Concentration tables

When the device is delivered from the factory, tables are saved in the device that allow inductive

conductivity measurements to be converted to concentrations of certain substances. 4 user-defined

tables are also possible.

The following factory concentration tables are available:

NaOH

0 to 15 %

0 to 100 ˚C (32 to 212 ˚F)

NaOH

25 to 50%

2 to 80 ˚C (36 to 176 ˚F)

HCl

0 to 20 %

0 to 65 ˚C (32 to 149 ˚F)

HNO3

0 to 30 %

2 to 80 ˚C (36 to 176 ˚F)

H2SO4

0.5 to 27 % and 35 to 85 %

0 to 100 ˚C (32 to 212 ˚F)

H2SO4

93 to 100 %

10 to 115 ˚C (50 to 239 ˚F)

H3PO4

0 to 40 %

2 to 80 ˚C (36 to 176 ˚F)

NaCl

0 to 26 %

2 to 80 ˚C (36 to 176 ˚F)

Security

Real-time clock

The device has a real-time clock, which is buffered by a button cell battery if the power supply fails.

This ensures that the device continues to keep the correct date and time when it is restarted and that

the time stamp for the logbooks is correct.

Data security

All settings, logbooks etc. are stored in a non-volatile memory to ensure that the data are retained

even in the event of a disruption to the power supply.

Measuring range switching for conductivity

• Can be used in CIP processes e.g. for safe monitoring of phase separations

• Switching between 4 complete parameter sets:

• Conductivity operating mode

• Concentration tables

• Temperature compensation

• Output signal range

• Limit value switch

• Via digital inputs or fieldbus

Measured value compensation for oxygen and conductivity

• Pressure or temperature compensation

• Input signals from external sensors via current input or fieldbus

• Signals from connected temperature sensors

Password protection

Password-protected login

• For remote operation via web server

• For local operation

Process safety

Two independent PID controllers

• One- or two-sided control

• Limit switches

• 4 cleaning programs which can be programmed independently of each other

IT security

Our warranty is valid only if the device is installed and used as described in the Operating

Instructions. The device is equipped with security mechanisms to protect it against any inadvertent

changes to the settings.

IT security measures, which provide additional protection for the device and associated data transfer,

must be implemented by the operators themselves in line with their security standards.
