General features

Modular design

Quick setup To the first measuring value within 1 minuteAfter setting up the few parameters in the Quick Setup menu, the measuring point is ready to measure. You can be sure, to have set up the most important settings.The first measuring value is reliably displayed.

Navigator and plain text The unique operating concept sets new standards: Fewer user errors thanks to very easy operation Quick configuration with the Navigator. Intuitive configuration and diagnosis due to plain text display

Sensor monitor Pressing the DIAG key takes you to the sensor monitor. All the important sensor data, incl. warning and alarm limits, are graphically displayed in one go.

Process check system (PCS) This function checks the measuring signal for stagnation. If the measuring signal does not change for some time (several measured values), an alarm is triggered. Soiling, blockage or similar could be the cause of such behaviour.

Software packages The standard software contains the following features:

Safety Safety integration level acc. to IEC 61508 (SIL 2)

Liquiline is the first analysis transmitter to be developed to IEC 61508 and specified for use under SIL 2.The development to SIL 2 reduces the probability of hidden errors and stands for the highest degree of reliability.

Alarm LED

A bright, red LED draws your attention to an error (22 mA alarm).

Code protection

Liquiline is supplied without access protection.

You can specify passwords linked to relevant access rights for various user groups: Specialist Service Operator...

To guarantee the highest degree of safety and security in the pharmaceuticals sector, you can specify user roles with IDs and passwords as per 21CFR11.

Reordering validated software

You can order new devices with older, validated software so you do not have to constantly validate new software versions of new devices. This is possible as long as allowed by the hardware version.

Special features

pH / ORP Sensor Condition Check (SCC)

This function monitors the state of the electrodes or the degree of electrode ageing. The "Electrode OK", "Low wear" or "Replace electrode" messages inform you on the state of the electrode. The electrode state is updated after each calibration. When the "Replace electrode" message appears, an error message is displayed.

Sensor Check System (SCS)

The sensor check system alerts to deviations of the pH glass impedance or reference impedance from the normal range, thus indicating possible failure due to pH electrode blocking or damage.

Conductivity Polarisation monitoring

Polarisation effects in the boundary layer between the sensor and the solution to be measured limit the measuring range of conductive conductivity sensors.The transmitter can detect and indicate polarisation effects using an innovative, intelligent signal evaluation process.

United States Pharmacopeia (USP) and European Pharmacopoeia (EP)

The requirements on ultrapure water in the pharmaceutical industry are specified by the American USP and the European EP.

The transmitter meets the USP/EP requirements on conductivity measuring systems: Precise temperature measurement at point of conductivity measurement Simultaneous display of uncompensated conductivity values and temperature Display resolution 0.01 S/cm Exact adjustment of the transmitter in the factory with traceable precision resistances (optional) Exact adjustment of the sensors in the factory in accordance with ASTM D 1125-9 resp. ASTM D 5391-99

(optional) Temperature-dependent measured value monitoring acc. to USP and EP.

Digital sensors Memosens

The measuring point is safer with Memosens: No-contact, inductive signal transmission, thus optimum galvanic separation No contact corrosion Completely water-tight Automatic error message if data flow interrupted Sensor calibration possible in laboratory Look-ahead maintenance thanks to recording of sensor data, e.g.:

Total hours of operation Hours of operation for very high or very low pH values Hours of operation for high temperatures above 80 C (176 F) and 100 C (212 F) Number of steam sterilisations
