------------------------------------------------------------------------------------------------------
-Universal Single
Loop Controller With Profile Control
 This
series of universal, freely configurable process controllers
is available in the formats 96mm x 96mm and 96mm x 48mm (portrait
and landscape format).
The instruments feature two 4-digit 7-segment displays, five
or eight LEDs for indication of the switching status and operating
modes, an 8-digit matrix display, as well as six keys for
operation and configuration.
The user has flexibility in assigning the slots of the controller
according to the block structure.
Additional functions include self-optimization, parameter
set switching, and up to eight limit comparators.
Linearizations for conventional transducers are held in the
memory; a customized linearisation table can be programmed.
The process controller can be adapted to a variety of tasks
with the aid of a maths module.
The instruments can be integrated into a data network via
a serial interface, or can be expanded through an external
relay module.
A setup program is available for easy configuration from a
PC.
The electrical connection is at the rear by screw terminals.
 ----------------------------------------------------------------------------------------------------------------------------------------------
-Universal
Multi Loop Process Controller
This is a process and program
controller with up to 4 controller or program channels. The
instrument is built to the format 144mm x 130mm for a standard
92mmx 92mm panel cut-out and a mounting depth of 170mm.
The display is a 5" color graphics display (27 colors).
The layout of the screen templates can be individually adapted
and adjusted. Two freely configurable screen templates make
it possible to customize the placing of texts, process values,
background pictures and icons.
A maximum of 4 analog inputs and 6 logic inputs are available,
as well as six expansion slots for switched or analog outputs.
A setup program is available for comfortable configuration
from a PC.
Linearizations for the usual transducers are stored within
the instrument, four customer specific linearization tables
can be programmed.
A math and logic module can be used to adapt the instrument
to a very wide range of control tasks.
Two serial interfaces, RS422/485 or Profibus-DP, can be used
to integrate the instrument into a data network. Modules can
be retrofitted quite simply by the user.
The electrical connection is made at the rear of the instrument,
via plug-in screw terminals.

-Process Automation Controller
The Process Automation Controller
is a stand-alone, microprocessor-based industrial controller
designed for a broad range of process applications. It can
serve as a simple single-loop controller or as a multi-loop
controller with complete control and logic functions for a
small unit batch or continuous process. The Model 353’s fieldbus
and networking options enable it to function as an integral
element in a plant system.
Loops are configured for control, sequence, or logic as needed
within the Model 353. Each configured loop can have a virtual
operator display that is viewed locally using the LOOP button
on the faceplate and is mapped to network communication for
a plant operator station. Alarm management is handled using
the L (Loop) & S (Station) indicator lights along with
the priority assignments and flashing options of each alarm.

PRESSURE
AND TEMPERATURE
TRANSMITTER
-Non SMART Pressure Transmitter
Pressure transmitters are used to measure the relative (gauge)
and absolute pressures in liquids or gases. The measuring
device for the transmitter is a piezo-resistive element or
a thin-film strain gauge. The pressure is converted into an
electrical signal.
----------------------------------------------------------------------------------------------------------------------------------------------
-SMART Pressure Transmitters
A true smart transmitter, it is fitted with most advanced
remote diagnostic tools available. It even reads process and
ambient temperatures, and gives in-parallel performance in
terms of stability, range ability and accuracy.
Various versions of the SITRANS P transmitter, DS III series,
are available with a two-wire circuit. The output signal is
a load-independent direct current of 4 to 20 mA linearly proportional
to the input pressure.
Transmitters conforming to the type of protection "Intrinsic
safety" and "Explosion-proof" may be installed
within potentially explosive atmospheres (zone 1) or zone
0. The transmitters are provided with an EU prototype test
certificate and comply with the corresponding harmonized European
standards of the CENELEC.
Transmitters with the type of protection "Intrinsic safety"
for use in zone 0 may be operated with power supply units
of category "ia" and "ib".
----------------------------------------------------------------------------------------------------------------------------------------------
 -Temperature
Tranmsitter with HART
The 2-wire transmitter uses resistance thermometers or
thermocouples to acquire the temperature. With resistance
thermometers, the probe can be connected in 2/3 or 4 wire
circuit.
----------------------------------------------------------------------------------------------------------------------------------------------
PAPERLESS RECORDERS
 -Logoscreen
CF Paperless Recorder
Together with its PC software components, this recorder constitutes
a system for the electronic acquisition, storage, archiving
and analysis of a substantial amount of data.
The recorder is internally equiped with 6 or 12 universal
measurement inputs and can be expanded to a maximum of 36
inputs through the mTRON automation system. The aquired process
data are saved to the internal backup memory (32 to 128 MBytes)
and transfered via the Compact Flash Memory Card, which is
plugged in at the front. An optional Ethernet interface provides
integration into PC networks in order to allow data to be
accessed via networked PC stations. The recorder can be configured
from 8 keys or from a PC. Front bezel size is 144mm x 200mm,
max. depth behind panel is 228mm.
