SIPAN 34 analyzer

SIPAN 34 is an analyzer of the fourĆwire generation with

stateĆofĆtheĆart technology with microprocessor control and

illuminated graphic display.

The SIPAN 34 analyzer is optionally available with special

features for process use.

The SIPAN 34 analyzer is available in two designs:

- With a field housing

- With a panel housing

It contains the analog and digital data processing functions for

the signal delivered by the sensor.

A SIPAN 34 analyzer can be used for all measuring ranges.

Special characteristics of SIPAN 34

 FourĆwire analyzer with extremely easy operation

 Universal power supply (24 V AC/DC, 115 V AC, 230 V AC)

 Complete basic configuration

 SelfĆexplanatory menu operation in plain text in five

languages (German , English, French, Spanish, Italian), help

function

 Operation according to NAMUR, i.e. complete local

operation with directly accessible keypad with 8 keys and

large, illuminated, fullĆgraphic display

 Display of S/cm, mS/cm, mS/cm, mS/m, MWcm, kWcm,

%w/w,H

, oleum, HNO

, HCl, HBr, NaOH, NaCl, KOH

 Direct output of concentration values instead of conductivity

(19 stored material tables)

 Additional permanent bargraph of measuring range

 Graphic trend display of measured value

 Additional permanent temperature display in °C

 Output signal 0/4 to 20 mA, floating

 FreelyĆprogrammable, permanent measuringĆpoint

designation (saves tag labels)

 Logbook with entry of faults or calibration procedures with

date and time

 Fault and limit contacts

 NonĆlinear ultraĆpure water temperature compensation for

conductivity

 All conductivity measuring procedures (2EL/4EL/IND) can be

selected, i.e. only one analyzer is required for the complete

conductivity range

 Program for automatic recording of userĆspecific temperature

compensation

 Maintenance switch with automatic HOLD function

 Comprehensive fault diagnosis and preventive maintenance

system in plain text

 3 operating levels with coded protection for monitoring,

routine and specialists

 Selectable tests for: keys, RAM, EPROM, EEPROM, display

 Output of freelyĆdefined current values for test purposes

 Maximum electromagnetic compatibility according to CE and

NAMUR, sensitive lightning protection

 Panel housing made completely of metal, CE safety for every

control cabinet installation engineer

 Robust field housing (IP 65) with seven Pg screwed glands

for easy connection

 No special or expensive mounting set required for wall or

panel mounting

Options for SIPAN 34

 Second current output for measured value or temperature

with additional limit

 Four parameter sets with remote selection for complete

methods, not only for measuring ranges, e.g. also limits,

physical dimensions, temperature compensation with

complete characteristic (not only TC value), hysteresis

 Individual calibration of each parameter set possible

 Automatic cleaning function (3 relays) for cleaning, flushing,

fitting control with cyclic time input, waiting and holding

functions

 TwoĆpoint controller for pulse length (dosing valves) or pulse

frequency (diaphragm pumps)

 Additional switching contact for maintenance (function

check) and preĆalarm (warning)
