SIPAN 32 and SIPAN 32X analyzers

SIPAN 32 and SIPAN 32X are analyzers of the new twoĆwire

generation with stateĆofĆtheĆart microĆpower technology with

microprocessor control and multiĆsegment display.

The SIPAN 32 and SIPAN 32X analyzers are optionally

available with special features for process use.

The SIPAN 32 and SIPAN 32X analyzers are available in field

housings.

They contain the analog and digital data processing functions

for the signal delivered by the sensor.

There are three SIPAN 32 and SIPAN 32X analyzers, each

available for the 2EL, 4EL and IND procedures.

Special characteristics of SIPAN 32

 TwoĆwire analyzer with stateĆofĆtheĆart microĆpower

technology

 Extremely simple field installation with only two wires

 Complete basic configuration

 MenuĆbased operation with understandable symbols

(based on IEC)

 Complete local operation with directly accessible keypad

with 8 keys and large, clearlyĆarranged multiĆsegment

display

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

, oleum, HNO

, HCl, HBr, NaOH, NaCl, KOH

 Direct output of concentration values instead of conductivity

(19 stored material tables)

 All measuring procedures 2EL, 4EL and IND are available

 Additional permanent temperature display selectable in

°Cor°F

Logbook with entry of faults or calibration procedures with

date and time

 Output signal 4 to 20 mA

 Fault or limit output > 20 mA

 NonĆlinear ultraĆpure water temperature compensation for

conductivity

 Automatic HOLD function

 Comprehensive fault diagnosis system

 3 operating levels with coded protection for monitoring,

routine and specialists

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

 Output of defined current values for test purposes

 Maximum electromagnetic compatibility according to CE and

NAMUR, sensitive lightning protection

 Robust field housing (IP 65/NEMA 4X) with four Pg screwed

glands for easy connection

 No special or expensive mounting set required for wall or

panel mounting

Special characteristics of SIPAN 32X

 Analyzers with type of protection "Increased intrinsic safety"

EEx ia can be used within the potentially explosive

atmospheres (zone 1, CENELEC).

Options

 Second passive output, freelyĆparameterizable as second

current output for temperature, flushing function with timer

control, limit or warning (preĆalarm)

 HART communication via handheld communicator or PC

 Only available via HART interface: 4 methods with remote

selection for complete parameter sets, not only for

measuring ranges, e.g. also limits, physical dimensions,

temperature compensation, hysteresis, calibration factors
